Pugilist

The path of the pugilist is one of incessant training aimed at mastering the traditional techniques of hand-to-hand combat. Though pugilists command formidable power when unarmed, they are wont to use metal, leather, and bone weaponry to maximize their destructive potential. Their preference for fighting at close quarters makes negotiating distances an absolute necessity. Many among them accomplish this by avoiding burdensome armor, allowing for maximum mobility while they move in for the kill.
