-Benefit
When you score a critical hit with a weapon that deals bludgeoning damage, in addition to any other critical hit effect you would apply, you also apply the knockdown critical hit effect. If the attack would already apply a knockdown critical hit effect, you can choose to also move the target 1d4×5 feet directly away from you.
