This calls to comeback with only 10% health. Does your opponent have to be at full health when you are at 10% to unlock this?
i think you just need to be at 10% health and then defeat your opponent. i havent done it yet but im guessing thats what it involves
I got it by basically taking away their flawless. I don't think it counts if you damage them in the process of it. Not entirely sure, but that's how I got mine.
