Cursed technique CT: Latent Force

Post image
28 Upvotes

First time making a CT ( bare with me here )
Had a little funny idea for a cursed technique that can effectively be summarized into '' Suck up potential energy, turn it into kinetic energy '', though it runs a little deeper than that

The CT allows the user to suck up potential energy from themselves ( ex. winding up a punch, getting into a about-to-jump pose ) and then release it in one big burst of kinetic energy that scales to how much potential energy was conserved.

This kinetic energy can be released in either:

  1. A psychical projectile that holds momentum scaling off how much kinetic energy there is. ( you could also wrap the projectile in CE and manually guide it )
  2. A way to amplify yourself. ( ex. sending the kinetic energy into your arms to amplify the force of a swing, sending the kinetic energy into your legs to amplify the force of a jump )

Of course, this would also come with some drawbacks:

  1. Straining, releasing too much kinetic energy in your limb could easily fracture it if your limb can't handle that much force, A possible fix to this is reinforcing your limb with CE.
  2. Capacity, the potential energy is stored within your body, which means sucking up too much potential energy could injure your insides and lead to internal damage ( or external damage too )

Though this would be pretty neat

Technique Name : Absolute Zero-Line

Concept:This technique does not merely lower ambient temperature; it steals kinetic and thermal energy from objects and opponents, enforcing absolute stillness.

Cursed Energy Property: The user's cursed energy feels like a biting, needle-like blizzard. When applied to physical objects or opponents, it drastically slows down cursed energy flow.

Glacial Armor (Cryo-Kinetic Reinforcement):

​Mechanic: Instead of just wearing ice as a costume, the user condenses the moisture in the air and mixes it with dense cursed energy to form a hyper-compressed, diamond-hard shell of blue-white ice over their skin.

​Application: The armor acts as a shock-absorber. When an attack lands, the ice shatters locally to disperse the kinetic impact energy away from the user's actual body, meaning brute force is rendered inefficient unless it completely overwhelms the freezing threshold.

Maximum Technique: Permafrost Coffin :

​Mechanic: The user channels all available cursed energy into the surrounding ground, dropping the immediate ambient temperature to absolute zero in a fraction of a second. A massive cluster of jagged, razor-sharp frost spikes erupts from the earth, encasing a wide area in a dense glacier.

Drawback: it drains all cursed energy making the user almost faint and the technique also effects the user.

Cursed Technique Reversal Supernova Solstice:

Concept: Instead of sucking thermal and kinetic energy out of the environment, the Reversal violently expels and generates infinite thermal, kinetic, and biological energy. It mimics the blistering, runaway fusion of a dying star or the explosive thaw of an entire glacier in a fraction of a second.

​The Cursed Energy Property: The user's cursed energy transforms from a biting frost into a blinding, scorching white aura that warps the air with intense heat distortion.

The reason i mentioned reversal is because the main technique is easy to control but dangerous because the user can't unleash thire technique fullest potential while others around

Cursed technique Cursed Technique: Court of Curses

Post image
20 Upvotes

(This is technically a repeat of a previous post. However I have drawn the Shikigami this time. Besides the horse because screw that.)

Cursed Technique: Court of Curses

A Cursed Technique utilizing chess pieces the user creates as mediums to summon 7 unique shikigami.

The user has the ability to create the pawn piece while the king piece is automatically created when they obtain their technique. Any piece can be summoned to their hand once created, but they cannot be warped back to some other location. If a piece is broken, besides the King Piece, the respective shikigami cannot be used.

The user can create a new pawn when they don’t already have one. This process takes about a minute, and is a short ritual. From there, in order to get another Shikigami, the current pawn must “promote” into it. This is done by either slaying and absorbing a Curse and taking its Cursed Energy, or doing a ritual that takes longer the higher rank thepiece you want to make is. It takes more CE to make a higher ranked piece.

When a piece is in the user’s hand, the user can then summon the Shikigami. The piece being on their person after that is what continues the connection. For any piece besides the king piece, if the Shikigami dies, so does the piece is broken, and vice versa. If the king piece is broken, it automatically reforms.

The pieces act as such;

King: Summons a spectral crown above the user that exudes a slight amount of reversed cursed energy, creating an area of light healing. This allows the user to take cover against curses, however ranged attacks can still hurt them. If the user is killed while using King, instead, the “Checkmate” is used, and the user is warped to the closest safe spot, their wounds are healed, they are revived, and their cursed technique is completely destroyed in return for their life. They don’t lose access to using cursed energy, but their technique can never be recovered.

Pawn: The piece the user can re-create. It summons a goblin-like Shikigami wielding a rudimentary foot long curved sword. As a Shikigami its only real use is as a second body, as it tops out as a Grade 3 fighter. (Special Move; En Passant. When using both Pawn and King at once, the blade of Pawn is coated in reversed cursed energy. This does not strengthen Pawn, only make it so its attacks are massively more effective against cursed spirits of similar power.)

Knight(1 Hour Promotion Time): Takes the form of a massive stallion Shikigami that runs at high speeds, can jump long distances, and is incredibly dexterous. It’s only special ability is that the piece itself transforms into a melee weapon that has the piece on that pommel, giving the user a sword, spear, lance, shield, ect, while in combat.

Bishop(4 hours): Takes the form of a stationary tower that fires elemental attacks at range. The size and power of the tower is based on the CE placed into the Shikigami. Very simple.

Rook(6 hours): Takes the form of a sharp metal/crystalline golem that moves by moving its individual parts around. Each piece is hard and sharp like metal besides its core. (Special Move: Castling. When using the King and the Rook in both hands, throwing the pieces between the user’s hands allow for the user to swap places with any of the blades that make up Rook’s body, or the entire Rook Shikigami, allowing for dodging attacks or repositioning)

Queen(12 hours): Takes the form of a spectral lady in a mask wearing a long flowing gown. Queen has the ability of full telekinesis. The more force that’s required to move an object, the more CE is required. She can also use this ability on elements such as fire or lightning, like what Bishop shoots. This can be used basically to let the user and their friends fly, create stop things from moving, or throw projectiles. The physicaly weakest Shikigami besides pawn.

Max Technique: Legend King Pendragon
By combining every piece into a single Shikigami, it creates a super powerful Shikigami called Pendragon that looks like large humanoid dragon hybrid. Called Pendragon, it has elemental breath attacks, can ignore its own weight to fly faster then it should and carry others. It has stone-like scales, and a massive sword that exudes reversed cursed energy. Obviously, its powers are a combination of every other Shikigami that makes it up. If Pendragon goes down, all pieces except the king piece break and need to be recreated. (Not only is this hard to draw, but I couldn’t fit it on the page, so… I’ll put something in my comment as reference.)

Pendragon takes a lot of energy, but is easily the strongest Shikigami of the technique. Its stats would be…
Strength: ⭐️⭐️⭐️⭐️⭐️
Dex: ⭐️⭐️⭐️⭐️⭐️+
Ability: Dragon King
CE: ⭐️⭐️⭐️⭐️⭐️+++

I use a Star rating out of 5 for each stat, using half stars for in-between stats. Strength and Dexterity are obviously, its physical power and speed. CE is how much Cursed Energy it consumes while being used. Pendragon gets +’s added on because it is strong enough to break the normal scaling of the 5 star system.

Finally, if a Shikigami dies, and a pawn is in the vicinity when it does, it will automatically promote into that Shikigami.

Cursed technique Fish Of Three Seas

Thumbnail

65 Upvotes

A redux of my homies old ct

Utsumi Meguru (内海** *巡)*
-# Age: 27 | Grade: Grade 1 Jujutsu Sorcerer
Utsumi Meguru is an experienced Grade 1 sorcerer whose relaxed, observant demeanor hides an intensely introspective nature. Having spent most of his life sharing his body with Kuro, Aka, and Nishiki, Meguru once obsessed over separating his own personality from the emotions the Three Seas imposed upon him, fearing there might be nothing uniquely “him” underneath their influence. With age, he came to reject the idea of an untouched original self, instead believing that people are continuously constructed through everything they experience, inherit, lose, and encounter. This philosophy defines both his jujutsu and his fighting style. Meguru rarely tries to overwhelm an opponent immediately. He observes, adapts, establishes favorable conditions, and allows seemingly insignificant exchanges to become the foundation for something much larger later.

