From publisher blurb:
Beating an opponent to a bloody pulp is more an art than science, and more than just skill and talent. While discipline is integral to handling the chaos of battle, a true pugilist relies just as much on intuition and the heart of a hero. Advancing with Class:: The Unchained Brawler takes the art of the hand-to-hand combat to the next level, combining elements of both the fighter and the unchained monk so that players can create a completely customizable character that relies on their hands and fortitude to overcome nearly any situation.
And to take the customization factor to the next level, sixteen archetypes are provided for this updated hybrid class as well. While many are tailored after existing Brawler archetypes, new ones are also included such as the Elemental Fist and the Vindicator.
So why face your opponents with just your hands and feet, rely on your very essence to take down your foes the most brutal way possible.
