Rapid Shot [General]
You can use ranged weapons with exceptional speed.
Prerequisites: Dex 13, Point Blank Shot.
Benefit: You can get 1 extra attack per round with a ranged weapon. The attack is at your highest base attack bonus, but each attack you make in that rouns (the extra one and the normal ones) takes a -2 penalty. You must use the full attack action (see page 143) to use this feat.
Special: A fighter may select Rapid Shot as one of his fighter bonus feats (see page 38).