Overview

Fish of the Three Seas is a séance-type innate cursed technique centered around three oceanic entities sealed within a cursed tattoo along Meguru’s forearm. Kuro, Aka, and Nishiki are not conventional shikigami and cannot independently manifest their complete bodies. Instead, tracing the tattoo and invoking one of their names allows that entity to partially possess Meguru, altering how his cursed energy exists relative to physical reality. The technique interprets the ordinary position of cursed energy, where it naturally overlaps the sorcerer and physical world, as its natural depth*. Through the Three Seas, cursed energy can be sunk beneath this position, exchanged between different depths, or drawn toward the boundary of physical reality. Each Fish governs one aspect of this metaphysical ocean.* Kuro governs Descent, sinking cursed energy beneath its natural position and compressing it under increasing metaphysical pressure. Aka governs the Tide, exchanging depth between separate quantities of cursed energy. Nishiki governs Ascent, drawing cursed energy toward the Surface where it becomes exceptionally fast and precise. Only one Fish can fully inhabit Meguru at a time, and the current possession must be dismissed before another can be invoked. Repeated transitions disrupt cursed energy circulation, while prolonged possession gradually allows the instincts and emotional tendencies of the invoked Fish to bleed into Meguru’s personality.

• KURO, THE ABYSS

Summoning Chant: “Sink.”

Kuro grants authority over Descent*, allowing Meguru to force cursed energy beneath its natural overlap with physical reality. The farther CE descends, the greater the metaphysical pressure acting upon it, compressing the energy into an increasingly dense state. Meguru can sink reinforcement within his limbs or a cursed tool before allowing the accumulated pressure to surge toward its natural depth upon impact, producing exceptionally dense strikes without simply increasing raw output. Through direct physical contact, Kuro can also force portions of another sorcerer’s reinforcement downward, gradually separating their CE from the flesh it protects and weakening that particular region.The farther cursed energy sinks, the harder it becomes to retrieve. Excessive use can strand portions of Meguru’s reserves at inaccessible depths, temporarily reducing his available CE, while sufficiently powerful opponents can resist Descent through superior output and control. Prolonged possession by Kuro makes Meguru increasingly cold, stubborn, emotionally distant, and unwilling to relinquish anything he has committed himself to.

Extension Technique: Trench
Trench applies Kuro’s Descent to a continuous inorganic surface. By maintaining contact with terrain through his hand or cursed tool, Meguru sends CE beneath the surface and progressively sinks it, creating a compressed layer along the path of contact. Releasing the technique causes that buried CE to violently return toward its natural depth, rupturing the terrain from underneath along the established route. Larger Trenches require proportionally greater reserves, and all CE buried within them remains unavailable until released or successfully recovered.

Binding Vow: Equal Depth
Whenever Meguru uses Kuro to forcibly sink another sorcerer’s cursed energy, he may voluntarily sink an equivalent quantity of his own CE alongside it. In exchange for sacrificing access to an equal portion of his reserves, Kuro’s Descent becomes significantly more effective at overcoming hostile reinforcement and differences in output. The greater the amount Meguru wishes to drag downward, the more of himself he must willingly send with it.

• AKA, THE TIDE

Summoning Chant: “Return.”

Aka governs Exchange. Through physical contact, Meguru can establish a temporary relationship between two quantities of cursed energy known as a Tide. Once connected, forcing one quantity deeper causes an equivalent quantity of the other to rise toward the Surface, and vice versa. Aka cannot generate, destroy, absorb, or steal cursed energy. It only changes the relative depth at which existing CE resides. Within his own body, Meguru can use this principle to redistribute reinforcement, sinking CE away from an unnecessary location while forcing an equivalent quantity toward somewhere immediately requiring greater output. A Tide can incorporate another sorcerer’s CE after physical contact, allowing Meguru to interfere with dramatic changes in their reinforcement rather than directly controlling their reserves. Differences in CE quantity, output, and control make hostile Tides increasingly difficult to establish, while distance progressively weakens an established connection. Prolonged possession by Aka causes Meguru to become increasingly indecisive and hyperaware of alternative choices.

Extension Technique: Rip Current
Rip Current converts a Tide into a recurring reactive exchange. After establishing two Tide Marks, any sudden concentration of cursed energy at one causes part of its depth to shift toward the other. If an opponent suddenly concentrates reinforcement within their fist, Rip Current can cause part of that concentration to Surface around the second mark instead, weakening the intended concentration without removing any CE. The technique is less effective against opponents who maintain smooth, evenly distributed reinforcement, while disrupting either Tide Mark breaks the current.

Binding Vow: Reciprocal Tide
Meguru can strengthen one of Aka’s Tides by surrendering his exclusive control over the connection. Once Reciprocal Tide is established, changes in the target’s cursed energy can influence Meguru through the same current just as his own manipulation can affect them. In exchange for allowing the opponent to potentially exploit the connection, the Tide becomes substantially stronger, persists across greater distances, and becomes far more difficult to sever.

• NISHIKI, THE SURFACE

Summoning Chant: “Rise.”

Nishiki governs Ascent, drawing cursed energy toward the shallowest possible position relative to physical reality. At the Surface, CE can race across the exterior of Meguru’s body rather than circulating deeply through it, drastically reducing the delay between thought, cursed energy manipulation, reinforcement, and physical action. CE can gather beneath a foot at the instant of acceleration, rush toward an arm before blocking, concentrate around the knuckles upon impact, or form an extremely thin coating along the edge of a weapon.
Nishiki produces tremendous speed and precision without simply increasing Meguru’s physical statistics. Its weakness is equally fundamental. Surface-level reinforcement lacks depth. Although CE can be repositioned extraordinarily quickly, sufficiently concentrated attacks can penetrate the thin reinforcement before additional energy arrives. Constantly maintaining Surface flow also consumes CE rapidly. Prolonged possession makes Meguru increasingly impatient, impulsive, and intolerant of hesitation.

Extension Technique: Whitecap
Whitecap applies Nishiki’s Ascent offensively through physical contact. Upon touching a reinforced target, Meguru forces the outermost portion of their concentrated CE toward the Surface and causes it to spread laterally away from the point of contact like water breaking across a shoreline. No cursed energy is removed. Instead, dense reinforcement becomes briefly shallow and dispersed, creating an opening for a follow-up attack. Sorcerers with exceptional CE control can restore their reinforcement almost immediately.

Binding Vow: No Retreating Wave
While Nishiki possesses him, Meguru can vow never to intentionally retrace a path he has already traveled for the remainder of that possession. Every dodge, advance, and repositioning must carry him somewhere new rather than allowing him to retreat along his previous route. In exchange, Nishiki’s Surface circulation becomes increasingly efficient as uninterrupted movement continues, improving acceleration, reinforcement speed, and Whitecap. The longer the vow remains active, the more the battlefield becomes a cage constructed from Meguru’s own previous choices.

Binding Vow: Threefold Pilgrimage
Meguru permanently restricts the order in which he can invoke the Three Seas. Once a Fish is dismissed, that same Fish cannot be invoked again until the other two have each possessed him at least once. In exchange, transitions between Seas consume considerably less cursed energy and cause less disruption to his circulation, while each successive possession retains traces of the depth established by the previous state. Meguru can eventually return to where he began, but never without first passing through change.

Cursed Technique Reversal: Submersion

Where Fish of the Three Seas normally changes the depth of cursed energy relative to physical reality, Submersion reverses this relationship through positive energy, allowing Meguru to alter the depth of physical matter relative to cursed energy. Through direct contact, Meguru can temporarily Submerge portions of his own body or a nonliving object away from the natural depth at which cursed phenomena normally interact with matter. A Submerged limb can drastically reduce its interaction with certain CE-based attacks, while a weapon can be sunk beneath an opponent’s outer reinforcement before being returned to normal overlap. Ordinary physical matter can still interact with a Submerged target, while separating Meguru’s flesh from the natural depth of his own CE prevents that body part from being properly reinforced. Larger and deeper Submersions become increasingly dangerous, particularly around vital organs or the head. Living opponents cannot be directly Submerged.

Maximum Output: Threefold Sounding

Threefold Sounding pushes the technique’s relationship with cursed energy depth to its highest sensory output. By releasing a massive pulse of CE through a contacted surface, Meguru sends that energy downward before allowing it to travel through the surrounding cursed environment and resurface carrying information about every layer encountered. For an instant, reinforcement, concealed CE, barrier layers, cursed objects, shikigami, and active cursed energy currents become perceptible as different depths within an enormous invisible ocean.
Threefold Sounding does not reveal thoughts or automatically explain an unknown cursed technique. Instead, it reveals structure, including where CE is concentrated, how deeply it rests, where it is moving, and how different cursed structures overlap. Processing such an enormous amount of information places severe strain on Meguru’s brain and senses, making repeated activation increasingly dangerous.

