The Unliving

Death holds no sway over your patron, who has unlocked the secrets of everlasting life, although such a prize—like all power—comes at a price. Once mortal, the Undying has seen mortal lifetimes pass like the seasons, like the flicker of endless days and nights. It has the secrets of the ages to share, secrets of life and death. Beings of this sort include Vecna, Lord of the Hand and the Eye; the dread Iuz; the lich-queen Vol; the Undying Court of Aerenal; Vlaakith, lich-queen of the githyanki; and the deathless wizard Fistandantalus. In the Realms, Undying patrons include Larloch the Shadow King, legendary master of Warlock's Crypt, and Gilgeam, the God-King of Unther.

Blessing of the Dead

Starting at 1st level, you are permanently under the effects of the sanctuary spell, but only undead are affected by the spell. You also have advantage on saving throws against any disease.

Additionally, you can use an action to regain hit points equal to your Constitution modifier plus your proficiency bonus. You can put a severed body part of yours back in place when you use this feature. Once you use this feature, you can't use it again until you finish a short or long rest.

Soultap

Starting at 6th level, you can steal the vitality of others to keep yourself and your allies from death. When a spell you cast causes a non-construct creature to be reduced to 0 hitpoints, you or an ally within 30 ft. of you may gain temporary hitpoints equal to your Charisma modifier plus your proficiency bonus. You must perform a long or short rest before using this feature again.

Undead Aspect

Beginning at 10th level, you connection to your patron begins to manifest in a way specific to you and your patron. You may choose one of the following Aspects; it is recommended to pick a thematic choice for your patron, or perhaps a different Aspect that fits with your characters approach to their undead connection:

• Sanguine Aspect: Your body becomes pale and strangely lithe and has an uncanny, predatorial grace. Your movement speed increases by 5 ft. You gain proficiency in unarmed attacks, and your unarmed attacks now deals 1d4 + your Dexterity Modifier slashing damage. In addition, you can make an unarmed attack as a bonus action.
• Rotting Aspect: Your body becomes pallid and waxy, and begins to smell like an open grave. You gain resistance to poison damage, and advantage on saving throws against being poisoned. You are immune to disease. You gain access to the cantrip poison spray and can cast it as a bonus action once per rest.
• Unhallowed Aspect: You look gaunt, almost corpselike, and your mind fills with knowledge lost to time. You gain proficiency in History and Arcana. If you are already proficient in these skills, you gain expertise in them instead. Once per long rest, you may touch a dead creature and roll an Insight check (with a difficulty class set by the DM) to discover a small detail from the creature's life, such as the location of its home, if it had a connection to another creature the warlock knows or what emotions it felts as it died. 
• Spectral Aspect: A slight cold accompanies you wherever you go, and your hair and clothes sway slightly in the air. Once per rest, you may spend a reaction move through a Medium or smaller creature or an obstacle no larger than 5 ft. as if it was difficult terrain. You must be able to see the space in which you wish to move to after moving through this obstacle. In addition, once per rest, you may briefly take a spectral form as a reaction to an attack. For that attack, you gain resistance to non-magical bludgeoning, slashing and piercing damage.

After gaining your Aspect, you cannot change it unless the DM specifies a ritual, act or event that can allow you to change the Aspect.
