Werewolf the Apocalypse Rage Across St. Louis
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.
