Path of the Plane Breaker

These barbarians were once normal people thrust into unethical magical experimentation, forced to endure lengthy exposure to the raw, ever-churning chaos of the Outer Planes, they came back with a little bit of that power inside themselves, and slowly learnt to harness it to their own ends to become incredible beacons of might and terror, cleaving through enemies and tearing apart reality with the pure power of their own rage.

  

Planar Juggernaut

At 3rd level you gain resistance to both psychic and force damage while raging.

Astral Cleave

Also, at 3rd level, while you’re raging you gain a new attack ability. When holding a melee weapon, you can let loose a blast of astral energy. The blast has a range of 15ft, and you are considered proficient in it as long as you focus it through a weapon you are proficient in. The blast deals force damage equal to the weapon damage die + your Strength modifier. Any Barbarian feature that affects your melee attacks can also affect this feature. When you gain the Extra Attack feature, you can use this as either of your attacks.

Mystic Fortitude

At 6th level you can use your fury to cloud your mind from external influence. You and can add your Constitution modifier to Wisdom and Charisma saving throws and cannot have your mind read while raging.

Disruptive Step

At 10th level you can use your reaction when a creature within 15ft of you hits an ally to teleport up to them and make a melee attack. The damage of this attack is considered to be all force damage. You can use this feature a number of times equal to your Constitution modifier and regain all uses on a long rest.

Rage Throughout Realms

At 14th level, while raging you draw on ethereal energies to move through physical objects. You can move up to 5ft through an object’s or creature’s space and take 1d4 force damage for every turn you end inside an object or creature. In addition, any force damage you deal while raging deals an additional weapon die worth of damage.
