Name: OVERSIZED TWO-WEAPON FIGHTING
You are adept at wielding larger than normal weapons in your off hand.
PreReq: Str 13, Two-Weapon Fighting
Description: You may wield any one handed weapon in your off hand as if it were a light weapon for purposes of two-weapon fighting penalties.
Note that if using the same weapon in each hand is simply too un-aesthetic for you, you may still use this feat to gain the advantages of using two similar weapons. For example if you used a longsword and handaxe, and you took this feat, then any benefit you have for using a longsword (such as Weapon Focus), also benefits the handaxe.
