Path of the Undying

Barbarians who walk the Path of the Undying rarely choose it for themselves. They are set on this course by the heavy hand of destiny. Undying barbarians all possess a soul that has crossed into death, then been pulled back into the world of the living by extraordinary magical means. Returning from true death is a turbulent process that shatters a soul, then reforges it into something entirely new. Creatures in possession of such souls are often psychically scarred by the experience, but they gain a measure of mastery over death. Those who walk this path can’t be pulled into death until their destiny-the reason their soul returned-is fulfilled.

Defy Death

Starting at 3rd level, whenever you begin your turn with a number of hit points less than your barbarian levels, you may expend one of your Hit Dice to recover hit points equal to the number rolled plus your Constitution modifier (no action required). You can use this feature while unconscious, but not if you are dead. 5

Soul of Wrath

Starting at 3rd level, you become possessed by supernatural wrath when you enter your rage. While you are raging, once during each of your turns when you hit a creature with an attack roll, you can force them to make a Wisdom saving throw with a DC equal to 10 + your proficiency bonus. On a failed save, the creature is frightened of you until the end of your next turn.

Additionally, you deal an extra 1d6 psychic damage whenever you hit a creature that is frightened of you with a weapon attack.

Feast of Suffering

At 6th level your soul consumes ailments that hinder your physical form. As a bonus action, you can end one condition afflicting you and gain temporary hit points equal to half your barbarian level (rounded down). These temporary hit points last for 1 minute.

Vengeance Snare

At 10th level, while you are raging you can use a bonus action to project your wrathful soul outwards. When you do so, all creatures of you choice within 30 feet of you must succeed on a Wisdom saving throw (DC equal to 10 + your proficiency bonus) or become frightened of you for 1 minute or until they are more than 60 feet away from you. If a creature was already frightened of you when they fail this saving throw, they are also paralyzed until the end of your next turn.

Once you use this feature, you can’t use it again until you finish a long rest.

Rejected by Death

Starting at 14th level, death no longer desires you. If you die and your body is destroyed, your soul remains. After 24 hours, your soul inhabits and animates another humanoid corpse on the same plane of existence, and the body returns to life with all your hit points. Upon awakening, you recall your former life and experiences. You retain the capabilities you had in your original form, except you exchange your original race for the new one (if different than your previous form) and change your racial traits accordingly.
