Required For: Improved Two-Weapon Fighting.
Specifics: A character with this feat reduces the penalties suffered when fighting with two weapons. The normal penalty of -6 to the primary hand and -10 to the off-hand becomes -4 for the primary hand and -8 for the off-hand. The Ambidexterity feat further reduces the attack penalty for the second weapon by 4 (to -4/-4). Best results are achieved if the off-hand weapon is light, further reducing the penalty for both the primary and off-hand by 2 (to -2/-2). Rangers receive a form of this feat for free at level 1.
Use: This feat is used automatically during combat.
