@Hazmat Guy no, sorry. There are a lot of elements to it that'd need to be changed and I'm rather unfamiliar with the darkest dungeon that doesn't include TFD so it'd take work I'm not willing to devote over other things.

@Elysian Phoenix is there anyway to apply this mod to the original game, instead of adding in forgotten dungeons?

@Hazmat Guy are you using this as a mod separate from The Forgotten Dungeons? This is a compatibility mod for it not something to use on it's own. Otherwise I'm not sure what could be crashing it. Is there an error message at all?

this mod has ruined my file, keeps crashing when I click on commandant

Man, I'd love to see what you could do with the forsaken or the herald. The undead heroes are my jam and they seem like they'd fit into the forgotten dungeons even better than the vanilla game.
