Precision Leadership

Leadership, Point Blank Shot

When making a ranged attack, each of your followers gains a +1 bonus on the attack roll for every 5 followers attacking at the same time. All followers must be near you, within a radius equal to 10 feet × your Charisma bonus, and must attack with the same kind of weapon. The followers must attack the same target, which must be within 100 feet of you.

You and all the other followers that are attacking fire a ranged attack at the same target, then the damage from all the hits is added together before any damage reduction is applied.

By training your followers to coordinate their fire, you have turned individual soldiers into a single deadly ranged weapon.
