Stop Hitting Yourself Trophy in BlazBlue: Calamity Trigger

To perform a counter assault you must have 50% heat gauge. While blocking attacks if you time it correctly by pressing 6AB/ + then you performed a counter assault, your character will glow white at that moment you can counter assault. You can do this with a friend or boost it with 2 controllers, use Unlimited Haku-men against Jin and have Jin use SP1 multiple times while you counter assault them all until you unlock the trophy.
