Path of the Iron Body

Barbarians who follow the path of the iron body throw away weapons and armor in favor of training their body to become the only weapon they need. Harnessing the their rage they are able to harden their body to make devastating unarmed attacks, have the grip strength that bests a giants and shrug of blows that would kill a normal man. Barbarians train in many different ways, some by punching iron wood trees for hours on end, others slam their bodies with balls of iron, but this just scratches the surface of how these barbarians harden their bodies. Undergoing training and being able to utilize their rage effectively takes an iron will few can handle. But for those who preserve it is rumored that when entering their rage the barbarians flesh itself turns to iron, in other cases no matter how much damage the barbarian takes there are no visible wounds. When tribes go to war and see a warrior charging into battle with nothing but rage in their eyes they fear the damage that is yet to come.
