Thief and Black Mage are both pretty neat , and Samurai ' s weapon is worthwhile to put on some other Warriors . For multiplayer , both Thief and Black Mage cover Wind and Earth bosses well Thief taking the edge vs . Wind bosses has a huge Earth damage and Black Mage taking the edge vs . Earth bosses bigger Wind damage . For single player , both are pretty squishy and nuke things hard . Thief is pretty solid even for harder events with Drain and stuff , although he doesn ' t really have the elements for next Tower , unfortunately . Then again , neither does Black Mage or Samurai , but if you want a job for the next Tower , Black Mage ' d do best out of the three due to his innate Water resistance next Tower is a Water boss .
