Path of the Fractured Mind

Barbarians are defined by their rage, channeling 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.

• You can roll 1d8 in place of the normal damage of your unarmed strike, and your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
• When you use the attack action with an unarmed strike and are not wielding a shield, you can make one unarmed strike as a bonus action.
• You count as one size larger when determining the creatures you can grapple and those that can grapple you. In addition, your reach with unarmed strikes increases by 5 feet to a maximum of 10 feet.

Level 6: Better Half

At 6th level when you take damage that would reduce you to 0 hit points, you can use your reaction to drop to 1 hit point instead and gain temporary hit points equal to four times your barbarian level. In addition, if you were raging your rage ends, and if you weren't raging you enter a rage (even if you have no remaining uses of your rage). You lose all remaining temporary hit points after 1 minute. Once you use this feature you can't use it again until you finish a long rest.
