Bones to Peaches is a spell that turns all bones in your inventory in peaches. The spell will work on any bone up to and including Big bones, while ignoring any other bones. It will not work on any bone that gives more experience than Big bones or any other type of remains, such as ashes. Peaches are a basic food that heals 8 hitpoints, making this a viable method of acquiring food when training on monsters that drop bones and don't require a more potent source of healing.
