Just got to wave 50 before quitting out. The trick is to have a ranger with natures balm and use it on all your characters and summons. The 24 health regen it gives makes the game much easier. For the other characters i went 2 conjurors and a cleric. Make sure cleric has benediction as that is the only way to remove some annoying debuffs. Give only endurance stat increase for your characters except the ranger who gets dexterity. The extra health means they rarely die before they can be healed. Although for next time i think i will try remove a conjuror and put in a warrior with a spear in the back row. That way you could also use inspire and adrenaline and still have two spots in the front for wargolems.
