Mighty Throw p. 73
You use superior leverage and your Setting Sun training to send an opponent tumbling to the ground.
As part of this maneuver, you must succeed on a melee touch attack against your foe. Resolve the throw as a trip attempt (PH 158), but you do not provoke attacks of opportunity, and your opponent cannot try to trip you if you lose the opposed check. You can use your Dexterity or Strength modifier, whichever is higher. You gain a +4 bonus on the ability check.
If you succeed in tripping your foe, you throw it up to 10 feet away from you. The target falls prone in the destination space. You choose where it lands. You must place the target in an empty space. If you lack the distance to throw your target into a clear space, it falls prone in its current space.
An enemy you throw with this maneuver does not provoke attacks of opportunity for passing through enemies' threatened areas as part of the throw, and you can throw an enemy through occupied squares. The trip attempt required by this maneuver is not restricted by the size categories of you or the target.
