Clustered Shots

The character takes a moment to carefully aim her shots, causing them all to strike nearly the same spot.
Prerequisites: Point-Blank Shot, Precise Shot, base attack bonus +6.
Benefit: When using a full-attack action (3 acts) with a single ranged weapon against the same opponent, total the damage from all the character's hits before applying that opponent's damage reduction. This total damage also applies to the target's massive damage threshold. All attacks must be with the same ranged weapon at the same target, and thus, this feat cannot be combined with Two-Weapon Fighting.
