Playable Abigail Mod idea

Hi all, I was experimenting with the concept designs for a character Abigail mod.

The pitch is this: after endless loops in the Constant, Wendy has finally figured out how to bring back her sister...at a price. Abigail isn't quite who she once was; but who would be, coming back from the dead?

The idea is for Abigail to be a different type of undead; corporeal and able to speak, but altered by her time as a ghost.

If Wendy is a young, lonely girl who read a lot adult books, and is vaguely suicidal at all times... Abigail was an outgoing, boistrous girl who spent time playing outside, and is vaguely homicidal post-resurrection.

My friend and I came up with her traits based on her behavior as a ghost, and stories of the undead disliking fire.

-Can only eat uncooked foods. (If I want to be nice, this includes jerky.)

-Can eat live mobs in her inventory for [some kind of buff]

-hates fire (receives a sanity penalty when around campfires, torches, fires, and starcaller suns)

-resists cold (no sanity penalty around endothermic firepits, lanterns, mushlights/glowcaps, or mooncaller lights)

- has the monster tag

I was considering giving her the same damage debuff as Wendy, but ultimately I imagine her as a fighter, so I'd leave her damage at least at 1.0x. I'm not sure whether to give her a special item/weapon, or how to really make her an effective fighter over other characters. Maybe she has a baseline resistance from damage, or has some kind of internal speed boost? Maybe she moves faster in the dark or something. I also imagine her skill tree would give her abilities like different undead creatures; a vampire/lifestealing tree is obvious, maybe zombie for damage resistance, and ghost for i-frames?

I'd love feedback! Thanks for reading!
