Path of the Damned

Burning within the lowest of the planes, filled to bursting with the lost souls and evil creatures that long to torment the living, is a place of fire and death. The simmering resentment and fury that broils within can rarely find release, channeling through creatures that harbour similar feelings of hatred and wrath. Corrupting those that wield it, it instills a rouring desire to tear the world asunder, to lay waste to everything they see, and to tear those they detest the most limb from limb. Their forms share a similar warped state when focusing their anger, becoming twisted and repugnant like the loathing demons they draw from.

Hatred Manifest

Starting at 3rd level, you can manifest your loathing as an agonizing curse. As a bonus action, you can choose a creature within 60 feet of you, that creature becoming the target of your detestment. This appears as a brand only you and creatures that can detect magic can see, the design being determined by you. You deal an additional 1d6 damage against that creature, and the creature has disadvantage on opportunity attacks against you. You can only have one target at a time, and the curse lasts until the creature dies or until you use a bonus action to move it to another creature. The damage increases when you reach certain levels in this class, increasing to 2d6 at 10th level, 3d6 at 15th level, and 4d6 at 20th level.

You can use this ability a number of times equal to your proficiency bonus per long rest. If you finish a long rest while a creature remains cursed, you do not gain that use back.

Additionally, you gain proficiency in Charisma (Intimidation), and learn to speak, read and write Abyssal.

Corrupted Vessel

Also at 3rd level, your form is more malleable, twisting and altering your form when you rage. Choose one corruption from the list below. When you rage, you will gain that ability. When you reach 6th level, 9th level, 12th level, 15th level, and finally 18th level, you may choose another corruption. You will gain additional, more powerful options as you gain levels in this class. You can choose not to activate one or all of these when you begin your rage.

Beast of Destruction

Stocky horns burst from your skull, broad and curled at the tips. If you hit a creature with a melee attack after moving at least 15 feet, that creature takes an additional 1d10 force damage. In addition, you deal double damage to objects and structures.

Cambion Wings

Bat-like wings protrude from your back, coated in red scales and pulsing with black veins. You gain a flying speed of 50 feet.

Fetid Aura

You produce a wretched stench that clings to your foes, filling their lungs with pungent poison. Hostile creatures that start their turn within 10 feet of you must make a Constitution saving throw (DC equal to 8 + your Constitution modifier + your proficiency bonus) or be Poisoned until the start of their next turn.

Fist from Below

You sprout a bloody and malformed arm beneath one of your others, thick bones protruding from the knuckles. When you take the attack action, you can make an extra attack with this arm as a part of the same action. This arm can wield a weapon, but only ones with the Light property. Attacks with this arm have their range increased by 5 feet.

Grim Cloak

A dark, flowing robe appears around you, as black as the midnight sky and reminding many of the avatars of death. As a bonus action, you can teleport up to 30 feet to an unoccupied space you can see.

Hound of Hell

Your legs and feet alter, appearing similar to that of a Hell Hound. Your movement speed increases by 10 feet, and you are not affected by nonmagical difficult terrain. When you move at least 20 feet and make a melee attack against a creature, they must make a Strength saving throw (DC equal to 8 + your Strength modifier + your proficiency bonus) or be knocked Prone.

Impish Hide

Your skin congeals like blood and gains a reddish hue, as thick as dwarven steel. You gain resistance to all damage except radiant and psychic.

Masterful Presence

The very air around you grows heavier, your presence becoming one of intimidation and inspiration. Any ally within 20 feet of you can add your Strength modifier to any ability check or saving throw. Additionally, hostile creatures have disadvantage on saving throws against being Frightened while within 20 feet of you.

Razor Spines

A thick, lizard-like tail unfurls from your back, coated in spines as thin as needles. As a bonus action you can fire one of these spines, dealing 1d8 + your Strength modifier magical piercing damage to a creature within a short range of 20 feet, and a long range of 80 feet.

Glimpse of Evil

At 6th level, your eyes take on a more sinister appearance, pupils turning to dark slits surrounded by a fiery glow. You gain darkvision, and can see normally in darkness, both magical and nonmagical, to a distance of 120 feet.

In addition, you can cast See Invisibility a number of times equal to your proficiency bonus per long rest. You can cast it while raging.

Abhorrent Feast

At 10th level, your hateful curse can capture droplets of their life force when they fall. When a creature affected by your Hatred Manifest dies, you gain hit points equal to your Constitution modifier + your Proficiency Bonus.

In addition, you become immune to being Frightened and Charmed.

The Devil you Know

At 14th level, the darkness within your soul breaks loose, permanently altering your form. Your creature type becomes Fiend, if it isn't already. When a celestial, elemental or fiend creature attacks you, that creature must make a Wisdom saving throw against an Intimidation check. On a failed save, the creature must choose a different target, or the attack automatically misses. On a successful save, the creature is immune to this effect for 24 hours. The creature is aware of this effect before it makes its attack against you.

In addition, you learn to sense your curse, always knowing how far and what direction the creature affected by your Hatred Manifest is from you, unless they are on a different plane. You also gain immunity to fire, poison and the Poisoned condition.
