This game is nice and all you want , but it needs a medium and hard level of difficulty.
I just completed "the root of all evil" (last quest) with only 1 archwizard.
jellinator: clic on the hero panel ; clic on any hero ; find the scroll in the storehouse ; put it in equipment ==> the scroll disappear cuz it is used.
wetfoot13:tactic is "2% less experience to level up" and leadership is "COST 2% less to lvl up"
