The Souleater (5e Subclass)
From D&D Wiki
You've made a pact with a Souleater, a creature whom feeds on the life force of other beings. In exchange for granting you power you must harvest life force to feed their thirst. The method for harvesting life essence can differ depending on the specific type of creature you've struck a deal with. For example a pact with a vampire might grant you fangs and the ability to extract it through bites and blood, while a demon might bless you with the ability to absorb the energy of ones soul simply through touch.

Starting at 1st level you have been granted the ability to absorb life force from creatures. As an action you can preform a melee spell attack at a range of 5ft. On a hit you deal 1d6+ your Charisma modifier as necrotic damage and heal for an amount equal to half the damage dealt. This damage increases by 1d6 at 5th, 11th, and 17th levels.
At 6th level, you may spend one minute meditating to change your body into a misty form. This transformation lasts for 1 hour. While in misty form, you gain advantage on stealth checks, and can move through objects as though they were rough terrain. You have immunity to the petrified, grappled, and restrained conditions while in this state. Your movement does not provoke attacks of opportunity for the duration. You also gain resistance to bludgeoning, piercing, and slashing damage while in this state. This feature ends early if you attack or cast spells, if you choose to end it early as an action, or if you become incapacitated. If you are in a solid object when Soul Striding ends, the object expels you in the nearest open space and deals 6d6 bludgeoning damage to you. You must complete a short or long rest before you can use this feature again.
At 10th level your body has been magically fortified with the life force stolen from others, thus granting you the following traits. You gain resistance to necrotic damage. Additionally any necrotic damage you deal ignores resistance and immunity. Your hit point maximum increases by 1 per your warlock level, and continues to increase accordingly as you level.
Starting at 14th level, when you hit a creature with an attack, you can use this feature to channel your patron's power to feast on the target creature's life force. You force one target within 60ft to make a Constitution saving throw. On a failed save, the target takes 10d10 necrotic damage, half on a successful save. Once you use this feature, you can't use it again until you finish a long rest.
