These barbarians cast aside all mental restraint and utilize raw psionic power to crush their enemies both mentally and physically. The barbarians have little control over their power however and are prone to harming both themselves and their allies.

Psionic Fury

Starting at 3rd level when you choose this path, you deal Psychic damage to all creatures with 15ft of you (including yourself) equal to 1d6+INT on a failed save or half that on a successful save (DC = 8+Proficiency+INT), this damage increases to 2d6 at level 6, 3d6 at level 10, and 4d6 at level 14. In addition, you can add your INT modifier to attack rolls while enraged and deal Psychic damage instead of the usual rage damage equal to 1d6 at level 3, 1d8 at level 9, and 1d10 at level 16

Will of Steel

At 6th level, you gain proficiency in INT, WIS, and CHA saving throws while enraged and become immune to the Charmed and Frightened conditions.

Mental Fortitude

At 10th level, you can add your INT modifier to your AC while enraged. In addition, allies now have advantage on saving throws against you Psionic Fury, but you do not. You also can maintain concentration on a spell you’ve cast before raging.

Unshackled Mind

at 14th level, you gain resistance to Psychic damage. In addition, once per rage you can attack a creature with 30ft of you that you can see as a Bonus Action with 4d6 Psychic damage.
