Double Attack

Double Attack
You can make an additional attack during a round of combat.
Prerequsites: Base Attack Bonus +6, proficient with chosen weapon or weapon group
Benefit: Choose a single exotic weapon or one of the following weapon groups: advanced melee weapons, heavy weapons, pistols, rifles, simple weapons. When you use the full attack action, you may make one additional attack when wielding such a weapon. However, you take a -5 penalty on all attack rolls until your next turn because you’re trading precision for speed.
Normal: Making a single attack is a standard action.
Special: You may select this feat multiple times. Each time you select this feat, it applies to a different exotic weapon or weapon group.
