Two Elements down, one to go. Oddly enough, the Lightning floors are the one set of elemental floors without damage squares. The first floor consists of pathways criss-crossing a chasm. The north path leads to a Potion, while the south path leads across to the east side. Follow that path back around to the southwest, checking out the northern T-shaped path for the Wizard's Staff. This interesting weapon has a powerful ability, but one that can backfire. It is also quite powerful in combat, if you have a staff user.
