Parry (Combat)

 

Prerequisites: Base attack bonus +1, Combat Expertise

Benefit: Whenever you are attacked by a melee weapon attack while you are fighting defensively or taking a total defense action, you may choose to make a combat maneuver check as an immediate action, which, if successful, negates the attack entirely. If you fail the check, the attack against you automatically hits, though the target still rolls an attack roll to determine if the hit is a critical hit.
