Path of the Elemental Fury

Those that walk the path of the elements have learned to draw upon the fury of the elemental planes in the heat of battle, entering a state of mind where the body and the will of elemental chaos become one.
Unlike other barbarians, these elemental warriors can manifest the extraordinary traits of elements when channeling their rage, whether forming a skin as hard as stone, imbuing their weapons with searing flames, blasting their foes with ferocious winds or adopting movement as fluid as a winding river.

Elemental Rage

When you choose this path at 3rd level, you gain the ability to infuse your rages with elemental power. You select which element you manifest, each granting you an additional feature while raging.

Air

You focus the forces of elemental wind, allowing you to buffet your foes as you strike. As a bonus action when you hit an enemy with a melee weapon attack while raging, that creature must make a Strength saving throw. On a failed save, you can choose to push the creature 5 feet in any direction.

Earth

When you hit a creature with a melee weapon attack while raging, you can harden your bones with elemental earth as a bonus action. Until the beginning of your next turn, you cannot move or be knocked prone, and you reduce all nonmagical bludgeoning, piercing, and slashing damage you take by 1d4. 

Fire

When you start your rage, you ignite searing elemental flame around. Each creature 5 ft around you has to make dexterity saving throw with 10 + your constitution modifier DC. On failure takes 1d6 fire damage.

Water

Your body takes on the fluidity of elemental water, allowing you to move with ease on the battlefield. While raging, whenever you are hit by an attack you can use your reaction to move 10 feet without provoking opportunity attacks.  

Elemental Magic

You can use your action to briefly control elemental forces nearby. You know Absorb Elements.

Elemental Resistance

Starting at 10th level, while raging, you now have resistance to your elemental type of damage. Acid for earth, fire for fire, cold for water and lightning for air.

Elemental Fury

At 14th level you deal additional 1d8 damage of your elemental type of damage, for every weapon attack. Acid for earth, fire for fire, cold for water, lightning for air.
