Path of the Relentless

Barbarians who walk the deadly Path of the Relentless have rejected death in many ways. During their childhood, they may have been tested on and revived after dying the dangerous injections used on them, or during adulthood where they were killed in some way and brought back to life without magic. People have tried to send Barbarians on this path back to the realm of the dead, though, they are always unable to.

Rejuvenation

Starting when you take this path at level 3, the instant you fall unconscious, you can consume a charge of your rage to cause a bolt of lightning to strike you're unconscious body, and heals you by 1d4 HP. If you were already raging before using this, the same effects happens as if you used this effect and your rage stops.

The amount your healed increases to 2d6 at Level 6, 3d8 at Level 10, and 4d12 at Level 14.

Pursuit of Blood

Beginning at 6th level, you gain the ability to disappear into mist as a bonus action. You then can choose a target within 20 ft. of your original position and appear in front of them. You can use a number of times equal to your proficiency modifier per long rest.

Frightening Hemorrhage

Beginning at 10th level, while raging, the first time you hit a target on your turn, you cause them to become frightened.

Indomitable

Starting at 14th level, you gain temporary hit points equal to your maximum hit points. These temporary hit points go away when you stop raging.
