Sleepy Hollow: Your armor is a shining, almost ghastly, shade of white and a bone deep chill passes through you the moment you put it on. Your matching sword gleams in the moonlight, but each swing of your blade is as silent as death itself. It's as if you've become a full-fledged ghost. Once your HP hits 50%, the lower your HP ticks down, the stronger your skills get. The buff begins at 100% when you hit 50% HP, and caps at 500% at 1 HP. Much like a real ghost, you want to drag others close to death so that they can join you in your contempt as well. You lose your sense of reason when HP is low, but recover it when your HP is restored to full.
