Return to the Temple of Fiends and warp to the Temple of Fiends Past to begin your final quest.
Thor's Hammer is a nice upgrade for your White Wizard, adding 10 Accuracy and 6 Attack to his pitiful melee offense. You may actually not bother equipping it, though, since it can be used like the Gauntlets to cast Bolt2 at will. Even if your White Wizard has it equipped, it's almost always wiser to use it as an item than to attack with it.
