Prerequisites
Dexterity 15, Precise Shot, base attack bonus +6.
Benefit
Your ranged attacks treat cover as if it were one step less. Targets with improved cover only benefit from normal cover (+4 to AC) and targets with normal cover only gain partial cover (+2 to AC). Targets with only partial cover are treated as if they had no cover at all. Your ranged attacks also ignore the miss chance granted to targets by anything less than total concealment. Total cover and total concealment provide their normal benefits against your ranged attacks.
In addition, your precision range increases by 20 feet.
Normal
See the normal rules on the effects of cover and concealment. Without this feat, a character who shoots or throws a ranged weapon at a target involved in a grapple must roll randomly to see which grappling combatant the attack strikes.
