The force of your blows with a heavy weapon is such that the enemy must pass a Con check (opposed to your hit result) upon a successful hit in order to hold on to his weapon.
When entering an opponent's square, you do not provoke an AOO, nor are you flat-footed while inside. (You still suffer the normal penalties to hit with medium and large weapons)
Recharge 33%, augment; a single melee attack with a light weapon or maneuver becomes a close burst with radius equal to your weapon's reach, striking all enemies within range once.
Costs 5 Stamina, std; you create a path of destruction as you move up to your normal walking speed (not provoking) and hit every creature within 1 square of the path with normal weapon damage +100% (treated as an area effect).
Notes
Power Charge - Increase multiplier of damage by each factor of base move over normal, max against skill rank.
