You are able to make ranged attacks while Charging.
Prerequisite: Base Attack Bonus +4.
Effect: When you Charge, you may make a ranged attack instead of a melee attack at the end of your movement. Unlike a normal Charge, your momentum does not help you overcome your target, so you gain no bonus on your attack roll. As with a normal Charge, you still take a -2 penalty to your Reflex Defense.
Normal: You can make a single melee attack with a +2 bonus on your attack roll at the end of a Charge.
