Pact-Revenant

Gift of Undeath

You are not a normal revenant that has risen through your own will alone. instead, you have made a pact with a patron or god to uphold their desires on the planes in return for them giving you the boon of life once more. This unnatural state has allowed you to rise with a new body, identical to your original, but changed. With pale skin, and a body temperature several degrees lower than would be healthy. However, with no signs of decay or death. The body is functional, however, your blood has turned pitch black, and your wounds will leak a mist-like vapor while bleeding this black blood. Aside from this, your body functions just as it did in life.

Stench of Death

Though you appear mostly living to the naked eye, and your heart beats with black blood, in the end you are still unnatural, undead. Any abilities or spells that would detect undead will cause you to glow with such. You gain the sub-race of Undead, causing effects that would turn undead effect you as per normal. You hold a faint scent affiliated with where your soul was before your patron or god pulled you from the plane (ie. Brimstone, riverwater, etc). You are proficient in one bonus language used in the plane your soul was trapped prior.

The Dead cannot Die

You will slowly re-form from damage you suffer, the vapor-like mist turning to solid flesh as time passes. This includes if entire parts of your body are destroyed, though this will take time. You naturally regenerate 1 HP per minute, and you cannot die. Instead when you hit 0 HP you must use your action to roll a constitution saving throw, and if you roll 16 or higher you will regain consciousness at 1 HP. If you fail this DC 3 times, you will turn to vapor (keeping only your attuned equipment) and re-form in a random location within a mile radius of the spot of your death decided by the DM. This reanimation requires three days.

Spells (Revivify, Raise Dead, etc), abilities and items (Potions, Healers Kits, etc) that would bring you back from the dead or heal you have no effect on you. If the spell True Resurrection is used, and the Revenant is willing, they are broken from the pact binding it and they are raised back to their original living form.

Deathly Flesh

Due to your undead form, you hold several unique benefits. You gain immunity to the conditional effects of Exhaustion, Disease, and Poisoned, as well as Immunity to Poison damage. You are resistant to Necrotic damage as well as either fire, or cold depending on the plane that your soul originated from. You gain universal resistance against magical effects, gaining advantage on saving throws against spells and other magical effects.
