The monkey wizard staff is a weapon that can be obtained by defeating the Naked monkey wizard in the Cave. It deals 2 melee damage and fires purple magic balls that deal 15 damage relatively quickly. The attack speed is very fast. If you enchant it using a chocolate bar, its attack speed becomes 'incredibly fast' and the speed it fires orbs are increased greatly as well.
Its range is extremely useful in a variety of circumstances. It can be used to grind candies off the Hole (get close enough that they stop regenerating) and its needed for obtaining the double damage X horn.
