When you ascend a few time, you can make your armor go up by enough to not be one shot and have enough life that your healer becomes effective, you should ascend as soon as you can the 1st 5-10 times so you can get enough points to make your warrior and healer effective and you can get enough mages that a few corrosions can reduce there armor to zero
um....I just found a bug that probably needs fixed, the mine spell that can be placed can be placed as many time as you want before the game start so you just plant a few hundred and auto win the level....just a heads up to the maker of the game
