Path of the Abyss

All barbarians harbor a fury within. Their rage grants them superior strength, durability, and speed. Barbarians who follow the Path of the Abyss either willingly pursue this path through various forbidden and vile rites, pacts with Demon lords or stem from a bloodline tainted by demon blood. Some even seek to use demonic powers to hunt the very demons being the source of this power. Regardless of how they got to where they are, if their desires are vengeance...a lust for chaos and carnage, or just a daily struggle against their inner demon, they are a powerful conduit to the abyss. Feared by many, wanted by others, they are often driven to wander and gladly accepts whatever challenge may further increase their power or give them the sweet taste of defeat.

Demonic Powers

Starting at 3rd level, your fortitude while raging allows you to safely harness the demonic powers of the Abyss. Your access to these powers is represented by a number of Demonic Power points. Your Barbarian level determines the number of points you have, as shown in the Demonic Power Points column of the table.

You can spend these points to fuel various Demonic features. You can safely spend up to half your level worth, rounded up, of points in one use. Trying to channel more power than your fortitude can safely manage to hold, is extremely taxing and requires a Constitution saving throw DC 12+ Points spent, a failed save immediately ends your rage, and gives you a level of exhaustion.You start knowing three such features: Abyssal Strike, Immolation Aura, and Empower Wards. You learn more Demonic powers as you gain levels in this subclass.

When you spend a Demonic Power Point, it is unavailable until you finish a short or long rest, at the end of which you regain Power points equal to your constitution modifier for a short rest.A successful long rest restores all of your Demonic Power Points. You must spend at least 30 minutes of a short rest lying down, recuperating your strained constitution to regain Demonic Power Points.

Some of your Demonic Power features require your target to make a saving throw to resist the feature’s effects. The saving throw DC is calculated as follows:

Demonic power save DC = 8 + your proficiency bonus + your Constitution modifier

Abyssal Strike

Immediately after you take the Attack action on your turn, you can spend a minimum of 1 Demonic Power point to infuse one weapon strike with the crushing cold of the Abyss, adding 1d6 Cold damage. The damage can be increased by 1d6 per extra power point spent 

Immolation Aura

As an action you can spend 1 Demonic Power point point to surround yourself in the burning rage of a demon. At the start of each of your turn, each creature within 10 feet of you takes 1d6 fire damage, and flammable objects in the aura that aren’t being worn or carried ignite. A creature that touches you or hits you with a melee attack while within 10 feet of you takes 1d6 fire damage. Damage can be increased by 1d6 for every 2 extra power point spent

Empower Wards

On your turn, as a bonus action you can spend 1 Demonic Power point to empower your magical tattoos to give you damage resistance against cold, lightning, fire and poison damage until the start of your next turn.

At 6th level,  your abyssal tattoos grows, and becomes a living being, feeding off of your body, in a symbiotic relationship. Its functions depend on your path towards the powers of the Abyss. This being is mindless, and feeds off of your adrenaline and have an unearthly craving for it.
