Awesome Blow

 Needs review
Source: Monster Manual V

Description: You can choose to deliver blows that send its smaller opponents flying like bowling pins.

Prerequisites: Power Attack, Size Large or Larger, Improved Bull Rush, STR 25

As a standard action, the creature can choose to subtract 4 from its melee attack roll and deliver an awesome blow. If the creature hits a corporeal opponent smaller than itself with an awesome blow, its opponent must succeed on a Reflex save (DC equal to damage dealt) or be knocked flying 10 feet in a direction of the attacking creature's choice and fall prone. The attacking creature can only push the opponent in a straight line, and the opponent can't move closer to the attacking creature 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.
