|benefit=While accepting at least a -2 penalty to the Power Attack feat, you may force any foe you hit to make a Fortitude save (DC 10 + your [[Strength]] modifier + 1/2 your BAB + penalty to attack you take from Power Attack) or move in the opposite direction from you if that square is unoccupied, and you may move into a square that foe was occupying. Neither your nor your opponent's movement provokes an attack of opportunity.
