Your superior expertise with this weapon does not provoke attacks of opportunity from your enemies.
Benefit: You no longer provoke attacks of opportunity when attacking with a whip. You can deal lethal damage with a whip, although you can still deal nonlethal damage when you want. Further, you can deal damage with a whip despite a creature’s armor bonus or natural armor bonus.
