Glimpses of Hyboria
Rapid Shot (General)
You can have another arrow in the air before the ﬁrst has hit its target.
Prerequisites: Dex 13, Point Blank Shot.
Beneﬁt: You can get one extra attack per round with a ranged weapon. The attack is at your highest base attack bonus but each attack you make in that round (the extra one and the normal ones) takes a –2 penalty. You must use the full attack action to use this feat.
