d100 Diabolic Mutations

Mutagen Links
Reptilian Mutations
Xor Mutations
Necro Mutations
Lawful Anachronisms to be revised

Im considering other mutation lists including plant, machine (law), elemental, plague, ice, whatever for future.

Devil mutations could be signs of taint, rewards for devilish deeds, sign of a damned soul evolving to devilhood, curse or product of being reincarnated or raised while in hell. Devilish features could be dangerous and unpopular.

This could be a handy table to make new devils with or for unique devils or for rewards for helping devils
