Manyshot

Combat

You can fire multiple arrows at a single target.

Prerequisite: Dex 17, Point-Blank Shot, Rapid Shot, base attack bonus +6.

Benefit: When making a full-attack action with a bow, your first attack fires two arrows. If the attack hits, both arrows hit. Apply precision-based damage (such as sneak attack) and critical hit damage only once for this attack. Damage bonuses from using a composite bow with a high Strength bonus apply to each arrow, as do other damage bonuses, such as a ranger’s favored enemy bonus. Damage reduction and resistances apply separately to each arrow.
