Path of Horror

You are a cursed soul! You carry an aura of death and decay. You may seem to be an emotionless being and otherworldly in appearance and/or behavior, but your rage is frightening. You may be an undead who even Death couldn't stop, or an evil spirit has chosen to haunt you. Either way you use manifestations of nightmares and shadows to scare creatures and sap them of their lifeforce.

Hand of Darkness

The Being that haunts you manifests itself as a shadowy hand or tentacle coming from your back. This shadowy hand is only perceivable in your peripheral vision. A number of times equal to your proficiency modifier per long rest you may....

• Use the Hand of Darkness as if you had casted the spell Mage Hand. While the duration is the same, the reach of the hand is reduced to 15 ft but can lift the same amount of weight as you can. OR.....
• Have the Hand of Darkness help you in social situations by giving you advantage on Intimidation checks, and you may use your Constitution modifier instead of Charisma modifier for persuasion, deception, and Intimidation checks.

 During your rage, The Hand has a 10 Ft. reach. As a Bonus Action, the hand may force a creature to make STR. Saving Throw on failure the target is grappled and knocked prone, and when they fail their attempt to break the grappled condition, they take 1d4 necrotic or cold damage. Or as a Bonus Action the Hand can force a WIS. saving throw on a failure, they take 1d6 necrotic or cold damage.

Hands of Darkness

The connection between the Being and you have grown and the Being haunting you grants you more powers. Now you get an additional Hand of Darkness. On your Bonus Action you can control both Hands each Hand can choose to grapple or attack a creature and can target the same creature.  The hands also provide additional bonuses outside of combat too. A number of times equal to your proficiency modifier per long rest you may...

• Use the Hands of Darkness to gain a climb speed equal to your walking speed.  You may also climb as if you have the benefits of the Spider Climb spell. And use the Hands of Darkness as the anchor point.
• The Hands of Darkness cover you granting you invisibility while in darkness until you leave the darkness or attack a creature. If not in darkness you gain expertise in the Stealth skill for one minute.

Visage of the Void

The being's influence on you grows. It can now manifest more of itself when you rage. When you rage you gain one of two abilities...

 Wails of Doom

The Being howls through you causing all creatures in a 30 ft radius around you that can hear you makes a WIS Saving Throw or becomes Frightened of you.

Shield of Shadows

The Being's body encases you in shadows to protect you and lashes out at those who harm you. You gain temporary hit points equal to your Barbarian level and if a creature hits you with a melee attack while you have temporary hit points, they take necrotic or cold damage equal to your barbarian levels. This damage can be triggered even if you have temporary hit points not granted to you by this class feature.

Improved Hands of Darkness

Your bond and understanding of The Being have allowed you to use more of its strength in combat. The Hands of Darkness gain an increased reach of 15 ft. Also, the damage the Hands do increase from 1d4 to 1d6 and from 1d6 to 1d8 for their respective abilities.

Grasping Shadows

Now even your shadows grow malicious. You gain a 10 ft aura that causes the ground around you to become magical difficult terrain as your shadows pull and tug on creatures that are in the aura. As an Action, you can command the shadows to restrain the creatures around you. All creatures in your aura must make a STR. saving throw or become grappled.

Vessel of the Void

The Being begins to go from haunting you to using you as a vessel. As such you no longer eat, drink, sleep or breath as the Being resides inside you. You are also immune to spells and magical effects that cause you to sleep or require you to be asleep and you have advantage on saving throws to be frightened. 

Avatar of Nightmares

You have become an avatar for the monster inside you this changes your appearance and may even change your alignment. When in Rage you let the monster take over and gain the appearance of the monster. The also comes many benefits and abilities.... 

Unfathomable Horror

Creatures that would be immune to the frightened condition now have advantage of saving throws to be frightened of you and those who didn't have immunity now suffer disadvantage on saving throw to be frightened of you as you take on the form of the Being and can tap into anything's fears.

Nightmare-Fueled Strikes

Targets of the Hands of Darkness and of Grasping Shadows must make a Wis. Saving Throw or becomes frightened of you, as now even your touch become fear inducing.

Malicious Opportunist

Now when you kill a creature frightened of you, you gain temporary hit points equal to your proficiency modifier.

Aura of Nightmares

Creatures do not gain the benefit of a long rest when you are within 30 ft of them and suffer great nightmares and night terrors when they sleep in your presence as The Being within you feasts on their fears.
