You have learned to take your time with the most important ranged attacks to make sure that you hit your intended target.
Benefit: You may spend a full-round action, during which you do nothing but aim at a target with a ranged weapon, and receive a +2 bonus to your attack roll on that target the next round with the ranged weapon. (You may aim for up to three consecutive rounds, or your Wisdom bonus in rounds, whichever is less, gaining a maximum of +6 to the attack roll on the fourth round.)
Firing after aiming requires use of the full attack action, in which you gain all benefits at your highest attack bonus, but only make a single attack. If you are threatened or attacked while aiming, all modifiers from this feat are lost until you are able to start over.
