Awesome Blow

As a standard action, you may choose to subtract 4 from your melee attack roll and deliver an awesome blow . If you hit a corporeal opponent smaller than yourself with an awesome blow , your opponent must make a Reflex save (DC = damage dealt) or be knocked flying 10 feet in a direction of your choice, and fall prone. You can push the opponent only in a straight line, and the opponent can't move closer to you than the square it started in. If an obstacle prevents the completion of the opponent's move, the opponent and the obstacle each take 1d6 points of damage, and the opponent stops in the space adjacent to the obstacle.
