Battle Mystery

Upon reaching 20th level, you become an avatar of battle. You can take a full-attack action and move up to your speed as a full-round action (you can move before or after the attacks). Whenever you score a critical hit, you can ignore any DR the target might possess. You gain a +4 insight bonus to your AC for the purpose of confirming critical hits against you. When you are below 0 hit points, you do not die until your negative total is in excess of twice your Constitution score.
