SUNDER: Using your psionic powers, you may sunder the mind of anyone you presently perceive, dealing 1D6 DAMAGE which ignores ARMOR. You may roll additional six-sided dice and add them to the total DAMAGE at will. Opening a psionic channel strains your body (perhaps causing nosebleeds, shaking, or confusion), and you will always take DAMAGE equal to half of what you deal, rounded down.
