When you strike hard, you knock smaller foes off their feet.
Benefit: If you hit a creature at least one size category smaller than you with a melee attack while using both Power Attack and Vital Strike, the creature that you attacked is also knocked prone. A successful Reflex save negates this effect (DC = 10 + your base attack bonus). You must choose to use this feat before making the attack roll.
Special: This effect stacks with the effect of Giant’s Wallop.
