Activated; cooldown 50.
You make an attack with a cudgel at an adjacent opponent at +1 penetration. If you hit, you slam your opponent backwards up to 3 spaces, pushing other creatures and breaking through walls if their AVs are less than 5 times your strength modifier. Opponents who get pushed are stunned for 1 round plus an additional round for each space pushed. Opponents who are pushed through or against walls take extra weapon damage for each wall. Colossal opponents don't get pushed but are still stunned for 1 round.
You can also use this power to destroy a wall or door if its AV is less than 5 times your strength modifier.
