Trip (Quality)

When you use a Trip weapon, you get a +2 enhancement bonus on Maneuver Offense checks when attempting the Trip, Drag, or Reposition combat maneuvers. If you are tripped during your own trip attempt, you can drop the weapon to avoid being tripped. In addition, if your trip, drag, or reposition combat maneuver is successful, add your weapon's enhancement bonus +2 to the damage inflicted by the combat maneuver.
