Almost all Chocolate Quest mobs carry Healing Potions. When they are low on health, they will retreat and try to attempt to consume a Healing Potion before returning to battle. Boss monsters do not carry healing potions.
When equipping a Dummy you may place a potion in the slot below the right weapon slot. You may place multiple if you wish, however the maximum is 64, as that is the maximum stack size. If a mob has more than one potion, it will drink the potions individually. For example, if a pirate has 3 potions ,it will retreat (if low on health), drink the potion, then return to battle, doing this 3 times.
