I'm playing an Alchemist that is taking the Vestigial Arm (Ex) Discovery:
Benefit: The alchemist gains a new arm (left or right) on his torso. The arm is fully under his control and cannot be concealed except with magic or bulky clothing. The arm does not give the alchemist any extra attacks or actions per round, though the arm can wield a weapon and make attacks as part of the alchemist’s attack routine (using two-weapon fighting). The arm can manipulate or hold items as well as the alchemist’s original arms (for example, allowing the alchemist to use one hand to wield a weapon, another hand to hold a potion, and the third hand to throw a bomb). The arm has its own “hand” and “ring” magic item slots (though the alchemist can still only wear two rings and two hand magic items at a time).
Special: An alchemist may take this discovery up to two times.
My question is: would the arms grant a bonus to grapple? The rules for grapple state "Humanoid creatures without two free hands attempting to grapple a foe take a –4 penalty on the combat maneuver roll.". One obvious benefit of the arms means you can leave two hands free to grapple without penalty and use a light weapon in an extra hand. But if you have all four arms free logically I would think you'd be better at grappling. There's no rules I've found dealing with extra limbs, at least not in regards to grapple. If not having two arms free is -4, would it be reasonable to say two extra arms grant a +4?
