Way of the Iron Body

Monks of the Way of the Iron Body are the true masters of the self, learning techniques that further harness the ki within their own bodies. These monks understand their physical being is both the ultimate shield and the ultimate weapon. An iron body monk stands at the center of combat, unmoving and unyielding, by focusing their ki into their very flesh they are able to harden themselves against physical damage and empower their strikes to pierce any shield.

Outside of the chaos of combat Iron Body monks often surprise those around them with their insight and compassion, mastery of the self also means acceptance of the self and those who follow this monastic tradition understand the internal conflicts of the soul better than most.
