Path of the Warbound

Upon reaching 3rd level, you create a pact with one of the various gods of war. Instead of becoming a warlock, you instead gain an avatar of war which forms around you while raging. 

Level 3: Avatar of War

Upon reaching 3rd Level, while within rage, when you kill an opponent you gain an crimson red avatar of which forms around you increasing your height by an additional foot. While in this form, you gain temporary hit points equal to half of current hit points. For any opponent you’ve killed while in this state, your strikes deal an additional 1d4 force damage. For every turn you are in this avatar state, you consume a rage slot. Once all rage slots are used, your rage is forcefully ended and you gain two levels of exhaustion.

Level 6: Bloodshed Skills

6th Level: Once you reach this level, you have the choice between three Warbond skills which can only be used as an action in the avatar of war rage state. These Bloodshed skills use your strength modifier and consume one rage slot. You gain one at 6th level and an additional skill at 14th level. 

Eldritch Armor

As an action, your avatar of war dawns a more darker colored armor and gains resistance to magic damage along with additional AC equal to your strength score.

Eldritch Breath

As an action, the head of your avatar of rage dawns (an appearance of your choice) and launches a 100-foot-long, 5-foot-wide beam of eldritch energy in a direction that you choose. Each creature in the Line takes 8d6 force damage and no longer gains the additional AC benefits of shields and or armor until the end of combat.

Eldritch Disk

You create a spinning disk of eldritch energy the size of the weapon in your hands. You cannot use weapons you haven’t equipped. You launch the disk within a direction you chose within 30ft. The disk deals normal damage equal to the damage of the weapon and the additional force damage for each kill. The disk lingers for an additional turn but the damage is reduced by half. More than one disk can be thrown at one time but consume an additional rage slot.

Level 10: Warbound Avatar

Once you reach 10th level, while within rage as a bonus action you can make your avatar stronger at the cost of consuming two Barbarian column slots and become the Warbound Avatar. Instead of gaining resistance to slashing, piercing, and bludgeoning, you become immune instead and your current temporary hit points are doubled. Once your rage is forcefully ended while in this state, you gain four levels of exhaustion instead of two. 

Level 14: Controlled Rage

Once you reach 14th level, your avatar takes one turn longer to consume a rage slot and Bloodshed skills no longer require an additional rage slot to be consumed before usage. While the Warbound avatar state still requires two to be consumed per turn.
