At 1st level, a warlock gains the Otherworldly Patron feature. The following option is available to a warlock, in addition to the options offered in the Players Handbook.

The Shadow

Your patron is a powerful entity from the Shadowfell, who has the power to manipulate life and death. Oftentimes entities in the fell will make pacts with those in their dying moments, capitalizing on the vulnerability of those they act as patron for. Examples of beings like this include those shadowy figures such as the Raven Queen, though the dark forces of the Shadowfell often keep their names completely hidden.

Expanded Spell List The Shadow lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you. Shadow Expanded Spells Spell Level Spells 1st bane, inflict wounds 2nd blur, phantasmal force 3rd life transference, phantom steed 4th death ward, phantasmal killer 5th creation, destructive wave

Deathless Starting at 1st level, you gain proficiency in death saving throws, and if the result of a death saving throw you make is 20 or higher, you regain 1 hitpoint.

Cursed Resurrection Starting at 6th level, you have become an extant form of life unbound by the normal flow of existence. Whenever you are reduced to 0 hit points or die outright, you can use your reaction to force each creature of your choice within 15 feet of you to make a Constitution saving throw. On a failed saving throw, a creature takes necrotic damage equal to twice your warlock level, or half as much damage on a successful save. You then regain consciousness and gain hit points equal to the necrotic damage dealt. After using this feature, you must take a short or long rest before doing so, again.

Undead Resilience Beginning at 10th level, you gain further control over your own mortality, almost as if you are a walking corpse. You gain immunity to poison and disease, and you stop aging.
