Two-Weapon Fighting, Greater (Feat)
You are incredibly skilled at fighting with two weapons at the same time.
Prerequisites: Level 16, Two-Weapon Fighting, Improved (Feat), Two-Weapon Fighting (Feat)
Unlocks: Two-Weapon Fighting, Perfect (Feat)
Benefit: By taking this feat you get a third attack with your off-hand weapon along with the third attack in your full attack action, at the same penalty to your BAB as your main-hand third attack, or, at a -10 to-hit compared to your primary attack if your class does not normally possess a third main-hand attack.
The extra attacks with the off-hand weapon can be made against the same target you attack with your main hand, or a different target within reach.
Because the extra attacks with your off-hand weapon are performed using the first, second, and third attack actions of your full attack, anything that causes you to lose or use up any of these attack actions would also prevent you from gaining the respective extra attack with your off-hand. For example, trading away your third attack to make a five foot step would disallow both the third attack with your main hand and your third attack with your off hand.
Special: If you use this feat to fight with a light weapon in your off hand, the penalty to-hit with both hands is reduced. See chart below for your exact circumstances.
Normal: Without this feat, you can only get a single extra attack with an off-hand weapon.
