Abrasive Skin
From Activating Evolution
Abrasive Skin is the presence of an outer layer of skin capable of scraping or scratching subjects who come into contact with it. This skin may be rough and abrasive for any number of purposes. It could be skin likened unto rock or stone, or covered in spikes like a porcupine, but never a mixture. One with this ability can, in many cases, suppress and activate it at will.
