Bones to Peaches must be unlocked as a reward from the Mage Training Arena. Bones to Peaches can be made into tablets. One cast changes all bones in the player's inventory to peaches. Peaches can only be obtained by this method.
Peaches are untradeable, and cannot be noted. They are most often created and used on long training trips far from a bank, when killing monsters that have bones as a 100% drop.
