You've adapted more of your tendrils and limbs with complex musculature and cellular structures, improving articulation and fine motor skills. Increase your number of arms by two. At any time, one pair of your hands is designated as your active hands. You can change this designation from one pair of hands to another by taking the
Switch Hands action, which is a single action. You can only wield items with your active hands. For more information on playing characters with more than two hands, see
Hands.
