You can fight using agility instead of brute strength, even while fighting with two weapons.
Benefit(s): You can gain the benefit of the Fencing Grace, Slashing Grace, or Starry Grace feats while fighting with two weapons. Your penalties from two-weapon fighting increase by 2 on all attack rolls you make when doing so, and you can’t decrease the penalties to less than –2 even if other abilities would reduce the penalties further. Add 1/2 your Dexterity bonus to damage with your off-hand weapon instead of 1/2 your Strength modifier. If you attack without using your off-hand weapon, you can use the aforementioned feats despite your other hand being occupied.
Normal: You gain no benefit from the listed feats if you don’t have a free hand.
