Path of Unyielding Rage

Some barbarians find that the rage within them is far greater than any of their fellow kin. And far more than can be controlled or channeled into tricks or tactics. Special abilities or transformations. For some in the heat of battle unyielding rage takes them and who they were fades away. They are simply the monster others fear.

Berserk

Starting when you choose this path at 3rd level,  when you rage you can go Berzerk. If you do so, for the duration of your rage You can make an extra melee weapon attack as a part of an attack action you take on each of your turns. When your rage ends, you suffer one level of exhaustion. Additionally you may remove one level of exhaustion after a Short rest , or two levels after a long rest. Provided you consume some amount of food and water.

Overshadowed

Beginning at 6th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is ended. Having been overshadowed by your unyielding rage.

Imposing stature

Beginning at 10th level, you can use your action to frighten someone with your menacing presence. When you do so, choose one creature that you can see within 30 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be frightened of you. The creature can repeat this save on subsequent turns, and are made at disadvantage if you are rageing.This effect ends if the creature ends its turn out of line of sight or more than 60 feet away from you.

If the creature succeeds on its saving throw, you can’t use this feature on that creature again for 24 hours.

Violent rebuke

Starting at 14th level, when you take damage from a creature that is within the reach of a melee weapon you are wielding, you can use your reaction to make a melee weapon attack against that creature.
