The werewolf bone is an item on the Odd Old Man's wish list during Rag and Bone Man II. It is only dropped by werewolves[1]. After the quest is completed you can no longer obtain this as a drop. The bone must be put into a pot of vinegar and boiled to create a polished werewolf bone before giving it to the Odd Old Man.
