You can focus will into a shot, making it more accurate.

Prerequisite: Point Blank Shot, Precise Shot, Charisma 12 or higher

Benefit: As a full round action that invokes attacks of opportunity, you may add your charisma modifier to the attack roll of a single ranged attack. For every four points of Charisma over 10 you have, the threat range also increases by 1. This stacks with keen weapons or the Improved Critical feat, but it is not multiplied by them.

Special: Fighters may take this feat as one of their bonus feats.
