Path of the Tumultuous Mind

Something happened to you. You house an increadible well of psychic power that you are incapable of controlling. Your primitive upbringing did not teach you how best to use these powers, so when you rage they come out. Where this power comes from is up to you and your GM. Maybe you can be cured? But do you want to be?

Psionic Presence 3rd level

 

At 3rd level, while raging all creatures in a 20 ft radius have disadvantage on concentration checks for spells. The radius increases to 30 ft at level 10 

Additionally, 

You can hear telepathic messages sent from within your radius and while raging you can use a bonus action to speak angrily telepathically (as if you were using the spell), everyone in the radius can hear you. 

Psionic Shatter

When you use Reckless Attack, you can choose to supplement any of your attacks that turn for psychic attacks with the range of your Psionic Presence. You are proficient in these attacks and add your constitution modifier to the attack and damage roles. 

The attack deals 1d8 + CON psychic damage and the damage increases to 2d8+CON at level 10 and 3d8+CON at level 14.

Tumultuous Mind

While raging if anything attempts to access your mind with a spell you can add your proficiency bonus to the saving throw. If the spell fails the caster takes damage equal to the spells level Xd6. Example: Scrying would deal 5d6 to the caster on a failure.

Psychic War Cry

As an action you let out a psychic roar that blasts out 30ft in a cone shape. All creatures hit by this must make an intelligence saving throw DC 8 + your constitution modifier + your proficiency bonus. On a failed save they take 3d6 psychic damage and 2d6 force damage and are pushed back 10ft. On a successful save they take half damage. This ends your rage. If a creature is reduced to 0 hit points by this feature, their head explodes. 

Mind of Storms

As an action while raging your psyonic energy blasts into a quarter of your circle in front of you, all creatures in the circle must make an intelligence saving throw or have their movement speed halved for their next turn. If they critically fail they are stunned. 

Head of Screams

Beginning at 14th level, while raging you are immune to psychic damage and being charmed. 

Additionally, Your Tumultuous Mind deals xd8 more damage.
