Crab Claw

''It is said that the bodies of all shapestrong folk are a reflection of the lives they lead. Those whose arms are twisted into armored chitinous claws, capable of wrenching the joints and crushing the feeble bones of less endowed foes, are often assumed to be dangerous folk steeped in violence. Whether or not there is any truth to this physiognomy of war is a mystery known only to God, but it is still unwise to trifle with someone who can dismember strangers with a single squeeze of their pincer.''

In addition to the crab claw's natural weapon, the mutated arm is granted 6 natural AV, but cannot wear standard armor. Custom armor tailored to the limb can be purchased from armorers at 5 times the cost of standard armor, but can only be worn on this particular limb.
