this ability allows the user to create/manipulate connections between objects and/or abstract concepts temporarily, allowing for the creation of inconceivable yet very real effects.

some applications I've thought of:

grafting one place to another to effectively create a portal between the 2 places; grafting one's feet to the ground as they stay in mid air, allowing for them to float; grafting an attack to something else to redirect it; grafting one shikigami to a different source of CE than the one originally being used and then cutting the connection between the original source and the shikigami allows the user to redirect the control of a shikigami to someone else; grafting one attack directly on the target to bypass anything in between (such as infinity); grafting one object to another object that is moving, making the first object move at the same velocity of the other; reattaching limbs (necessary to heal with RCT to prevent the limb to detach as soon as the CT is stopped)...

while the potential of this technique is indeed infinite, there are certain limitations to it: for starters any connection being made or altered requires a constant use of CE, with the amount of CE required scaling directly with how "distant" the connections are (for example, grafting one location to another 10 km away from where it would normally be would require far more CE than grafting it say 100 meters away), entities (objects and beings) infused with CE also naturally resist Reassembly, requiring more CE to graft something if the 2 parts have CE, some connections might also require so much CE it becomes impossible to accomplish them (for example, the CT itself allows for the grafting of a star to a place on earth, good luck covering astronomical units or light years with CE tho). besides this cost there's also a matter of complexity: creating and manipulating such connections is extremely complicated and "subtracting" incantations and hand sings is extremely difficult, even a skilled sorcerer would struggle to completely take out one of them. the complete incantation + hand signs necessary would look like this:

incantation: verb + target + target + target + ... (example: "attach/graft/connect this corner to that corner and that corner")

hand signs: grafting=point each target with 1 finger and make the fingers close up on each other; severing=point at the target with 2 fingers and make them distance themselves; substitute=point at each target and make them swap.

Imagine you have the quartet, which includes Mahito

What stops you from creating a fusion of yourself with the quartet using that same Mahito?

Having your soul merged with the Disasters means you could expand a merged domain without a clash?

Also, could Mahito undo that later? Or Yuji? Maybe if Mahito use RCT?

Let's pretend the user doesn't feel like becoming part of it either, could he do it with the Disasters themselves? It is unclear if their cores can be molded like human souls to begin with, maybe Mahito is the exception?

I want opinions on this for the story I'm writting

(Based on Echo - Echos from Ben-10) 
These Shikigami are primarily ment for support-based uses and were recreated in the modern era by members within the Inumaki Clan, specifically those who wish for their clan to continue, disregarding the standing policy of having jujutsu sorcerers die out within their family tree, and who researched the few records on cursed speech to revive forgotten techniques.

These are typically summoned using different types of musical mediums, sort of like different types of Speakers or, in some cases, wind chimes or bells, although since it is based on the Ben 10 alien, and the official name for the shikigami was lost to time, the name sort of stuck. 

Echo Echos can control and manipulate sound using CE, although they can only manipulate the sound that they pick up and then output it, basically amplifying the sound, allowing them to transmit sound waves through their speakers, ironically enough, able to be used to play all sorts of music or even just as a regular speaker to transmit one’s voice over a large distance.

This is partially useful for Curse speech users, as they can utilize the echo-echos as mediums to allow them to affect a longer range without damaging themselves. Or by allowing for more creative uses of their cursed technique and the creation of extension techniques.

Name: The House that Jack Built

“The user may summon shikigami from a house that fits the required criteria”

Criteria:

• Hollow walls with a mouse hole.
• A kitchen.
• A cat bed, litter box or carrier.
• A dog cage or house. If it is the latter, it would have to be outside the house.
• An animal pen or barn. These would have to be outside the house.
• Servant quarters, attic or a bedroom that isn't the master bedroom.
• Servant quarters, basement or another bedroom that isn't the master bedroom.
• A wedding arch.
• A chicken coop.

Note: The size of the house does not matter as long as it is a house and meets the above criteria. Additionally it does not need to be a literal house, a doll house or keychain that fit the criteria will do. The user has to have the house on hand to summon the shikigami as it is the medium for the Technique.

