this early in the game; you won;t find bracers until you enter the tomb to the north east. It's still early, so save up for a robe of enfusing for someone. eventually you'll find robes. make sure each of your multi-classed mages has a helmet and a large shield (better for missle deflection). the cleric mage can wear some platemail and still cast clerical spells; then you could take off the armor when you need mage spells?
BTW, if you're jonesing for another Magic Missle spell, you can kill Weenog for one
