Path of the Fractured

Barbarians are defined by their rage, channelling emotion to unleash brief but potent destruction on their enemies. A rare few study esoteric psychological techniques that split their rage off from the rest of their psyche, dividing their identity into two parts: ego and id. When their ego is in control, the Fractured, as these barbarians are known, are capable of a degree of self-control and cunning few other barbarians are. When they allow their id to take control, their countenance turns monstrous and their bodies swell with the power of rage made physically manifest.
