Path of the Demon

No one knows exactly where the fury of a barbarian's rage comes from. Some say it is latent primal energy from the earth itself, or from entities long past. For some tribes, those that settled on the sites of ancient battles soaked in the blood of elder beings, these forces seem to have a will of their own. Barbarians on this path have a chance to lose themselves in their rage, and who knows what dark will wrests control away from this pitied mortal in that moment?

Familiar Weapon

When you choose to enter a rage, a single weapon that you are most familiar or attuned with will begin to manifest demonic qualities. A fiendblade may sprout horns or spikes, dripping blood, or an abyssal blade may darken and emit vapor. You can summon this weapon using a bonus action, and it will appear in either fire or shadow.

Awoken Mind

You struggle to maintain control of your will and consciousness while you rage. You must make a DC 5 Wisdom check, and if you succeed you remain lucid and can attack targets you choose. If you fail, you slip into unconsciousness as a Chaotic Evil entity takes control of your body. Your stats remain the same, but your will is no longer your own. You will attack creatures closest to you, be they friend or foe, and continue to do so until your rage ends. At the start of your turn if you are not in control of your body, you must re-roll the Wisdom check, to attempt to regain control.

Demonic Influence

Demonic blood has tainted the land you came from, infecting every bite of food, every drink of water, and every breeze that blew through the region. At 3rd level, when you choose this path, your rage gains aspects the entities that stained the land with their deaths. You must choose how you were influenced at the 3rd, 6th, and 14th Barbarian level.

Fiendish Fury. Your rage is decidedly manic and frenzied, and you attack with the fury of a fiend or devil. Starting at 3rd level, when you rage you may choose to use your bonus action to make a melee attack. Doing so will automatically cause you to fail your Awoken Mind check, and you no longer can distinguish between friend, foe, innocent, or guilty. Additionally, to use this feature, you must use the Reckless Attacks feature, which will grant advantage on attacks against you until your next turn.

Abyssal Hunger. Your rage is fueled by a mysterious dark presence that seeks to devour life, and see it pulled into the void between the stars. While raging, whenever a creature within 5ft of you dies, that creature's life force is drained, infusing you with a fleeting mockery of health. You gain temporary hit points equal to your barbarian level times your proficiency bonus, or the creature's maximum hit points, whichever is lower. This feature replaces the barbarian's resistance to bludgeoning, piercing, and slashing damage.

Devil's Due

Fiendish Fury. You are furious and fast - nothing will escape. At 6th level your movement speed is increased by 10ft while raging.

Abyssal Hunger. The demon's hunger heightens your senses until you can smell the blood of the living. At 6th level, while raging, you can use a perception check to detect living creatures within 60ft. Has no effect on constructs or undead.

Inside Voice

The entity influencing you exerts more control than an outside magical influence. At 10th level you can't be charmed or frightened.

Master of the Dark

Fiendish Fury. At 14th level, you can use your bonus action to cause magical chains to spring forth from your weapon and attempt to attach to an enemy creature of your choice. The creature must succeed on an athletics or acrobatic check. If it fails, and is an equal size class or smaller, you will pull it to a space of your choosing within 5ft of you. If it is of a larger size than you, you will be pulled to it. If it succeeds on its check, then the feature has no effect. You cannot use this feature through solid objects. You must finish a short or long rest to use this feature again.

Abyssal Hunger. At 14th level, the void has become a part of you, spreading darkness and fear before you while you rage. You gain the ability Devil's Sight. You may also choose to cast either the spell Darkness as a 3rd level spell or the spell Fear as a 3rd level spell onto your weapon. Enemies who are within 15ft of your weapon have disadvantage on ability checks and attack rolls as they are either blinded or frightened, depending on which spell you cast. You do not need material components or to maintain concentration if this feature is used to cast the spell. It cannot be cast during rage, but can be maintained while raging. You must finish a short or long rest to reuse this feature.
