Two-Weapon Fighting, Improved (Feat)
You are skilled at fighting with two weapons.
Prerequisites: Level 6, Two-Weapon Fighting (Feat)
Unlocks: Two-Weapon Fighting, Greater (Feat), Two-Weapon Fighting, Perfect (Feat)
Benefit: In addition to the standard extra attack you get with an off-hand weapon as part of the first attack of your full attack action, you get a second attack with your off-hand weapon with your second attack in your full attack action, at the same penalty to your BAB as your main-hand second 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 and second attack actions of your full attack, anything that causes you to lose or use up either of these attack actions would also prevent you from gaining the respective extra 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.
Normal: Without this feat, you can only get a single extra attack with an off-hand weapon, which can only be used during the first attack of your full attack action.
