heres a tip.......
if you having trouble with this game, heres a tip. save your healer and dont let her die. kill as many people as you can before all your units die besides the healer. once all of your units are dead, your healer will gather all your dead unit's spirits and use it to transform into daemon. its sort of like light jak from jak 3, except she uses fire.she has unknown amount of health and and when you hit some one its overtkill, which means instant death. 9999 damage. so there ya go
