Eeveelutions Ideas
This'll be where you can leave your ideas for the Eeveelutions yet to be added. Leaving a comment on the page can be long and is easy to lose, so I'd rather they all be here. Thanks!

Leafeon, Glaceon, and Sylveon are as of now, completely undecided on how they function and how to evolve into them. Leave suggestions of how they should play out!

...It's my plan to add all of them, of course. I'm mainly looking for how they'd be implemented and what abilities they'd have.
oh sorry

For Glaceon, you could turn Eevee's tears into a Tech laser with a 40% chance to slow and a 20% chance to stun enemies (fluffed as freezing them), to mimick Ice Beam.

It's a tech laser though. Ice Beam needs to look like a beam. At the very least, I was thinking of a less powerful but slowing Brimstone. I feel like I could do more than that though...but I don't know how I'd go about it.

ooooh! i know! let's wait until repentance comes out, and then use the uranus effect + ice tray from revelations (or copy the script for uranus from antibirth before repentance some how.).

Copy pasting script from a Rebirth mod for an Afterbirth+ mod sounds...not simple. I'd also have to wait roughly 4+ months for Repentance...and even then, I'd probably be playing the game rather than exploring the new modding capabilities. Gotta get that 3,000,100% lol

yeah that makes sense.
It'd be cool to evolve into umbreon by defeating a boss while under curse of darkness, though I guess you'd want it to be something the player has more control over.

Maybe if the player is eevee and its not the first floor you could spawn a 'moon stone' in the devil deal room for umbreon and a 'sun stone' in the angel room for espeon.

Moon Stone and Sun Stone is not the way I want to go. I could just do that for every eeveelution if I wanted to, but that's too boring.
Yeah I thought so, originally I was thinking just taking a devil or angel item on the second floor but then I thought of players who might be waiting on the stone evolutions but still want to take the items

there's a lot of ways the evolutions could be done, the issue is making sure its something the player can deliberately trigger or avoid triggering, if the player had a way to stop evolution it would give a lot more options, maybe eevee starts with an everstone trinket that prevents non-stone evolution? player could drop it when they want to evolve

Then you could have stuff like 'defeat a boss with X devil items to evolve into umbreon' or 'collect X eternal hearts to evolve into espeon'

Really interesting mod, looking forward to future improvements and addition of the remaining eeveelutions. Here's a few ideas regarding the remaining eeveelutions, though keep in mind I have no idea how to mod this game & how difficult these suggestions are to implement.

Ideas for evolution methods:
- Espeon & Umbreon: add "Sun Scarf" (triggers evolution into Espeon) and "Moon Scarf" (triggers evolution into Umbreon). Having either of these evolves Eevee into Espeon/Umbreon upon entering the Womb I floor (or if that's too late, upon entering Depths II) or its equivalent floor. If the player is already on those floors/further floors, advancing to the next floor triggers the evolution.
- Leafeon & Glaceon: add "Mossy Pebble" (triggers evolution into Leafeon) and "Snowy Pebble" (triggers evolution into Glaceon). Having either of these evolves Eevee into Leafeon/Umbreon upon advancing to the next floor.
- Sylveon: add "Fairy Ribbon", which evolves Eevee into Sylveon after advancing two floors or upon reaching Womb I (whichever is earlier).
Note: For these evolution methods, I'd imagine it'll be easier to implement if these evolution items are added as passive items instead of trinkets (since it's possible to have 2 trinkets at the same time in this game). Another idea to make the evolution more controllable by the player is to make an extra active item called "Eevee's Trinket Box" or something like that, which, when used, consumes the active item and spawns item pedestals of all 8 eeveelution items. After one of these items is picked up, the remaining items disappear.

Ideas for mechanics ("movesets") of the other eeveelutions:
- Espeon: gains Spoon Bender and Continuum tear effects [imagine Psyshock], as well as slight speed up and a moderate damage up, with +1 red heart.
- Umbreon: attacks become similar to Maw of the Void dark rings (no need to charge though); charging an attack causes a dark ring to be shot forward (like a Brimstone+Tech X beam) [imagine Dark Pulse with a melee & ranged variation]. Gains +2 red heart, significant tears down (as to compensate for the "melee" Dark Pulse & not make it too spammable - make it increase tear delay like obtaining Triple Shot/Quad Shot).
- Leafeon: melee attack "Leaf Blade" - similar to Forgotten's bone swings - and ranged "Razor Leaf" (think gen 3's Razor Leaf animation) - similar to Forgotten's bone throw but with much wider hitbox. Gains +1 red heart, slight speed up, moderate damage up, and significant range up.
- Glaceon: A slowing (bluish) Brimstone beam that you stated above is a good idea in simulating Ice Beam. Though I was kinda thinking a bit more like the Mei character mod, with icicle-like tears circling Glaceon that can be flung forward (infinite range, until hits a wall/obstacle) when pressing the tear-firing buttons. The tears replenish themselves after a short period of time (respawning up to a certain amount). The circling icicle tears inflict contact damage. Makes Glaceon like an "ammo-based" character that auto-reloads themselves. Gains +1 red heart, tears up, and significant shot speed up. [This might be hella difficult to program though]
- Sylveon: gains Polyphemus tear effect but not as severe of a tear delay increase and way less of a damage up, with a certain percentage chance of triggering Holy Light effect upon hitting enemies with it [imagine Moonblast], as well as +1 red heart.

Any pokemon you like in the future?
That's interesting.... but that doesnt HAVE to go just for REAL pokemon... right?


What im refering to is fakemons... lets say... an eeveelution that havent been made officially yet...
like... how about "Brawleon" where he will be a melee character instead of a ranged character.
Brawleon as in a Fighting type version of eeveelution.

its just an idea.... perhaps to expand this mod in itself a bit further....

I've thought about it from time to time, but I'm unsure. If anything I would maybe add one that's an Isaac-themed evolution, but I'd only get to work on it after all the eeveelutions are implemented.

Maybe you could do an eeveelution for sylveon and umbreon depending on if you went to the chest, or the dark room? Just a suggestion though.

I feel that having it by the time you get to the Chest or Dark Room would take way too long. I'm thinking about it being more related to Angel and Devil Rooms. In fact, I think I have a good idea of how it'll play out. Still somewhat stumped on cool effects for Umbreon and Espeon though.
