Benefit: You may make a trip attack using a ranged weapon by targeting the opponent's knees, ankles or other critical points on his legs. This attack is resolved as a standard missile attack with a -4 circumstance penalty on the attack roll, and deals normal damage for the attack, in addition it initiates a trip attack, as if the tripping attacker was a small-sized creature for the purpose of resolving the attack.
