Path of the Mind Breaker

Widely held beliefs of barbarians are those of savages, using their rage to simply kill. However, there are those who are touched in some way through aberrations or something else from the Far Realm. Their mind and intellect now fuel their rage and manifest into psionic power.

Barbarians of this path forge their anger with intellect, both to hamper the enemy and coordinate with their allies. These powerful combatants usually have some sort of physical manifestation of their psionic power. Some may have a purplish tint to their skin, no pupils in their eyes, or constantly secreting mucus. 

Psionic Edge

Starting at 3rd level, your weapons echo with your psychic abilities which whisper eldritch secrets in your mind. Whenever you rage, you add additional damage equal to your Intelligence modifier.
