I like it. Agree, ofc

 

[Da3ggman]

Kris | Susie | Ralsei: Resistance to: Fire Manipulation (In the cooking minigame, fire does nothing to Kris and on board 3 it does very little damage)

Sure, though it should probably just be a minor resistance since these are like the tiniest little fires of all time, and he still gets visibly impacted/hurt by them.

Kris: Extrasensory Perception (Kris can see what other people are doing when they close their eyes and think about them, able to see what Susie, Noelle, and even the Roaring knight are doing, but they interrupt themself in the latter)
Ralsei: Extrasensory Perception (Ralsei, like Kris, is able to see what other people are doing just by closing his eyes and thinking about them)

Looks more like Clairvoyance to me (though that is an extension of Extrasensory Perception, probably better to be more specific on the application).

Ralsei: Transmutation (With PopularBoy, can transform into a plush toy)

This is just transformation, or at the very most, Self-Transmutation; Ralsei's never been shown being able to use it on anything except himself.

Kris: Statistics Amplification (With HoldBreath, Kris can move their SOUL faster)
Kris | Susie | Ralsei: Possibly minor Accelerated Development (In the fight with the Knight the Delta Warriors cause it very low damage but while the battle continues the damage they cause increases more and more)

Surrrrreee? Idk, it could just be explained by them wearing the Knight down slowly, but ig possibly is fine.

Kris: Possibly Attack Reflection (Can reflect attacks with their shield)

This is just a shield....being a shield. Like, Kris just deflects the attack and pushes fake Gerson away, there's no "reflection" being done.

Everything else I didn't mention I agree with, good job!

 

[Kellex]

I've got a few things to say.

Kris: Extrasensory Perception (Kris can see what other people are doing when they close their eyes and think about them, able to see what Susie, Noelle, and even the Roaring knight are doing, but they interrupt themself in the latter)
Ralsei: Extrasensory Perception (Ralsei, like Kris, is able to see what other people are doing just by closing his eyes and thinking about them)

Kris' and Ralsei's extrasensory perception should be applied for Chapter 1 keys since they were able to do this back in chapter 1 and 2, it's just that it didn't have much evidence for it until chapter 3+4.

Ralsei: Flight (Can fly in this scene from chapter 3 and when he was fleeing from the hands of a Titan in chapter 4)

This should be changed to restricted-flight via levitation.

Kris | Susie | Ralsei: Non-Phisical Interaction (Can attack a Guei which is state to be a spirit)

They're also able to interact with water elemental beings like Mizzle and Miss Mizzle.

Kris: Possibly Attack Reflection (Can reflect attacks with their shield)

This is just Kris blocking the attack.

Other than that, this is pretty good.

Immersion is something that I see more as a power of the SOUL/Player or of ERAM itself

Probably not. The fact that Mini Kris can also leave and interact with stuff implies they're simply existing in the same space.

well Kris themselves does it, so even if it was just a SOUL/ERAM thing then Kris themselves should have it aswell. Susie later enters the room and turns the monitor off like normal, so it wasn't just the screen opening up into a real world or anything

And I think that the egg man thing is too ambiguous to add for now

I mean, all Kris does is plug the controller into the console and the SOUL is directly transferred to the mini Kris.
It doesn't seem like this is a natural power of Kris, it could be from the soul but I see it more like this is ERAM's fault or maybe FRIEND since the control is odd and has pink and yellow colors

My point is that this power would not be Kris's and probably less of the SOUL itself, but ERAM's or someone else's
Although I don't know if you mean that if this is the case, when ERAM transfers Kris's soul into the video game, then Kris has immersion too?

I'm honestly not too sure of if the soul in the game is the same as Kris' SOUL. we never see it get transferred from the mini player to Kris and yet we still control Kris normally just fine. we control the mini player from Kris, who still has to fight our control over them to stop the mini player's movement. there's the bit where we control the tiny Kris by itself but I'm honestly not too sure what's going on there lol

The SOUL is always shown where the mini Kris is at the beginning of each minigame but anyway all of that is still a bit vague to add now

Kris: Clairvoyance (Since chapters 1 and 2 Kris can see what other people are doing when they close their eyes and think about them, able to see what Susie, Noelle, and even the Roaring knight are doing, but they interrupt themself in the latter)
Ralsei: Clairvoyance (Since chapter 1 and 2, Ralsei, like Kris, is able to see what other people are doing just by closing his eyes and thinking about them)

