You can knock away opponents with a powerful attack.
Prerequisites
Strength 13, base attack bonus +8, Power Attack, Improved Bull Rush, Takedown Rush.
Benefit
When wielding a two-handed melee weapon, you may make a single attack against an opponent as a full-attack action. If this attack is successful, you may immediately make a bull rush attempt against that opponent after resolving the attack. Add half the damage dealt by the attack, rounded down, to your combat maneuver check. You do not need to move with your opponent when making this bull rush.
