Path of the Devourer

Throught the innate dragon element present in all beings, you have harnessed the power through an internal organ that your body has produced. This organ allows you to have an innate attunement to the dragon elements, to the point of enhancing your body beyond that of normal capabilities. This organ is the source of your power, and such is extremely volatile. The user of this power must be extremely careful as to not unleash too much power, or be killed themselves.

Draconic Adrenaline

At 3rd level, when you rage you gain the ability to make a 15-foot cone breath attack using an attack action that does 1d10 necrotic damage on a failed Dexterity save (DC = 8 + your Constitution modifier + your proficiency bonus). The damage increases to 2d10 at 6th, 3d10 at 10th, and 4d10 at 14th. A target hit by your breath attack that failed the Dexterity saving throw must also make a Constitution saving throw (DC = Constitution modifier + the damage dealt by the breath attack) or be afflicted by dragonblight. While afflicted with dragonblight, the target can't deal acid, cold, fire, lightning, or necrotic damage with its spells and attacks, and it can't impose any of the following conditions on other creatures: blinded, charmed, paralyzed, poisoned, and petrified. This condition is removed when ever the person afflicted by it is healed through magical means.

Devouring Frenzy

Already filled by adrenaline, combat occasionally triggers an intense reaction in your body, the organ pumps you full of power and speed, enhancing your muscles and bones to the point of frenzy. At 6th level, upon getting hit by a melee attack during a rage, roll a d6. If it lands on a 6, enter a frenzy. You gain 1 extra attack (total of 3), another 10 feet of movement, and can roll max damage for 1 single attack during the frenzy. The frenzy lasts for 30 seconds.

Consuming Hunger

The adrenaline rush combined with the energy coming from your internal organ sets off a series of chemical reactions within your brain that override all basic logic functions. Inducing a hunger fueled rush of energy, you strike out at anything you can, no matter who they are to you. In return, your organ fuels a new spread of abilities to sate the hunger. At 10th level, once per rage, you can fill yourself with draconic energy, where you get 1 extra attack (up to 4 with frenzy) and if you land a critical hit you gain 3d6 hp points in healing. However, you must hit the closest creature possible to you with an attack or the hunger ends and you gain a level of exhaustion. It can be ended early if you consume a days worth of rations using an action.

Consumate Wrath

With the organ finally reaching it's full potential, whenever it's triggered it releases a burst of dragon energy that sends shudders down the spines of any who feel it. At 14th level, upon entering a rage all enemy creatures within 60 feet of you must make a Wisdom saving throw (DC = 8 + Constitution modifier + Proficiency bonus) or be frightened for 30 seconds. The extra energy also allows fuels your muscles to the point where your very attacks can pin someone down. You gain the ability to take a bonus action to make a grappling attack that does 2d6 necrotic damage and performs the grapple action. If an enemy is grappled or frightened when your rage ends, they take an additional 2d6 necrotic damage from the expelled energy.
