Zombie bone

A Zombie bone is a quest item dropped by Zombies during the Rag and Bone Man quest. The bone must be cleaned by adding it to a pot of vinegar and then boiled in the pot-boiler by the Odd Old Man's house north east of Varrock. Once cleaned, the bone can be given to the old man.

These bones will only be dropped by zombies if the quest has been started and not finished.
