Joe Dever's Lone Wolf Console Edition

This one seems to be glitched in a positive way. I was in a fight against 2 Giaks, once I killed one of them, a third joined that had a shield. Although I was trying for this trophy, I was worried I would get killed soon, so finished off the final enemy before I reached 150 health. At the end of the fight, my health was at 363/2250, but the trophy still unlocked.

If you have trouble getting this to unlock, then wait until you find a weak enemy such as a Giak, take his health down until you have almost killed him and then let him hit you until close to death. Take your final strike and it should then unlock.

I got this in my third fight of the game, so it doesn't seem like one you have to go out of your way for.
