Pinpoint Targeting (Feat)
You can target the weak points in your opponent's armor.
Prerequisites: BAB +16, Precise Shot, Improved (Feat), Weapon Focus (Feat), Precise Shot (Feat)
Benefit: As a standard action, using a weapon you chose with your Weapon Focus feat, make a single ranged touch attack against the target's AC. This single attack has the critical threat range increased by 2. This stacks with effects such as Keen and Critical, Improved (Feat). If you critically threaten your target with this attack, your confirmation roll is also resolved as a ranged touch attack.
You do not gain the benefit of this feat if you move before you attack, though you can move afterward, if you wish. This can be used in place of the first attack of a full-attack action, but you may only ever use this ability a maximum once per round (except with an Action Point, though the move restrictions would still apply in that case).