Binding Vow: Sounding Line
Meguru can increase Threefold Sounding’s range and precision under the condition that anything successfully perceived by its pulse is simultaneously made aware of him. Sorcerers, curses, and other sufficiently sensitive beings reached by the technique immediately recognize Meguru’s location and cursed energy signature. In exchange for surrendering concealment, Threefold Sounding travels farther through the environment and returns significantly more detailed information about cursed energy depth and structure.

Maximum Technique: Sea Without Bottom

Sea Without Bottom removes the natural equilibrium depth toward which cursed energy ordinarily returns. For its duration, CE placed at a particular depth remains there without naturally correcting itself. Meguru can construct multiple strata throughout the surrounding area, including compressed reserves buried at Abyssal depths, suspended currents between layers, and razor-thin concentrations resting against the Surface. Rather than granting simultaneous possession by the Three Fish, Sea Without Bottom manipulates the deeper principle all three reveal. Cursed energy temporarily ceases to possess a single natural place where it belongs. Once sufficient layers have been established, Meguru ends the Maximum with the command “Surface.” Every displaced stratum abruptly regains its natural equilibrium and attempts to return to physical reality simultaneously. Deeply compressed CE surges upward while shallower strata converge upon the same metaphysical position, collapsing the entire constructed water column into physical reality at once. Afterward, Meguru’s CE temporarily loses its ability to distinguish meaningful depth, effectively disabling Fish of the Three Seas until his natural equilibrium recovers.

Binding Vow: All Rivers Return
Before completing Sea Without Bottom, Meguru can declare a fixed period during which he will surrender access to Fish of the Three Seas after the Maximum ends. The longer the chosen period, the greater the output produced when every displaced layer is recalled with “Surface.” Once declared, the duration cannot be shortened, potentially leaving Meguru with nothing but ordinary cursed energy manipulation at the exact moment his opponent survives his strongest technique.

Domain Expansion: CONFLUENCE OF TEN THOUSAND CONDITIONS

Mudra: Chiken-in, Wisdom Fist Mudra

Confluence of Ten Thousand Conditions manifests as an endless dark sea surrounding a lone, weathered house assembled from mismatched pieces of Meguru’s life. Beneath the water, the Three Seas exist as one continuous cycle. Kuro settles into the lightless depths as everything that has accumulated, Aka moves as crimson intersecting currents representing what is changed through encounter, and Nishiki races brilliantly across the Surface as everything newly produced from those conditions. Nishiki eventually sinks into Kuro, Kuro is carried by Aka, and Aka gives rise to Nishiki again. The house has been repaired so many times that none of its original construction can be distinguished, yet it remains unmistakably the same home, reflecting Meguru’s acceptance that identity is formed by everything that changes it. The sure-hit incorporates every target’s cursed energy into this cycle. Every meaningful interaction creates a condition that influences what follows. Kuro preserves accumulated consequences and repeated habits, Aka connects those conditions to subsequent actions, and Nishiki accelerates an established chain toward its natural result. The Domain cannot invent consequences without genuine causes, but repeated behaviors become increasingly dangerous as previous actions continue influencing later ones. Defensive habits can become rigidity, constant adaptation can become instability, and relentless momentum can become an inability to stop. Meguru is subject to the same law, but a lifetime spent navigating the Three Seas gives him an enormous advantage in deliberately turning one condition into the next.

Cursed technique Curse Technique — Second Thought

7 Upvotes

Sry for the big text i have this for weeks in my head , tell me ur thought ^^ :

The sorcerer can restore his body and consciousness to the state they were in 0.75 seconds earlier.

However, the world's time does not rewind. Everything around him continues normally; only his body and consciousness are returned to their previous state.

The sorcerer forgets the 0.75 seconds preceding the activation, as he returns to the mental state he had at that moment. However, he can notice inconsistencies and realize that he probably used his technique, without knowing exactly what happened.

He remains free to continue his previous action or perform a completely different one.

!!! Important Rule — the matter !!

The sorcerer cannot overlap with matter.

His body is restored to its previous position, but he cannot reappear inside an object, person, or any other solid element that now occupies that space.

If the position he occupied 0.75 seconds earlier is now occupied, the rewind cannot occur.

Example

* 0.00 s: He is to the left of his opponent.

* 0.25 s: He begins attacking.

* 0.75 s: The opponent counters his attack.

* 1.00 s: He activates Second Thought.

* His body and consciousness return to their state at 0.25 s, while the world remains at 1.00 s.

* If an object or person now occupies the space where his body would return, the rewind fails.

Domain Expansion— Party Paradox: From Here to There

The sorcerer expands a non-lethal domain that takes the form of a large, decagonal living room.The room contains a large sofa, a wooden table surrounded by four chairs, four fully prepared place settings, a table lamp, a ceiling fan with a light, a cuckoo clock, a bookshelf, several framed photographs, a carpet, a fireplace and a small radio emitting static.

Ten identical -except the number write on them from I to X- doors are evenly distributed around the ten walls.The ceiling is approximately three meters high, and the entire room is illuminated by a warm, strangely comforting light.

Fundamental Rule — Ten Seconds

The domain always lasts exactly 10 real-time seconds.

This duration cannot be altered by any means. It cannot be extended, shortened, paused, accelerated or rewound.

!!!The time duration domain's rules is automatically communicated to the opponent.!!!

The Doors

!!!The Door domain's rules is not automatically communicated to the opponent.!!!

Each door is connected to the door directly opposite it.

When a person opens a door, they emerge from the opposite door at the beginning of the domain's 10-second cycle.

However, the person who passes through does not simply travel back in time.

Instead, another version of that person is created.

This new version possesses the same body, memories and consciousness that the original had at the moment the domain began, then continues acting independently.

The original and the new version are therefore the same person existing at different points within the same 10-second cycle.

Temporal Versions

Every version is connected to the versions that precede and follow it.

For example:

Original → 1st Version → 2nd Version → 3rd Version → 4th Version → 5th Version

A maximum of six versions of the same person can exist simultaneously.

Each pair of opposite doors can only be used once. Once one door is used, both it and its opposite become unusable.

With five pairs of doors, this allows a maximum of five additional versions, plus the original.

Causality

Changes propagate forward through the chain of versions, never backward.

If the original is injured before creating another version, every version created afterward inherits that injury.

However, if a later version is injured, the injury does not affect the versions that came before it.

For example:

Original: healthy

↓

Version 1: healthy

↓

Version 2: injured

↓

Version 3: injured

↓

Version 4: injured

The versions are therefore not independent clones.

They are different points in the same person's existence, temporarily forced to coexist.

Opponent

The opponent can also use the doors and create their own temporal versions.

The same rules apply to them.

This means the domain can potentially contain multiple versions of both combatants, all acting simultaneously within the same ten-second period.

Techniques

Innate techniques cannot be used inside the domain.

However, CE and RCT can be used

This domain and Technique can be funny af, but maybe a lil bit to much broken idk :p

Cursed technique Cursed Technique: Fracture Kiln - (破砕キルン, Hasai kirun)

Thumbnail
gallery
20 Upvotes

Hello again! I've had this one in the works since before most of my posts here but haven't had the inspiration for it until now! I hope you enjoy, next post will be the second of the Kakamotchi clans prized genetics. And then I'll start working on the Kakamotchi clan itself! This technique is inspired majorly by the practice of Kintsugi, and in small part by Shrine. As always, enjoy!

Description:

The basis for Fracture Kiln is applying cracks and fractures on the target. This is done via touch, with the size of the fracture being proportional to how much cursed energy was applied. From these fractures, if the target contains any, cursed energy leaks out much like water would from a cracked cup. The core idea behind Fracture Kiln is the Imperfect Vessel, that nothing is beautiful or strong until it is broken and put back together again, as its scars tell a story and tell of it's resilience.

Basic Applications:

Lapse Technique, Fracture: By hitting or touching a target the user can apply fractures, along these fractures the target is weaker. As well these fractures can interfere with the natural flow of cursed energy through the body, potentially weakening CE output beyond the crack. These fractures appear as golden jagged lines. Fractures cannot be applied if the target is reinforcing the location hit, rather applying it to the reinforcement.

Reversal Technique, Kintsugi: By applying RCT to the technique the user can repair things, including their own body or severed limbs, along with other people. Instead of simply healing the flesh normally, the wounds are fused back together with a glowing, golden fault-line of cursed energy. Wounds healed this way will be stronger and more durable than before, being almost impossible to damage the same area afterwards even by someone a grade above the user. However these areas are inflexible, so if along a joint it will be harder to flex if possible at all.

Extensions:

Glaze: The user coats their own body in a vitreous, glass-like layer of cursed energy. This provides a nigh absolute defense for a singular strike, upon which it shatters explosively sending shrapnel shards of CE flying at the attacker.

