Swift Repose (3.5e Martial Artist Maneuver)
From D&D Wiki
To beat an opponent means strength. To beat an opponent without hurting him means true skill.
Level: Soft 1
Description: When you are the target of an attack, you may make an opposed Concentration check. If you win, you harmlessly veer off the opponent's strike with a soft palm thrust and may choose to immediately make a trip attempt with a +2 circumstance bonus to opposed checks.