I don't think that's what happening in those scenes? In both Chapter 1 and 2, once we leave Susie's POV and come back to Kris and Ralsei they're in the middle of a conversation with him going "That's why, okay Kris?". If the player refuses to see what Susie's doing in her convo with Tenna and when she's getting the notes for that one long piano puzzle, Ralsei gets concerned and really tries to convince Kris to check up on Susie. The implication seems to be that Ralsei wants to distract the Soul away from him and Kris so they can talk in peace about... something, especially since he is the only person besides Spamton to acknowledge the Soul's existence. Especially since Kris does the exact same thing later on to save Susie from the Sound of Justice (closing their eyes to think about Susie, and then somehow tracking her down and saving her, implying that Kris followed the Soul)

that could also just be like... baby Kris' own SOUL probably. but regardless Kris would probably still get immersion as an extension of the SOUL's own abilities

Just because Ralsei and Kris are talking in between doesn't mean they can't see what the SOUL is seeing, plus Kris can see what the knight and Noelle are doing

For Kris specifically that's fair. That said, I still don't agree with Ralsei having it. Nothing proves he can see what we are seeing, since it's quite clear by the "think of the knight" scene that the visions we get come from Kris thinking about these people. The fact he insists so much on Kris doing it if we say no heavily implies he cannot do it himself and relies on Kris doing it first.

After thinking about it I think it could be Possibly Limited Clairvoyance via Player.
Whenever a scene like this happens Ralsei always says "We" or "Our eyes"
In chapter 3 Ralsei doesn't seem to do anything besides "watching" what Susie is doing and in the Weird Route Ralsei seems confused for not being able to see what Noelle and Susie were doing in the room since Kris didn't allow the player to see

Kris: Limited Damage Boost (With the Black Shard, has the ability to do a lot of damage to enemies with the Dark/Star element)

Doing extra damage to Star Element enemies isn't in the item's description, so it can only be inferred from damage numbers, & IIRC, the dubiously canon (Toby said something about stuff not being in Deltarune not being canon.) info about Elemental Pairs from the Spamton Sweepstakes indicating that elements are in pairs; Ergo, anything of 1 element of the pair should also be the other, no?
So the justification might need to explain that (Assuming we accept it.) &/or use Likely.

--Chapter 4 KEY--
Kris | Susie | Ralsei: Non-Phisical Interaction (Can attack a Guei which is state to be a spirit and a Mizzle which are water elementals)

Minor spelling mistake.
There are a couple of issues here.
First off IIRC, Elemental Intangibility is a Power/Ability we list; I'd assume Water is physical. If it doesn't qualify for NPI on the basis that Mizzle is water (& water isn't non-physical.), we may need to list this as like, negation of Elemental Intangibility.

Also, Guei has a problem: Its recruit menu description: "A waxy spirit that generates ghastly flames. Though, not a “real” ghost per se, it has an aversion to whips, water, and the like."
Its own description calls it "waxy" & not a "real" ghost per se, as well as avoiding water. (Whips, too, but that seems to be a Castlevania reference.)
& from Gue's Deltarune Wiki page's trivia section:

• Guei's connections to fire, the mentions of wax in some of the flavor text referring to it, and it drinking wax from a candle at the Cafe indicates that its Light World form is most likely a candle, specifically the memorial candles located in the lobby of the Church.
  • Its flavor text also implies that the candles are for the 3 buried monsters at the Cemetery, sans Gerson Boom:
    • Guei turns its head like a bird.: Crystal
    • Guei wags its tail.: Muttler
    • Guei howls hauntingly.: Shyra

Ergo, Guei is likely a candle, & even in the Dark World, it drinks wax. (Not to mention, being called not a "real" ghost. Though, this may be because it isn't the soul of someone passed on.)

Ralsei: Light Manipulation (With LightUp(SOUL) and Brighten, Ralsei can increase the radius of the light emitted by Kris's SOUL)

Could this be Statistics Amplification in addition to &/or in place of Light Manipulation? The SOUL naturally emits light & is the source.

Susie: Attack Reflection (Can reflect attacks with her axe)

Although we've only seen it for Rude Buster, that is Rude Elemental Damage. We don't know what that is. Energy? Magic?
Still, even if her weapon is the only part making contact to reflect it, this may help support NPI. The only reason I can think of that the weapons & whatnot of the other player characters couldn't do so is that Susie's axe is normally what projects/launches The Rude Buster to begin with.

Delta Warriors: Light Manipulation (With Brighten, Susie and Ralsei can greatly increase the radius of Kris's SOUL light)
Susie: Light Manipulation (With Brighten, Susie and Ralsei can greatly increase the radius of Kris's SOUL light)

Again, could this be Statistic Amplification?