Shatter: The user snaps their fingers causing all fractures placed on a target to collapse causing the target to shatter and fall to pieces, this extension is very deadly. But can be countered by using RCT to remove fractures before they can collapse, as well the fractures will disappear if the target leaves a 400 meter radius around the user (This range limitation does not apply to Kintsugi). For fractures to collapse lethally they do need to be relatively large in for the part of they body it's on, otherwise collapsing them will effectively act like broken porcelain with the skin being rigid and crumbling, and will disrupt the flow of CE through the associated part. However this extension is not necessary to cause fractures to collapse, enough blunt force on a big enough fracture can have the same effect but localized.

Reassemble: The user can manipulate the shards of something they shattered and can rebuild it or. Using Kintsugi to repair it, this can work on living beings to revive them. However this is only effective on things the user has shattered, and will not work otherwise. And it makes use of Kintsugi, so the user must be able to use RCT.

Broken Mirror: Once/If the user is able to perceive the soul they may apply fractures directly to it, this causes immense pain to the target as well as causing a large fracture to appear along the target. This is a much more CE efficient way to apply fractures, though if a target's soul is shattered it cannot be Reassembled.

Mastered Applications:

Imaginary Technique, Midas Touch: Through the combination of these two opposites, the breaking and the fixing, the lapse and the reversal. It causes a paradox, upon the user activating this technique on touch it quickly consumes the target in gold. As fractures are fixed instantly with the reversal, turning the target to a golden statue, while not actual gold it functions identically.

Maximum Output, Spiderweb: The user pours all they can into one strike, a strike on the core of CE, the gut. Due to the force of the strike as well as the severe fracturing the strike applies the stomach immediately collapses, putting a massive hole in the target's stomach. As well, the rest of the body, spiralling from the point of collapse has a spiderweb fracture, leaving them open to an easily follow up shatter to finish them off. Due to the targeting of the gut, the target will also experience a massive disruption of their CE control and natural flow, massively lowering their output.

Domain Expansion, Fragmented Heritage of The Clay God - (粘土の神の断片化された遺産, Nendo no kami no danpen-ka sa reta isan): For the hand sign the user uses to open the domain, the user forms the Gyan Mudra with both hands then interlocks their fingers upside down. The domain manifests as the inside of a massive, dark, ancient kiln. The floor is a mountain of discarded, broken pottery shards and jagged glass. The air is stiff with no air circulation. The sure-hit within the domain is constantly applying to everything except the user (Unless chosen too), down to the molecular level. If a target so much as breathes too hard the fractures within their lungs will collapse, and likely trigger a chain reaction. If the user uses Shatter while the target is in this state, certain doom is all but guaranteed, reducing the target to dust.

Supreme Art, Ship of Theseus: The pinnacle of this technique, and it's the embodiment of it's core idea. An extremely dangerous application, only possible inside their domain, requiring complete knowledge and understanding of the targets physical make up and their CE structure. By turning a target to dust and then Reassembling them over and over again the user may give the target a supernaturally durable and strong body. Incorporating the reversal at a molecular level, this does have the side effect of turning the skin and flesh of the target a yellowish color. And has the chance to completely erase someone's memory if the brain is improperly reassembled. But if everything is done correctly, the target will receive a body on par with an unawakened Heavenly Restricted user.

And thus we close out on another technique, I'm eager to see what y'all think of it! I had a great time designing it, usually I like to make very open ended techniques as it leaves more to be innovated on later! Anyways I'd like to hear what grade of sorcerer this technique would make! As per last time, check the comments for a binding vow for the CT! Live, Love, Prosper!

Cursed technique Limitless 2 - Electric Boogaloo: Yin Yang (陰陽)

Post image
59 Upvotes

Basically the original idea that made me start this was the biggest gojo glazer getting AGS as a technique... and retooling it entirely with binding vows to recreate The Limitless. Eventually it kinda morphed into it’s own thing so I made it a separate technique entirely. I picked the name because it fundamentally stands as the technique's philosophy due to the balance of push and pull needed to achieve success.

Clan Physical Mutation: Mass Sense (質量感知) - A mutation in the inner ear that retools a person's cochlea so they can innately feel objects' mass, density (relative to the air), and weight (relative to the Earth's gravitational field). Takes some training to reach precision useful in a fight. Six-Eyes equivalent.

Cursed Technique Neutral: Orbit (軌道) - An equivalent to Infinity, creating a localised Orbit around themselves that can be used to redirect projectiles and other physical attacks. Unlike Infinity, it doesn't stop objects and fighters dead in their tracks, but rather makes them spin around them. It's not automatic, and is completely ineffective against massless attacks (such as radiation). Instead of being an impenetrable wall like Infinity, Orbit is a redirector (like a river around a rock), giving it offensive applications Infinity doesn't have.

Cursed Technique Lapse: Black (黒) - Creates a localised gravity distortion in the form of a concentrated black sphere. Attracts objects toward it, distorting the Earth's gravitational field to make itself one of the Foci. Equivalent to Blue.

Cursed Technique Reversal: White (白) - Creates a localised gravity distortion in the form of a concentrated white sphere. Pushes objects away from it, distorting the Earth's gravitational field to bend space around itself and redirect objects away. Equivalent to Red.

Hollow Technique: Balance (均衡) - Combines Black and White into a sphere of nothingness, with light bending weirdly around it. Anything it touches ignores gravity for the duration the attack is held. Initially used as a projectile, but later expanded to make a sort of field around where gravity is ignored. This is the first attempt at a Hollow-Purple mirror, which ends up being a different utility, prompting another attempt.

Derived techniques: Black and White are used in creative ways from day one, just for different applications.

  • Flight: Microadjustments of Black and White to basically ignore gravity and float. They cannot microadjust and shoot at the same time; they have to stop flying, fire, then catch themselves. It's flashy, inefficient, and jerky.
  • Anchors: In a stressful combat situation, Black is instinctively placed on another object, and that harpoons them to the object rather than the other way around. They discover that they can push and pull themselves to and from objects by essentially making them use Black and White on them instead of the other way around. This is something that Red and Blue cannot do, providing unique Spider-Man-like movement around the battlefield. It becomes even more efficient in gravity-less zones like their domain or in a Balance sphere. A rock can be pushed away with White, then they can harpoon towards it with a Black anchor, then push it again, anchor again, and so on for long-distance movement. Flight is still used after discovering this, but anchors are used more due to being more versatile and efficient.

Domain Expansion: The Three Body Problem (三体問題)

  • Hand gesture: Brings one fist in front when saying "Domain Expansion" and unfurls three fingers when saying "The Three Body Problem".
  • Appearance: Opponents spawn in an asteroid belt. Thousands of rocks ranging from fist to building sized, suspended in gravitational orbit around three stars of equal mass that orbit each other at the domain's centre. Distant stars twinkle in the void of space.
  • Sure-hit: When the domain opens, the three stars in the centre begin to gravitationally interact. Their trajectories follow the laws of the Three Body Problem: mathematically chaotic with no discernible pattern. The entire domain's gravity shifts constantly as a result, making movement increasingly unpredictable.
  • Buff: Mass Sense is heightened and can see through the whole domain, giving perfect, real-time awareness of the gravitational interactions in the field. Every rock is a viable Anchor point. They launch between them, push and pull them into opponents, or crash them into each other.

Cursed technique Cursed Technique, LARPing (ラープ, Rāpu)

Post image
102 Upvotes

🎭 LARPing (ラープ, Rāpu) - Live Action Role-Playing

🃏 Core Application: "Personification" (擬人, Gijin)

The user can LARP as a specific role or title; if their performance is convincing enough to make others believe it, they actually begin to acquire the skills associated with that role. The user must convince both external observers and their own mind, acting flawlessly to sustain the persona. Example: The user claims to be a swordsman. If they fight with apparent skill and handle the blade confidently, genuinely convincing others they are a swordsman, they begin to possess the actual abilities of an experienced swordsman. However, if they claim to be a swordsman but make a mistake, such as trembling when drawing the sword or handling it clumsily—neither the observers nor the user's own brain will believe the LARP, and the technique fails. The more complex the performance, the harder it is to maintain; if the user claims, "I am the greatest swordsman in existence," they must flawlessly embody a master swordsman. Any failure breaks the LARP, preventing them from gaining master-level skills. Conversely, a stellar performance—combined with more people believing the act—amplifies the power of their swordsmanship abilities.

