Counter Missile
Knowledge that you are not the only one to be able to make a shot can be helpful in defending oneself.
Prerequisite: Dex 13, Combat Reflexes, Precise Shot, base attack bonus +6
Benefit: Once per round, when you would be hit with an attack from a ranged weapon, you can forgo one of your attacks in the next round to prevent that attack with a missile response of your own, using up a piece of ammunition in the process. This literally shoots the incoming missile out of the air. You must be aware of the attack and not flat-footed. Attempting to counter missile does not count as an action. Unusually massive ranged weapons and ranged attacks generated by natural attacks and spell effects can ‘t be prevented by counter missile.
