Bone in vinegar (Troll bone)

Bone in vinegar is an item used during the Rag and Bone Man wish list. It is made by using the troll bone with a pot of vinegar. The bone in vinegar should be brought along with logs to the pot boiler near the Odd Old Man. The pot boiler should be lit with the logs, which will result in a polished troll bone after 12 seconds.

Emptying the pot will return an empty pot, but destroy the troll bone.