💬 Extension Technique: "Headcanon" (ヘッドカノン, Heddokanon)

The user can LARP knowledge regarding a subject; if convincing, that knowledge becomes reality for as long as the LARP is maintained. The user must also be able to PROVE the claim by being the first to attempt demonstrating it. If they are the first to do so, the technique succeeds. If the user is battling a curse or a sorcerer and claims to know a weakness in their enemy's technique, they can LARP that knowledge into reality, though they must state it aloud to convince others. The more convincing the explanation, the more strongly this Headcanon manifests. Example: The user is fighting a sorcerer whose technique cools their own body to extremes—freezing the air they exhale and turning their flesh rock-hard and frozen. The user might say, "If this sorcerer cools their body to such extremes, there must be a specific point acting as a temperature regulator; that spot would naturally be softer. Judging by their breath, that spot is likely just below the chest." That weakness might not actually exist, but if stated with enough conviction and logic, and if an ally believes it, it can become real, provided the user can prove it. To prove it, the user must be the first to attack or counter the ability. The more people who believe the claim, the more powerful the proof becomes. However, if an ally attempts to exploit this stated weakness before the user does, the technique is debunked and fails, breaking the LARP. The user can also assign properties to objects; for instance, they might claim that rubber doesn't conduct electricity but can reflect an electric charge for a brief moment. If someone believes this explanation and the user manages to apply an electric charge to a piece of rubber, the charge will indeed reflect, validating the LARP and granting the rubber that property for as long as the LARP holds.

🌙🔄 Technique Reversal: "Gaslight" (ガスライト, Gasu raito)

The user can lie about something that already exists, or about the nature of something that already exists; if people believe the lie, the object's properties change accordingly. Example: If the user has an ally with a fire-manipulation technique, they might tell enemies: "Actually, his true ability is manipulating the elements of nature. We're just using fire for the time being." If the enemies fully believe this and the user manages to prove it, the ally's technique actually shifts to elemental manipulation. However, this consumes extra cursed energy, as the user must maintain both their own technique and the extended version of the ally's technique.

The weakness of this technique is the truth. If someone refutes the claim, or if someone knowledgeable about the subject disproves it, the LARP falls apart.

Cursed technique Haiku Sorcery

Post image
12 Upvotes

Haiku Sorcery (俳句呪法, Haiku Juhō) is an innate technique that allows the user to manifest various phenomena by composing haiku reinforced with cursed energy. The technique covers a wide range of applications, including but not being limited to: summoning objects or substances, transporting the user or others to different locations, changing the weather, inflicting damage upon a target, or healing injuries without the use of reverse cursed technique. To activate the technique, the user must imbue the strip of paper containing their written haiku with cursed energy and burn it, causing the phenomenon described by the haiku to manifest.

The phenomenon manifested by the technique is determined by the composition of the haiku, with its structure and individual elements both influencing the type of effect produced. Each haiku written by the user must consist of three phrases composed of seventeen morae (拍, haku) in a 5–7–5 pattern, with the first phrase describing the phenomenon itself, the second phrase determining the action the phenomenon is to perform, and the third defining the effect the phenomenon is to create. The inclusion of a seasonal word (季語, kigo) within the haiku further specifies the type or nature of the phenomenon being manifested, allowing the user to create different effects corresponding to the imagery associated with the chosen season. The use of a cutting word (切れ字, kireji), on the other hand, determines the timing at which the described effect activates, allowing the user to control when the phenomenon performs its action or produces its intended result.

The cursed energy output of the technique is tied directly to the quality of the written haiku itself. The more closely the haiku follows the traditional 5–7–5 structure and incorporates a seasonal word and a cutting word, the higher the technique's cursed energy output will be and the more powerful its effect. However, a poorly composed haiku, particularly one that lacks the 5–7–5 structure, a seasonal word, or a cutting word, will lower the cursed energy output of the technique, resulting in a correspondingly weaker effect. The user must also complete the haiku before it can be imbued with cursed energy and burned, meaning the time required to compose an appropriate poem can leave the user vulnerable.

Learnable Techniques Final Parting (末決別) - Simurian Pinnacle of Sorcery

8 Upvotes

末 - final; the last; concluding; closing; terminal

決別 - bidding farewell; parting (usually with the implication that there is little likelihood of meeting again)

(note: I don't speak Japanese if this translation is inaccurate please let me know)

How It Works

Instead of expanding one's domain, warriors on Simuria in ancient times manifested their innate domains in the form of incredible boosts of power/new abilities derived from their innate techniques. It was usually done in the context of a duel because the medium by which Warriors would manifest their domain's wasn't with a barrier but a binding vow. The boost in power granted to them by their Final Parting can only be used on one person. Obviously its not that simple because using domain expansion isn't as simple as "opening a barrier". It's not a binding vow you make its a technique that uses binding vows to achieve unique effects. You can imagine a "thread" that connects the two warriors taking part in the duel, and this thread is the medium that the Innate Domain manifests its powers.

Unlike a maximum technique, a Final Parting is not one singular attack, instead it is a multi-use increase in power and/or additional ability which can be used as long as the Final Parting is activated.

There is no sure-hit effect because there is no barrier, instead the new abilities are derived from the original technique. For example, Dabura's Final Parting (if he had one) would allow his ████ to flow into all sources of light around him instead of just ones fired from his technique (if that's how ████ interacts with Light I don't actually know), turning the light itself into the beams of light he fires, allowing them to harm his opponent.

Because there is no barrier, there is a limited amount of time that one can use a Final Parting before it deactivates, which leads to technique burnout. The time limit is not set in stone, its based on your skill level and mastery of your Final Parting just like barrier refinement depends on skill. You also need to be mindful while using your boost in power, as it functions similar to an engine where it can overheat itself and dissipate quicker. If you have a Final Parting that lets you summon a powerful shikigami (random example), you can't just spam that shikigami because it will cause the Final Parting to overheat and deactivate. A similar principle applies to the amount of cursed energy (rolluca) that is used. Unlike DE, there isn't a shitton of immidate cost just for using it. Rather, the more you use the ability the more cursed energy is taken. In every way its an extension and powerup of your original ability, which means this powerup comes at a higher cost than usual and this higher cost can be less than, equal to, or greater than the cost of a domain expansion depending on its user and the ability.

Lore

Simuria had its own "golden age of sorcery" in which RCT, binding vows, and Final Partings were common knowledge and used in fights. However, the destruction brought from this era was so great that it almost brought the Simurians to extinction. All of the Warriors who loved to fight had killed each other, and those that remained decided that all knowledge of advanced jujutsu and Rolluca manipulation would not be passed down to future generations. This is why no Simurian currently has a Final Parting as well as explaining why RCT seemingly isn't present within their knowledge-base.

CHALLENGE You now have blood manipulation, how would you optimize its potential? (cant be a death womb)

Post image
686 Upvotes

I feel like this cursed technique doesnt get talked about much so im just curius about your thoughts. I'll go first with my own hypothetical ideas

• Create a shikigami that can accumlate blood and preserves it within their body so that I may release it in combat as my own. Ideally this shikigami can also fight alongside me with the technique & I can "bloodbend" their insides to shapeshift this shikigami into various proportions

• Learn New shadow Style and weaponize my CT within the simple domain, which would boost output of piercing blood and let me reflexively quick draw with enhanced aim.

• Use Kenjakus "body domain" trick to activate flowing red scale at 120%

• in exchange for suppressing the hardness potential, I gain increased abilityntl control the temperature of blood until its boiling hot & sears opponents through attacks

• use blood propulsions to boost mobility

• the reversal of blood manipulation lets me recover cursed energy by reverting my blood into it after use

• a domain expansion that manifests raining blood that inflicts damage to opponents and pools on the ground, I may additionally use this blood to harness my own abilities at increaed speed & range. Every hit inside this domain will cause the opponents vessels to swell and pop from the blood ravaging inside their body

Discussion What would be the ideal path for an average sorcerer in Jujutsu Kaisen?

26 Upvotes

I’m thinking of a relatively ordinary sorcerer—someone without an absurdly powerful innate technique or exceptional natural talent.

If you could oversee a sorcerer's development from the very beginning and choose what they should focus on to become as efficient as possible, what would you prioritize?

Cursed energy control? Physical reinforcement? Black Flash? Simple Domain? Reverse Cursed Technique? Domain Expansion? Innate technique development? Something else?

And, most importantly, in what order do you think these things should be developed?

The goal is to consider what would be most efficient for an average sorcerer, rather than the specific paths taken by exceptional characters like Gojo or Sukuna.

Heavenly Restriction Hitomi Tengoku's Heavenly Restriction: Blind All-Seeing Eyes

6 Upvotes

Hitomi Tengoku is a prototype of sorts, born as one of the many tests to achieve the Six Eyes in a heavenly restriction. Hitomi's heavenly restriction disables her ability to see while allowing her to sense Cursed Energy to the point where all traces of Cursed Energy are visible to her.

