You can make an additional attack during a round of combat.
Prerequisite: Base Attack Bonus +6
Effect: Choose a single Exotic Weapon or weapon group with which you are proficient. 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. If you take this Feat with Heavy Weapons, it also applies with Vehicle Weapons.
