This is one of a Magician's weapons. It attacks slightly more quickly than an equivalent level Wand, and does more damage. However, both hands are required to wield it, thus reducing the defense which a Shield could have provided. If you become an Elementor, a second Mage class, you will be required to use a staff as your weapon, like a Psykeeper has to use a wand. You can use the staff to your advantage in many ways.