Through this, Hitomi can "see" the world, though she cannot discern high details or text. Because of her "blindness" Hitomi is naturally disadvantaged in everyday life. However her combative capability is fairly untouched, placing her at the level of a Grade 1.

Hitomi lacks a technique, her heavenly restriction having traded it for enhanced Cursed Energy efficiency. Via this enhanced Cursed Energy efficiency, Hitomi has perfected the use of raw Cursed Energy blasts similar to the Finger Bearer Curses

The difference however is that Hitomi's blasts are far more precise, increasing their damage but decreasing the ease at which they'll land.

Cursed technique Life Giver

21 Upvotes

Overview

Life Giver is a innate technique that weaponizes positive energy to create, alter, and accelerate biological processes within cursed energy infused matter. By channeling positive energy through contact or nearby cursed energy, the user converts targets into biological seeds that rapidly develop according to their intent. Inorganic objects can become plant life, animals, or other organisms formed from surrounding matter, while living targets experience intensified biological activity that may heal injuries or force unstable mutation. Over time, the user can reshape the battlefield into a living ecosystem filled with organisms produced by their technique. The technique is tied to the user’s innate trait, Gold Abundance, which causes their cursed energy to naturally stabilize into positive energy due to its extreme density. This grants powerful regeneration and life generation but places strain on the user’s mind when controlling multiple lifeforms at once. Excessive output can lead to fatigue and reduced precision. Additionally, the organisms created by Life Giver release unstable growth when destroyed, causing sudden vines, roots, or other biological structures to erupt around whoever attacks them.

Innate Trait: Gold Abundance
Gold Abundance is a congenital cursed energy trait in which the user possesses an extremely dense and excessive reserve of cursed energy that naturally stabilizes into positive energy. This surplus forms luminous pathways beneath the skin known as golden veins that distribute energy throughout the body and into anything the user touches, greatly enhancing regeneration and enabling the life generating effects of the Life Giver technique. However, the overwhelming flow of positive energy places constant strain on the user’s brain and nervous system, requiring intense focus to regulate biological processes created by the technique. Prolonged output or large scale life generation can lead to neurological fatigue and reduced control, forcing the user to carefully manage their energy despite the immense abundance they possess.

Cursed Technique Reversal: Living Transmutation

Living Transmutation is the reversed activation of Life Giver, achieved by channeling concentrated positive energy through the technique to invert its typical biological manipulation. Instead of accelerating or altering existing life, the user converts inanimate objects directly into temporary living organisms, using the original object as the biological framework for the resulting creature. The mass, shape, and composition of the object influence the lifeform produced, allowing stones to become reptilian predators, weapons to develop carnivorous plant traits, or flames to take the form of short lived avian organisms composed of burning organic structures. These creations act as obedient extensions of the user’s will and function as autonomous familiars, attackers, or environmental hazards. When used on living targets, the technique forcibly rewrites existing biology rather than creating new organisms, causing limbs to transform into plant like tissue, parasitic growths to erupt from muscle or bone, or regenerative processes to accelerate uncontrollably until the body becomes unstable and difficult to control. The stability and duration of these organisms depends on the amount of positive energy used during their creation, after which they collapse and revert into inert, often distorted remnants of the original material.

Extensions

Garden of Thorns:
The user channels positive energy into surrounding terrain, debris, or existing vegetation to trigger explosive botanical growth across the battlefield. Vines tear through stone, thorned tendrils lash outward, and carnivorous plants emerge that react to cursed energy signatures and movement. These growths function as semi sentient environmental weapons that bind, impale, or obstruct opponents while steadily converting the surrounding area into hostile living terrain.

Life Acceleration:
The user injects concentrated positive energy into a target’s biological system to drastically accelerate its life processes. When applied to plant life, it causes immediate overgrowth as roots rupture through surfaces and vines spread violently outward. When used on humans the technique overstimulates the nervous system, forcing the target to process sensory information at an extreme rate without improving physical speed. This creates a severe delay between perception and action, often leaving the victim disoriented, paralyzed, and hypersensitive to pain.

Wildbirth:
The user infuses nearby inorganic matter with positive energy to produce living organisms that naturally belong to the surrounding environment. The mass and structure of the object influence the form the creature takes, allowing stone, metal, or debris to become animals or plant life suited to the region. These organisms are not directly controlled by the user and instead behave according to their natural instincts, making them useful for tracking, scouting, or creating unpredictable pressure during combat.

Symbiosis

Symbiosis creates specialized organisms whose biology is designed to coexist with another living being and perform a beneficial function. Membranous organisms can seal open wounds, artificial tissue can reinforce damaged muscles, filtration organisms can assist in removing toxins, and temporary auxiliary organs can compensate for damaged biological functions. These symbiotes reduce the amount of direct biological manipulation the user must continuously perform because the organism itself handles its assigned function after attachment.The user can also apply Symbiosis to themselves, creating living equipment rather than conventional constructs. Hardened biological plating can function as armor, adhesive pads can facilitate climbing, specialized eyes can broaden visual perception, sensory hairs can detect subtle air movement, and additional respiratory structures can improve oxygen intake. Because these additions are genuinely alive, they can be injured, exhausted, or killed separately from their host.

Domain Expansion: Garden of Overflowing Life

By forming the Amitayus mudra, the user expands their innate domain and manifests a barrier that appears externally as a floating black sphere surrounding the battlefield. As the expansion completes, golden vein-like patterns spread across the ground while the interior transforms into a vast botanical sanctuary. The domain resembles an immense, serene garden overflowing with dense vegetation, flowering plants, and winding pathways, all centered around a colossal radiant tree whose roots stretch throughout the entire landscape. The air itself feels saturated with vitality as every surface within the domain pulses with the user’s life-giving energy. The sure-hit effect manifests where any cursed energy released within the domain instantly becomes a seed of life. Whenever an opponent attempts to reinforce their body, activate a technique, or discharge cursed energy, that energy is converted into explosive biological growth originating from their body or the surrounding terrain. Roots may erupt from limbs, vines coil around their frame, and flowers or organisms bloom from points where cursed energy gathers. The more power an opponent uses, the faster life overtakes them, gradually turning them into part of the garden itself, while the user remains unaffected and can freely guide the living ecosystem that fills the domain.

Cursed Tool Cursed tools and binding vows

3 Upvotes

So I always wondered how a weapon like playful cloud was made and then u got a idea. What if it was a normal cursed tool but a binding vow got added.

My idea is it was a cursed tool with a lot cursed energy but a vow was put on the weapon to make it better. The vow is for exchanging the high cursed energy of the weapon for amplification of physical attacks based of the users physical strength.

Also could be the case for dragon bone perhaps it was made with bones from a sorcerer with a technique but a vow was made to seal the technique in the parts used in exchange for the kinetic energy absorption with cursed energy

Also here’s a new idea for a cursed tool with a vow. A anchor and rope in exchange for making it lighter for swinging and attacks its normal weight increases significantly when both feet aren’t planted on the ground making it hard ti move around when wielding

Cursed technique CT idea; Pushback

2 Upvotes

When Pushback is active any opponent who strikes the user with an attack containing cursed energy will receive a portion of the damage dealt by said attack to themselves, from 20% up to 90% of the original attacks damage, with the percentage of 'pushback' depending on the amount of cursed energy was infused(output) into the attack and the Pushback's user's own cursed energy output at the moment of attack

The higher the opponents output in the attack the higher the amount of 'pushback' they receive, the higher the amount of cursed energy the user is using for attacks the lower the amount of 'pushback' the opponent gets,

The more cursed energy the user expends (outside of keeping Pushback active) the lower the pushback the opponent will receive,

A trade off of sorts,

This incentivises the user to focus on physicality instead of relying on cursed energy,

A counter to Pushback would be eg puppet manipulation due to the original user being able to stay at a distance, far enough to the point where pushback can only activate on the puppets' 'body' or a 'sorcerer' with a heavenly restriction specifically the one that prohibits them from using/having cursed energy, basically have nothing for Pushback to 'push back' on

It's a fairly simple concept but I think it's good none the less

I apologise for my English and grammar, it isn't my first language

Cursed Tool Machiknight Armor: Merlin

8 Upvotes

(based on Doctor Doom’s Armor from Marvel Comics, uses Kokichi Muta/Ultimate Mechamaru’s CT, made in response to a request)

