that happened to me too russianspy but my technique realy works i tried it out get lots of paladins and lot of magicians but first get about 4k mana then get ur mana up to 4kmana and summon paladin wiard paladin wizard
i have to restart different computer whaaa and lvl7 and 8 are easy now get the paldin lots of em as a tank then get lots of wizard to attack from afar to kill the protecters and like used in boss battles do hobbits so they dont get to ur wizards when ur tanks die have like 4k mana atleast
