I have a team of six all level 42. I put in battle my cleric, my wizard and my berzerker. My cleric is in the back with wizard in the middle and berzerker up front. The cleric does only haste to my wizard and the front guy. When the berzerker falls the knight takes over. If he falls my adventurer takes over. My wizard uses shock and if he falls I have my archer with fire. My wizard, archer and knight have life steal 2. My berzerker and archer have richochett 2. My cleric regen 4 and only attacks when everyone has been hasted or is the last standing. I do use alot of cookies but not that much health potions or revive potions. I may use one or two potions per level maybe sometimes none.
