Entry location: all levels
Have you ever died on bosses numerous times? Here is an easy way to never die but always kill the other bosses. Instead of going straight for the bosses, kill the humans and or goblins first. Then all your units will attack the boss. Stand right next to the boss and just defend. Your army and side heroes will destroy the boss. When the boss has almost no health wait for an opening, get out of block and finish it quick. You'll get just as much experience and you won't die.
