Apeskin

Gnosis 6
This somewhat gruesome fetish is nonetheless highly useful for metis and lupus Garou who need to hide their true nature. When activated, the fetish — which takes the form of a scrap of ape or human skin tattooed with a glyph — makes the werewolf suffer no special damage from silver in Homid form, and also renders the Garou unable to regenerate in that form — just as though they were born homid. One activation lasts for a full day. To create an apeskin, a homid ancestor-spirit must be bound into the skin.