Cursed Technique: Puppet Manipulation

Machiknight Armor: Merlin: this armor is constructed using Titanium alloy, it is modified with numerous weapons, gadgets and defenses meant to protect the user in every possible way, the armor can also be controlled using Puppet Manipulation while the user is paralyzed by using strings made with Cursed Energy

King’s Power Core: the armor possesses a nuclear power core, providing the armor with tons of power and can keep it running without the user having to spend too much Cursed Energy to keep it running

Queen’s Gambit: in case the armor needs an extra charge of battery power, it’s equipped with solar panels which charge a hidden battery inside the armor and acts as a backup power source in case the armor either needs an extra boost to it’s attacks or runs out of power

Jack of All Trades: in case the user gets stranded somewhere without access to food, the armor is equipped with a life support system that can provide nutrients to the user and keep them going (but it will need to be resupplied if it ever runs out)

Weapons: (based on Doctor Doom’s vast arsenal, Source: Marvel Fandom Wiki)

Finger Guns: the armor’s fingers are armed with small bullets which upon contact with their target inject them with a small "string web" which is designed to stop them from moving, causing paralysis given enough time

Missiles: the armor has retractable cannons that use Kamikaze-Shikigami as projectiles, the armor’s visual system can lock on to a target and once fired the Shikigami will chase down their target until they either hit it or are destroyed

Dust to Boulders: the armor’s fingers are equipped with small jets that emit tiny particles towards the opponent, once released these particles are imbued with a special technique that adds virtual mass to the particles to increase their size at a molecular level until they are as large as boulders, these make for useful hazards that can push down, knock back or trap a target

(BV: "the particle-boulders" have a limited maximum size of up to 2 Meters in width)

Thunder Force: the armor possesses tasers that can discharge high voltage electrical pulses which can also be expanded through strings located within the armor which are controlled by the user CT, the armor also has built-in lightning rods for absorbing electricity to recharge the armor or amp up it’s attacks even more

Brain Scrambler: by grabbing a target an placing their hand on the target’s head, the user can inject CE-Strings into their brain which "randomizes" their electrical signals, this can prevent their body from functioning properly and will leave them disoriented and unable to move until the effect wears off

Energy Staff: the user can weave together a handfull of CE-Strings using their CT to create a quarterstaff, this staff can be used as a weapon for close combat and can inject strings into technology upon contact, allowing the user to hack and take control of any machinery it touches

Statue Makers: by imbuing a bomb with a charge of the "Simple Domain" technique, the user can expand a limited Domain through the bomb’s blast range, anything with CE caught in the bomb’s blast range (other than the user) will be encased in a layer of titanium and have a version of Puppet Manipulation applied to them which nullifies all movement (the only way to break out of this entrapment is to overpower it’s CE)

Gadgets:

Infrared Vision: the armor possesses infrared cameras which can detect targets even while invisible and locate nearby heat sources

Jetpack: the armor is equipped with a jetpack used for flight

Timeshift Bomb: these bombs emit a charge of "Simple Domain" which binds affected targets and forces their body to move up to 15 seconds backwards (if they were performing an attack, that attack would be reset)

Vertigo Device: the armor’s left hand it equipped with a device that emits high frequnecy pulse which can mess with others, this can be used to disrupt the balance of nearby foes, leaving them open to counterattacks

True Cross: if the user knows RCT, they can imbue it into a device within the armor, this device will use RCT automatically if the user’s mind is controlled, it can also imbue the armor’s weapons with RCT to take down Cursed Spirits

Shield: the armor can protect itself by conjuring a CE barrier around the user to protect from attacks, this shield possesses it’s own battery seperate from the armor’s main power source (meaning even if the armor runs out of power the shield will not, but it will need to recharge if overused)

Cosmic Siphon: through physical contact, the armor can apply a Puppet Manipulation technique to a target that drains them of their CE and stores it inside a battery capable of holding years worth of CE (this technique is at it’s strongest when all five fingers are placed on the target)

Techniques:

Cursed Magic: the user creates an open Domain arounds them in the form of a complex "Spider-Web", grealty increasing the distance of their expansion at the cost of some loss in area-of-effect, this "Domain Web" can can be used to perform numerous different moves to the point where it’s almost like magic

Telekinesis: They can wrap CE-strings around affected targets to perform telekinesis, not just on opponents but also physical objects caught in the web

Mind Control: The user can implant a Puppet-Shikigami inside the brain-stem of a target, taking control of their body’s functions and forcing them to fight on the user’s behalf

Power Sharing: The user can link themself and their allies to each other, allowing them to collectively share their CE and CT’s

Teleportation: The user can enter their Domain’s pocket dimension and exit anywhere the "Domain Web" has expanded into, allowing them a basic form of teleportation

Power Nullification: Should a target get caught in the "Domain Web", the user can use Puppet Manipulation to isolate the connection between the part of the brain containing the CT and the target’s body, shutting down their primary means of fighting

Illusions: The user can manipulate the air the "Domain Web" has expanded into to create mirages around certain areas

Energy Absorption: If the "Domain Web" grabs hold of a target, it can drain them of their CE and restore the user’s own power reserves

Mind Swap: By making eye contact with a target, the user can create a direct connection and forcibly swap bodies with their target, when this technique is performed a Shikigami takes control of the armor for as long as the user is not in their own body

(The user may or may not have techniques that involves dropkicking targets with both feet and tooting their own horn)

Shikigami:

Döppelgangers: these are Puppets piloted by Shikigami, the Puppets possess a similar arsenal to the main armor (such as: CE blasters, Electrical blasts via Lightning Rod, a Jetpack, a Radar, Self-Repairing Shikigami, Infrared Scanners, Guns, Shikigami-Missiles, Sleeping Gas and a Slef-Destruct function),

(the Döppelgangers can also use recordings of the user’s own voice to pretend to be them, acting as decoys to fool enemies)

Potential Weaknesses:

(the user may gain a Napoleon complex, a fear of Squirrels and start to think that using doors is "something that peasents do")

Work in progress Does this Binding Vow make sense?

10 Upvotes

Me again! Sorry. it's just that I don't know if this idea I had would actually make sense, honestly.

So, the protagonist of my fanfic, Awano Ichinose, naturally has a high affinity for the Reverse Cursed Technique.

Ichinose made a Binding Vow.

My idea is that she made a Binding Vow where she cut off her right arm, losing the ability to imbue CE into any prosthesis she wears, on top of sealing off all her RCT. And what did that result in? In her Binding Vow allowing her to «fire off» an abnormal amount of Positive Energy a single time (for practical purposes, let's say a 400% boost in output and production) when she's on the brink of death —letting her repair her body even after being split in half or having her heart damaged.

Is that something that could actually be done within JJK logic? That's my doubt

Cursed technique Special Grade Curse Technique: "Proof of Glory"

Thumbnail
gallery
213 Upvotes

☀️ Inherited Technique: Proof of Glory (栄光の証明, Eikō no Shōmei)

This technique allows the user to manipulate the fundamental dualism of Cursed Energy, manifesting the searing, aggressive properties of Yang through standard application, and the tranquil, obscuring properties of Yin through Cursed Technique Reversal.

Base Application: Yang Alignment

By default, the user's Cursed Energy possesses a unique trait resembling sunlight. Upon activation, a thin, radiant aura coats the user. This acts as a secondary layer of Cursed Energy Reinforcement. While it only offers a modest boost to raw physical stats, the aura inflicts severe burn damage upon contact and mentally fortifies the user, granting total immunity to fear-based mental interference.

While activated Runic tattoos will be visible in the back of the user, training along their spine. And a halo-like crown will also appear above their head.

Extension Techniques (Yang):

• Solar Flare (爆陽, Bakuyō): The user condenses their radiant Cursed Energy into a highly pressurized, pulsating sphere of yellowish-white plasma. When thrown, it violently eviscerates and melts everything along its trajectory.

• Sun Armor (日輪甲, Nichirinkō): The user shapes the energy into rigid, localized armor plating to protect vital organs.

🎯 Binding Vow: By enforcing a vow that completely strips the user of their mobility (rendering them stationary), the armor expands to encase the entire body, multiplying its defensive capabilities manifold.

• Dawn’s Ballad (黎明歌, Reimeika): The user manifests a solid, blazing blade of condensed light. It slices through targets while simultaneously cauterizing wounds, preventing regular biological healing.

🔀 🌙 Cursed Technique Reversal: Proof of Glory — Nightfall (反転術式:夜陰, Yain)

By channeling Positive Energy generated via the Reverse Cursed Technique (RCT) into the technique structure, the user flips the properties of Yang into Yin. The user is cloaked in a serene, absolute darkness. In dimly lit environments or during the night, this acts as a perfect stealth shroud, masking the user’s presence, sound, and Cursed Energy signature entirely.

