Psionic Fist [Psionic]
Prerequisite: Str 13+.
Benefit: The characters unarmed strikes deal +1d4 points of bludgeoning damage when he or she pays the cost of 1 power point. The character must decide whether or not to pay the cost prior to making the melee attack. The characters hand or foot remains charged for a maximum number of rounds equal to the characters Strength modifier +1, or until the character makes his or her next attack, whichever occurs first. If the attack misses, the power point expenditure is wasted.
