You have learned to balance two weapons more precisely in your hands.
Benefit: Any one-handed weapon of your size category or smaller is treated as a light weapon for purposes of determining your penalties for fighting with two weapons. This means, for example, that you could fight with a longsword, a scimitar, or a rapier in each hand and only suffer the penalties for having a light weapon in your off hand. This Greater balance does come at a price in terms of your ability to strike hard; you may not use the Power Attack feat when you are fighting in this fashion.
Normal: You suffer greater penalties when fighting with two weapons and wielding anything other than a light weapon in your off hand.
