I've been playing a trouble under otari + abomination vaults campaign for about two years now!

I play a level 4 baba yaga witch (familiar master dedication), and my familiar is a button-eyed doll with master's form. Pronouns are they/them, which is especially easy for me because they're never apart. They're the party's utility character- they can fly, pick locks, manipulate distant objects, and their pack has 2 of every mundane/alchemical item in the game. They deal very little damage with the occult spell list but they get into the funniest high jinks.

Insanity rules sound neat! Do you have them written down anywhere?