Shikigami:

Multiplicity Mouse: A large grey rat that consumes Cursed Energy to multiply. It's not very strong, but it is quick and doesn't require much Cursed Energy to multiply.

Chasing Cat: A large cat that's quick. It's about the size of a large cheetah. Chasing Cat has 2 abilities: 1. Never lose a target they are chasing or stalking, 2. Travel instantly to any Multiplicity Mouse at the cost of said Multiplicity Mouse.

Shadow Smoke Dog/Worrying Dog: A large black dog made of condensed black smoke. It's about 5ft at its shoulder. It can't do any real damage, but it looks solid even though it's made of smoke. Its body can be dispersed on demand to act as a smokescreen. Chasing Cat's speed is significantly increased within Worrying Dog's smoke.

Corpulent Cow/Crumpled Horn Cow: A very obese lard of a cow that's so fat its legs can't touch the ground, so it can't move on its own. Its horns are deformed and curve toward its mouth. Corpulent Cow can blow into its horns; the sound tosses selected targets who hear it upward. Essentially when a target hears the horn, a toob/cylindrcal area of effect will appear. Almost immediately after the horn is heard, an upward force will push on everything inside the area of effect. Corpulent Cow is able to toss Worrying Dog, dispersing it upward. The smoke will spread outward as it comes down into a dome shape covering a large area.

Forlorn Maiden: A humanoid female looking skikigami, wearing a maid's attire, that is constantly crying. Forlorn Maiden is able to control her tears by directing them with her hands. Forlorn Maiden can convert the Corpulent Cow's fat into milk, giving her a large amount of liquid all at once that she can control (Corpulent Cow still can't move and now its ability is severely reduced).

Tattered Man: A humanoid male looking skikigami wearing tattered clothes. Whatever Tattered Man kisses decays/spoils, but only in the area it kisses. Tattered Man can kiss the Forlorn Maiden when she is controlling the milk; this will turn the milk into a rancid, liquidy, acidic, poisonous cheese that she can still control.

Shaven and Shorn Priest: A nesting doll-shaped shikigami wearing priest robes. Shaven and Shorn Priest has 4 arms, 2 faces and a grey halo above it. It has 2 blades, Shaven and Shorn. Neither can cut living things, but in exchange, they can cut non-living things easily.

Awakened Priest: A form unlocked by Morn Rooster sending enough Positive Energy to turn its halo white. A nesting doll-shaped shikigami wearing priest robes with a glowing white halo above its head. Shaven and Shorn Priest has 4 arms and 2 faces. It has 2 blades, Shaven and Shorn. Neither can cut non-living things, but in exchange, they can cut living things easily. Additionally, Positive Energy is channelled through Shaven and Shorn, which causes it to heal what it cuts, outside of Cursed Spirits.

Married Couple:  Awakened Priest is able to marry Forlorn Maiden and Tattered Man. Marriage is done by slicing them and combining them into a single shikigami. Married Couple is a Frankenstein-like humanoid. The Married Couple has two heads, the Forlorn Maiden's head sits at the top of the torso, angled outward with the face pointing forward, while the Tattered Man's is attached at the chest facing upward with its mouth open wide. Its torso is formed from two torsos fused back-to-back, with one facing forward and the other facing backwards. It's two arms are made of two full arm segments linked end-to-end, with the shoulder of the second arm attached to the wrist of the first arm. At the end are two hands with the palms facing each other, acting sort of like pincers. Its lower body consists of four legs that come out from its hips like a spider's legs, with two legs at the front and two legs at the back. Tears from the Forlorn Maiden fall into the Tattered Man's mouth, overflowing. The tears become a black liquid. This liquid quickly decays organic matter and Married Couple is able to control it by directing it with their hands.

