Masters of the Wild
You are skilled at utilizing all your hands in combat.
Prerequisite: Dex 15+, access to a form with three or more arms
Benefit: You ignore all penalties for using your off hands. (A creature has one primary hand, and all others are off hands; for example, a four-armed creature has one primary hand and three off hands.)
Normal: Without this feat, a creature suffers a -4 penalty on attack rolls, ability checks, and skill checks made with an off hand.
