A ratty, long-haired skin that looks like it came from a cow.
The cow hide is complete to the hooves and face. It looks like it came from some weird species of cow, with somewhat long tawny brown hair and a kind of ratty, mangy look. If you drape the skin over someone, they become a cow until the skin comes off. They still have their mind, but it’s clouded and difficult to think straight. As a cow, you have 1-armor, and can do 1-harm with your hooves.