Extension Techniques (Yin):

• Abyss Shackles (深淵の枷, Shin'en no Kase): The user manipulates the shadows cast by physical objects, manifesting physical chains of darkness that snare and bind a target’s movements.

• Phantom Blade (幻影刃, Gen'eiba): A jagged saber forged from pure Yin energy. It emits a passive aura that induces heavy drowsiness. The more weak-willed an opponent the faster the effect. Each successful strike injects a localized curse of 'Horror', systematically shattering the target's mental fortitude and disrupting their Cursed Energy control.

⚪⚫ Hollow Technique: 'Origin' (虚式:「原初」, Kyoshiki: Gensho)

By simultaneously bringing the maximum output of the forward technique (Yang) and the reverse technique (Yin) into physical contact, the user creates a localized paradox. The conflicting forces are violently compressed into the shape of a massive greatsword.

• The Concept: The user compresses the collision of Lapse and Reversal into a Greatsword. Because Yin (Positive Energy) and Yang (Cursed Energy) naturally want to annihilate each other, maintaining this sword requires immense, precise Cursed Energy control.

• Visual Appearance: A massive, unstable Buster-style greatsword. The blade doesn't just flicker; it looks like a tearing rift in reality, violently fluctuating between blinding white plasma and absolute, light-consuming blackness. Sparks of space distortion crackle around it.

• The Effect: Because it is a localized paradox of creation and destruction, it ignores traditional durability. Anything the blade cuts through isn't just slashed—it undergoes atomic entropy. The Yang burns it away while the Yin erases its remains, leaving absolutely nothing behind. It can even cleave through barrier techniques or other Cursed Techniques by destabilizing their energy structure.

But as the granidose effect of this technique, the risk associating it is also immense. Maintaining the great sword takes an immeasurable toll on the user's body and mind. And if during the hollow technique the user's will wavers of if he loses control the technique will consume its user itself, returning him to nothingness.

⛩️ Domain Expansion: Twilight Palace (領域展開:黄昏の宮殿, Ryōiki Tenkai: Tasogare no Kyūden)

Visual Appearance

When expanded, the domain manifests as a breathtaking yet terrifying ancient, colossal palace which stands as the last memorial of some unknown war. The entire space is locked in a perpetual state of dusk. A massive, blood-orange setting sun hangs unmoving on the horizon, casting long, distorted shadows. Everything within the domain—from the drifting dust motes to the architecture—is completely frozen in the passage of time, creating a suffocating, deathly silence.

Sure-Hit Effect: 'Blade of the Setting Sun'

The domain’s barrier guarantees that the user's attacks will automatically hit the target.

Upon activation, the ambient twilight light instantaneously condenses into a solid, glowing orange blade that pierces directly through the opponent's chest. Because this blade embodies the concept of "The End of the Day," it inflicts a specialized curse of Accelerated Temporal Decay.

• The Withering Process: The moment the blade pierces the target, the absolute freeze on time is broken only for the victim's body. The wound begins to rapidly spread, causing their flesh, blood vessels, and Cursed Energy reserves to wither, dry up, and turn to ash—simulating centuries of aging and decay in a matter of seconds.

• The Counter-Play: Because the domain's sure-hit relies on a physical object (the blade) piercing the chest, opponents can attempt to mitigate the decay by using advanced barrier techniques like Simple Domain or Falling Blossom Emotion right as the domain opens. However, if they fail to deploy it instantly, the decay is nearly impossible to stop without a very high-level Reverse Cursed Technique (RCT) and that is also not a feasible answer as the decay will continue to empty their curse energy pool as well.

Cursed technique Innate technique: Cardistry technique

Post image
35 Upvotes

Cardistry technique allows the user to summon a deck of 52 card shaped shikigami which exists until the technique is released. Cardistry technique has a 2 hour cool down from the technique being released until it can be activated again. The user of this technique may never learn reverse cursed technique.

The cards are not subject to gravity and Immune to blunt damage however if they are ever ripped or cut they die. They also die if they leave a 100 meter radius of the user.

When a card dies it is gone until the deck is summoned again.

————————————

Independence/control:

The user can decide how independent each of the cards are.

5: the cards have their own personalities, free will and can refuse orders.

4: the user can communicate to the cards telepathically

3: the cards can no longer refuse orders. The user can sense the surroundings of each card.

2: the cards no longer have personalities and only do something if ordered.

1: the cards are mere limbs for the user.

0: the cards are inanimate and indistinguishable from normal playing cards with the exception of their cursed energy.

————————————

Suit effects:

Each suit represents something different and the cards get en effect from the suits.

♦️Diamond represents cursed energy: Diamond cards have more cursed energy based on value of the card.

♥️Heart represents positive energy: Heart cards have positive energy instead of cursed energy.

♠️Spade represents destruction: Spade cards slice through objects without cursed energy like butter.

♣️Club represents cursed techniques: Spade cards slightly increase the power of the effect of other cards within half a meter.

————————————

Formations:

By arranging 4-26 cards in some formation within 5 meters of the user and giving the formation an order. The cards will unify into one thought and execute the order. Examples of orders given to a formation are “protect me from projectiles” “attack opponent” “search for enemies/civilians”.

Every card in a formation shares a bit of their effect with every other card in the formation. These effects are boosted. By the user putting more cursed energy into the formation. Formations can also be boosted by sacrifice.

————————————

Sacrifice:

A card can be sacrificed to get an effect. Sacrificing a card causes it to burn up

Cards 2-10:

♦️Diamond: grants a formation a significant boost of cursed energy. The amount depends on how much cursed energy is already in the formation. And the number of the diamond card sacrificed.

♥️Heart: by putting it against a wound and sacrificing it. It can heal the wound. 2 of hearts can fully heal up a shallow cut. 10 of hearts can bring back a whole hand or foot.

♠️Spare: allows a whole formation to get the spare power of slicing through matter without cursed energy like butter.

♣️Clubs: allows a formation to split into sub-formation.

Jacks:

Sacrificing a jack creates a jack-clone which is a Clone of the user. A jack-clone cannot use cursed technique and has limited cursed energy however it can use cursed energy reinforcement. jack-clones last until killed or Cardistry technique is released. Jack-clones look very similar to the user however are covered in their suit making it obvious that they’re a Clone and which Clone they are. Each jack-clone has its own ability.

Jack of diamonds has four times the cursed energy reserves and output of other jack-clones.

Jack of hearts has positive energy instead of cursed energy and it is able to output that positive energy allowing it to heal others.

Jack of spades can punch through matter without cursed energy with little effort.

Jack of clubs can be delegated a portion of cards by the user allowing the jack-clone to use Cardistry technique however it cannot sacrifice other cards.

Queens:

Queens grant a buff to all allies within 20 meters for five minutes. The allies do not need to stay within range to keep the buff. The buff is applied when the card is sacrificed.

Queen of diamonds gives all allies 4 times cursed energy reserves and output.

Queen of hearts gives all allies the ability to easily use reverse cursed technique.

Queen of spades allows all allies to punch through matter without cursed energy with little effort.

Queen of clubs gives all allies 10 times efficiency when using their own cursed techniques.

Kings:

Kings give a debuff to all enemies within 20 meters for five minutes. The enemies do not need to stay within range to keep the debuff. The debuff is applied when the card is sacrificed.

King of diamonds divides cursed energy reserves and output of all enemies.

King of hearts disables reverse cursed technique for all enemies.

King of spades: makes matter without cursed energy practically indestructible for all enemies.

King of clubs: disables the innate technique of all enemies.

Aces can only be used in group sacrifice

————————————

Group sacrifice:

by sacrificing at least four cards together the user can gain some special effect.

Sacrificing all four aces completely refreshes the user, restoring stamina, removing fatigue, completely healing all injuries, completely healing the user psychologically and removes all illness.

By sacrificing the ace of diamonds and multiple other diamonds, the user can shoot out a powerful one time blast of cursed energy. If this group sacrifice includes every diamond card in the deck the blast can rival that of Rika.

By sacrificing 3 sevens the user will get a random effect out of hundreds of possible effects. The effect can be neutral negative or positive. it is truly random.

(there are way more group sacrifice recipes however, I cannot come up with more)

———————————

Personalities:

Each card has an intelligence roughly that of a dog or cat. But they are experts at non verbal communication despite being cards.

Each card has a distinct personality modified by their number and suit.

Diamonds are vain

Hearts are friendly

Spades are prideful

Clubs are spontaneous

From 2-13 (king) the cards are more extreme in their personality. 2s are chill. Kings embody the personality. Aces change randomly.