• Sharpshoot: Kris can throw hearts from their fingers at enemies which can do some damage.

Not opposed, but I do wish we knew more clearly what these "hearts" were, but I'm not sure there's evidence for it.

• Rude Buster: Susie fires off a large wave of "Rude Energy" at her opponent, dealing more damage than her normal melee attacks. Capable of launching it 3 times without collecting TP first.

It may be notable that TP seems to be tied to willingness to take an action, but that might be too much to go over in a separate CRT; I mention it for thoroughness's sake. Since such a topic could potentially make this CRT longer & more complicated, I'd suggest -Despite my bringing it up here- that concerns related to it be set aside until the pertinent CRT.

• Embezzeled: Susie can steal items and other stuff from her enemies.

Another typo here, I believe, if you'll forgive my saying so.

I've no other concerns with the CRT. Anything that I did not reply about, I'm pretty sure I support, for what that's worth. Hopefully this is helpful, appreciable &/or not bothersome.

Also, for anyone wondering (Hah.) where I've been for the past month plus in the Deltarune general, I'm still avoiding spoilers on a couple of things. Apologies if anyone minds me mentioning that or this behaviour of mine.

 

[Imaginym]

Probably not. The fact that Mini Kris can also leave and interact with stuff implies they're simply existing in the same space.

An oddity I recall about that scene seems to be that either after beating ERAM/Shadow Mantle Holder (ERAM is the name of the music theme, without confirming if it's the name of the boss.) or upon entering the hallway containing the room that Kris can access, the light from the screen showing The Original Game/Mantle being played seems to disappear; Considering they seem to be in a dark area of The Manhole Dungeon. an area likely to be dark to begin with, it might be plausible this is indicative of the Shadow Mantle Chest's room & room that holds the console for The Original Game/Mantle somehow becoming part of the same space.

Also, FWIW, "Mini Kris"'s internal name is LilKris, & recently, official merchandise appeared naming them as HERO_SWORD, with the other player characters of the games being HERO_AXE & HERO_SCARF. Unsure of their internal names, though.

I mean, all Kris does is plug the controller into the console and the SOUL is directly transferred to the mini Kris.
It doesn't seem like this is a natural power of Kris, it could be from the soul but I see it more like this is ERAM's fault or maybe FRIEND since the control is odd and has pink and yellow colors

My point is that this power would not be Kris's and probably less of the SOUL itself, but ERAM's or someone else's
Although I don't know if you mean that if this is the case, when ERAM transfers Kris's soul into the video game, then Kris has immersion too?

Could it be a power of the controller? Technically, whoever made the controller might have that power, but AFAIK, we haven't seen evidence that the SOUL is booted into
TV Time: The Legend of Tenna, with the other controllers used on Tenna's console(s) for Tenna's modified version of The Original Game/Mantle, AKA TV Time: The Legend of Tenna!.

Notably, Tenna can be found in the Tropic of Love while playing The Original Game/Mantle. He has this dialogue (Sourced from the Deltarune Wiki.):

Tenna (found on Tropic of Love)

• PHEW! FINALLY, SOME PEACE AND QUIET!
• ... I WONDER… IF THEY EVEN LIKE THE GAME...?
• I'M TRYING MY BEST TO MAKE IT FUN, BUT...
• HERE AND THERE, STRANGE THINGS ARE SHOWING THROUGH...
• OH, WHY DID I BASE IT OFF THIS STUPID OLD THING!!
• ... KRIS, OH, KRIS IF YOU COULD JUST SMILE... LAUGH...
• TELL ME I'M DOING SOMETHING RIGHT... PLEASE...
• WHAT THE? I HEAR FOOTSTEPS!
• NO GOOD I NEED TO MAKE MY GETAWAY

"HERE AND THERE, STRANGE THINGS ARE SHOWING THROUGHL... OH, WHY DID I BASE IT OFF THIS STUPID OLD THING!!"
Him calling it "THIS STUPID OLD THING" suggests it may be as old or older than Tenna, & there are odd, uncontrolled or supernatural elements to it; The "strange things" Tenna mentions.

Though, if so, there seems to be a lack of evidence -That I can recall- to indicate that the SOUL is booted into the game without the Odd Controller's use, AFAIK.
(& it does beg the question of what he means by "strange things".)

Also, possibly of note is that the attacks of ERAM/The Shadow Mantle Holder damage Kris as well; When LilKris/HERO_SWORD is hit, we see a hit effect appear on Kris.

FWIW, The Deltarune Wiki says it is also known as:

• shadow_mantle_enemy (game files)
• nightmare (game files)
