At the end of this certain area, you have to fight a boss for a piece of a key.
He is death and has pretty high health.
He uses ice stun charm on you indicating either ward dance or charm dance.
It seemed when I used a blade it took the charm off and I was protected from his cheating attack.
My minions on the other hand weren't so lucky. They were healing away..oh yea thats another thing, he uses death bubble so its hard to heal. If you dont use a blade or ward when he places a mark on you, then he will use frakenstein on you. He does his "wardance" about every 2-3 turns.
