I would also like to see some stuff like in the Dark Space module. I already mentioned "oni blood" but something similar to that evil spell list set from RMC IV would be nice. Eh, Foul Changes they were called. Or like the Chaotic Lord. Binding demons to the skin or attaching demonic or undead limbs or body parts to the own body. Or about replacing body parts with something else, diamond eye and stuff like that - although that might be for a different companion. Maybe some effects of using evil magic would also be nice.
