I finally got 3/3 in Cheat Death. I must be misunderstanding what it does. I've tested it many times, and each time I get the final blow it says in my battle log:
"Player gains Cheat Death."
"Player dies."
"Player suffers a 10% durability loss."
I pay attention to make sure that i'm looking at an attack that would bring me to 0HP. What's this thing do? From the way I understood it, instead of taking you to 0hp it would bring you back to 10% health. It's not doing that. I'm confused?
