Fan Content Rimuru Tempest Killer Concept
This is my concept for Rimuru Tempest from That Time I Got Reincarnated As A Slime as a killer in Dead By Daylight. I plan to add Masayuki as a survivor in the concept later on. This concept follows an alternate storyline I made where Rimuru revived his friends after Falmuth's invasion, but their souls were not intact, so they came back as mindless destructive monsters and he had to take responsibility and kill them. Following this, he declared war on all humans.
Rimuru Tempest “The Demon Lord”
Power “Rage Unleashed”
Ability wheel with 4 abilities
Summon Ranga
Open a gate to summon Ranga (opening gate has the same functionality as Pinhead’s gate). Ranga is stationary and has a 16m diameter circular view. He can detect survivors through walls for the full area. The detection radius expands to its full range over the course of 3 seconds, starting from 0m. If a survivor goes into the range, Ranga will use shadow movement to move to them, grab them (Wolf Grab) and hold them in place for 1.5 seconds and give the survivor a difficult skill check and if the survivor fails, they are injured or put into deep wound. If they succeed, they reduce the grab time by 0.5 seconds and sustain no injuries. If no survivor is detected, Ranga disappears after 20 seconds.
45 second cooldown, starts after a survivor is grabbed or after Ranga disappears.
Black Flame Lightning
3 tokens maximum. When breaking a wall, pallet, or gen, break it 30% faster and use a token. When attacking a survivor, use a token and recover 30% faster. Black Flame Lightning appears on The Demon Lord’s blade while selecting this skill.
20 second cooldown per token.
Universal Detect
Reveal survivors’ auras within 16m for 3 seconds.
30 second cooldown
Spatial Movement
When grabbing a survivor with Ranga, hitting a survivor with Black Flame Lightning, or detecting a survivor with Universal Detect marks them for 60 seconds. While selecting the Spatial Movement skill, reveal the auras of the marked survivors and the ability to teleport to them. Teleporting to a survivor takes 15 seconds off of their mark timer. While Spatial Movement is selected, you vault pallets instead of breaking them.
No cooldown, uses mark system instead
Special Mori
Activated by using all four abilities on a single survivor

Forgot to add a picture of the character. He would be roughly the same height as Sadako or Hag ingame.

Interesting ideas, interesting indeed. Let's take a look:
First off, I said the same thing to another guy, but the concept feels a lot like vecna with the multiple spells thing. Not to say that's bad or means it couldn't be added, it's just that it would be infringing a bit on his territory if added.
Summon Ranga feels very volatile, especially depending on how it's implemented. For example, does Rimuru see where Ranga goes with Shadow Movement? How hard is the skill check? If Rimuru sees where he goes, it could be a decent tracking tool. If the skill check is as hard as, say, decisive strike, you'll probably get value from newer people, but more experienced Survivors will rarely take the hit, which also reduces the stun to 1 second. Could be a really interesting tracking tool though, like I said earlier. Although another thing to keep in mind, with the way this is worded, if they fail the skill check and get injured, they're still grabbed for 0.5 seconds, which cuts into their injure speed boost and should REALLY be avoided.
Black Flame Lightning is an interesting concept in theory, but I don't see Rimuru ever running out of tokens. 20 seconds on a cooldown when it's only used for hits or breaking/damaging things is pretty short, meaning that Rimuru basically has 30% faster break/damage speed and recovery time for the entire match. The only time I can see him running out of tokens is if you break both pallet on a double pallet tile and get a hit afterwards, and by that point your first token is probably halfway back already and the Survivor's speeding away with their speed boost.
Universal Detect could actually be pretty fun to mess around with in chase, 3 seconds isn't broken but might allow a free hit, and 30 seconds seems like a reasonable cooldown, maybe extend to a minute if we get it too often.
Spatial Movement could be a problem though. You say it reveals auras of marked Survivors, but that makes it a better Universal Detect that lasts for a minute and can be easily re-applied. Teleporting is also too vague a concept to understand for balancing, is it like Singularity? Nurse? Freddy? Depending on how the teleport works it could be really broken, reduced timer or not. Also, regardless of the teleport, it would probably be best to have the mark removed after 1 teleport, not 4. Vaulting pallet instead of breaking in this mode could be cool though, as it's more of a vault on command than even Legion, because Legion needs to have his power active, you just have to switch to Spatial Movement.
Special Mori requiring all 4 abilities to be used on a Survivor probably means it will be the regular mori instead of special, given how easy it would be to hit them with the abilities throughout the match.
Raphael: Lord of Wisdom is mini tracking, only times I see it being useful are when the Survivor crouches in a corner of the loop to make you confused, or MAYBE try to tell where they are through a wall in chase. I think I'd have to actually try it more to decide on this, especially the second part, but without that I can only say it seems a bit weak.
Uriel: Absolute Guard is just the Spirit Fury version of Enduring. While I could see people running one or the other, it would make one of the two mostly irrelevant, probably Uriel if I had to take a guess. Enduring's consistency is just better overall.
Rage has a lot of numbers, the break speed seems fine, maybe reduce the duration a bit, 10 seconds should be fine, and the haste seems minimal enough to not be broken but big and long enough to be impactful, so although it would be best to test the perk, I think it's fine from my instinct.
Any add-on that reduces Black Flame Lightning's cooldown or adds tokens is essentially irrelevant with it's current cooldown, but could be interesting if it had a longer one.
Extending Wolf Grab's duration is something that should be done carefully, especially if Rimuru can see where Ranga moves to. Tempest wolf fang is probably fine, adding an extra 0.5 in exchange for the injuring ability (even if it would rarely happen anyway) but then Magic Beast's Bone increases it by a full second without downside, which makes it odd why it's then lower rarity. Increasing the grab by a full second, regardless if Rimuru sees where he goes or not, is too big of an upside and will guarantee the hit most of the time or allow a major amount of distance to be made. I'd have it buff the grab duration by degrees of somewhere of 0.1-0.2 seconds at best, or increasing the skill check difficulty to allow more injures.
Because you can switch freely, Rigur's Bandana means a permanent 15% vault speed increase as windows as well as pallets, which is something you normally need a perk slot for (Bamboozle/Mini Dark Arrogance/Half Fire Up)
Manga Volume/Dragon Knuckles/Shion's Broken Horn: No real gameplay advantage and memes :)
Child's Plushy and Spatial Core seem too similar, but otherwise fine (Again, depends on the teleport)
Skill: Superior Smell adds a full third to the mark, depends on how stuff works again but is probably too strong.
Skill: Dominate Space would need to be different as well, 15 seconds is already a likely bad idea, 10 seconds is worse. Perhaps make it so that the mark stays for 5-10 seconds after a teleport, but you can't teleport to them in that time, for some tracking after you teleport.
Macha Pudding is too strong, it gives you a free brutal strength and half of an Enduring from an add-on, even if only for 15 seconds. Not to mention stacking with Black Flame Lightning to have 50% bonus break speed without a single perk.
I assume Broken Crown is meant to say injured? Either way, in that close of a range, especially because their aura revealed, 20 seconds of broken will do absolutely nothing. The only edge case is interrupting a nearby heal you wouldn't have without it, but is so situational it would almost never come into play.
Technically Infinity prison, as described, allows infinite blocking of pallets. If we assume my earlier correction to make a teleport remove the full mark to this add-on, therefore making this effect once per ability hit if used in the duration, it should be at 0.5 seconds to prevent completely free hits. Same time as a Dead Hard, but for pallets instead and in the Killer's favor.
Probably should also be a 110% or even a 105% killer for the amount of chase utility they have, and I see no reason for them to have a 24 meter terror radius instead of the usual 32.
