Extra Arm: Any fighter with a third arm may use it to better handle Unwieldy weapons, or to gain an extra attack in combat. If armed with a ranged weapon with the Unwieldy trait, shooting it becomes a Basic action rather than a Double action. Otherwise, the fighter gains +1 Attack on their profile made as an unarmed attack with the Rending trait. Additionally, any fighter with an Extra Arm may carry a fourth weapon and may attack with three weapons with the Sidearm and/or Melee traits rather than the usual two.
