With all due respect, Caretaker is one of the easiest bosses in HOS once you work him out. Like any well designed boss, understand the attack patterns and you will beat him. I beat him on Deathmarch first go, wish there were more like him in the game.I know its not a bug. Just a poorly designed part of the game. I understand people wanting a bit more of a challenge but this doesn't give any but the most hardcore players any chance whatsoever.