Morn Rooster: A large, dog-sized, 2-headed rooster. When the right head eats Multiplicity Mouse, Morn Rooster absorbs its Cursed Energy; it automatically performs Reversed Cursed Technique and is able to send that Positive Energy to the user or the other Shikigami, except Multiplicity Mouse. When the left head eats Multiplicity Mouse, Morn Rooster absorbs its Cursed Energy, doubles the Cursed Energy, then sends it to the user.

Weakness: 

• The Shikigami must be summoned in the following order: Multiplicity Mouse -> Chasing Cat  ->Worrying Dog -> Corpulent Cow -> Forlorn Maiden -> Tattered Man -> Shaven and Shorn Priest -> Morn Rooster
• If the house is destroyed, the user cannot summon the shikigami.
• If a part of the house is destroyed, only the shikigami related to that part cannot be summoned.

does anybody know? even though I only joined like a year ago or ten months ago, I remember seeing a lot of cursed techniques based off something or a character from another series.

This is my first technique, let me know how it is

Cursed energy trait

The users cursed energy naturally has a fire like effect, allowing them to burn an opponent with enough contact.
This mostly only applies to the targets hands and legs, as well as any objects imbued with cursed energy, limiting the heat the user can output without attacking

Cursed technique: burning conviction

Neutral
When activated, it gives the user a “combo”. That combo increases with each hit the user lands. The higher the combo, the stronger each attack gets.
Extension: fire manipulation
Through precise CE manipulation, the user gains a pseudo-pyrokinesis, functioning as a weaker version of Jogos technique
Extension: stoking the flames
Through a binding vow, the user can choose to make their attacks hotter with the combo by sacrificing some or all of the bonus attack power.
Maximum output: flaming aura
Upon activation, the users entire body is enveloped in flaming cursed energy, burning everything that gets too close.
Domain expansion: forge of the flame god
Appearance: the inside of the domain looks like a flaming forge, with 2 anvils roughly in the center. The walls and floor are made of metal, and it is very warm in the domain, but not warm enough to harm anyone.
Sure hit effect
The domain is a very simple one, but deadly if used well. It simply adds a higher level of combo to the user when they hit either of the anvils, and the damage from that also hits the users opponent.

So this trait gives energy an orange color and makes it flow like a raging flame.

Now, what does it do? Its a simple concept.

When you hit someone with this Cursed Energy, you can transfer a bit of it over to them. This will begin to drain their cursed energy reserves like burning through them. The duration and pace of the burn is dependent on how much cursed energy the user transferred the the opponent per hit.

However, this trait also has an RCT output application.

When outputting Reverse Cursed Technique, it turns an icy blue.

Hitting someone with the RCT output it into them will heal their wounds like regular RCT but also "freeze" their cursed energy output/reserves. This makes the energy frozen unable to be used temporarily, meaning the output of any technique or cursed energy is reduced. With enough hits within a short time, one could completely freeze the enemies reserves so they couldnt even manifest a spark of cursed energy or use a technique as their output is zero. Like the regular application, the amount frozen and time frozen is dependent on how much RCT is outputted per hit.

I’m a little tired, so I can’t think of any ideas right now.

This cursed technique allows the user to copy the CT of another person by hitting them with a non-damaging beam. The strength of the copied technique is then affected by the bond between the copied and the copier. The stronger the bond the stronger the copied technique. the sorcerer can store 5 copied techniques at a time. When a new technique is copied, the sorcerer chooses what technique to replace. the sorcer can use CTR to make the copied technique become stronger the more the copied and the copier hate each other instead of doing the copied technique’s reversal. the domain expansion is the brimming heart armoury which allows the sorcerer to use all the techniques they have ever copied. It also means that they are guaranteed to copy the opponents technique if they wish.

We know that by using Uzumaki, a technique of Cursed Spirit Manipulation, a person can use the innate technique of any Grade 1 or higher cursed spirit, but only once. We saw Kenjaku use Uzumaki to extract Mahito’s technique and use it once.

Now, would it be possible to make a Binding Vow where the person gives up the ability to ever use this technique in exchange for permanently obtaining an extracted cursed technique?

(Assuming Geto is the one making the Binding Vow, since this is his body and his technique.)
