The desert lizard bone is an item on the Odd Old Man's wish list during Rag and Bone Man II. It is dropped by level 42 desert lizards. 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 desert lizard bone before giving it to the Odd Old Man.
- Only during Rag and Bone Man II.
