According to the wording of the spell, the caster removes the skin and eyes from a recently dead creature and then fuses them to their own face, taking on the guise of the deceased. But how different can the subject and caster be? Would an orc caster still have tusks jutting up through an elf's lips? Would an elf gain a bite attack from wearing the face of a tengu? If you've taken a gorgon's eyes and face, would you have a gaze attack?
What is and isn't affected?
Is the limit based on bone structure, or more on what sort of strangeness the GM is ready to allow? Can grandma take off her face and there's the big bad wolf underneath?
