A mod that makes it so Undead from Rimworld of Magic spawn with the CorpseChildren trait from the CorpseChildren mod when they are raised from the dead.
So what does this mean for your raised zombies?
Well my friend it means your zombies can steal traits and skills from corpses that have their brains intact or steal their body parts if they are for example missing one of their arms they can rip a new one from a corpse.
so zombies using guns is no longer impossible/horrible. if they eat enough brains(it takes a good load of them) and steal enough skills they can be semi passable at shooting.
NOTE: keep in mind they lose all the traits they gathered when they die just like a normal pawn. this includes being dismissed/losing power from your caster not having any mana. I think its fine the way it is but if you disagree make sure your turn of mana drain in your scenario editor if you want to keep your op zombies around.
Also keep in mind that from what im aware the undead trait is not compatible with other RoM classes so if you get the option to steal a RoM class with a zombie id highly reccomend against it but im not gonna stop you from getting the corpse children RoM compatibilty mod
