Description: You use your off-hand weapon to defend against melee attacks.

Prerequisites: DEX 13, Base Attack Bonus +3, Weapon Proficiency, Two-Weapon Fighting

When fighting with two weapons and using the full attack option, you can on your action decide to attack normally or to sacrifice all your off-hand attacks for that round in exchange for a +2 dodge bonus to your AC. If you take this option, you also suffer penalties on your attacks as if you were fighting with two weapons. If you are also using a buckler, its AC bonus stacks with the dodge bonus. You can use only bladed or hafted weapons of a size category smaller than your own with this fear.
