Eyes of the Grave

At 1st level, you gain the ability to occasionally sense the presence of the undead, whose existence is an insult to the natural cycle of life. As an action, you can open your awareness to magically detect undead. Until the end of your next turn, you know the location of any undead within 60 feet of you that isn't behind total cover and that isn't protected from divination magic. This sense doesn't tell you anything about a creature's capabilities or identity.
You can use this feature a number of times equal to your proficiency modifier. You regain all expended uses when you finish a long rest.

Channel Divinity: Path to the Grave

Starting at 2nd level, you can use your Channel Divinity to mark another creature’s life force for termination.
As an action, you choose one creature you can see within 30 feet of you, cursing it until the end of your next turn. The next time you or an ally of yours hits the cursed creature with an attack, the creature has vulnerability to all of that attack's damage, and then the curse ends.

Sentinel at Death's Door

At 6th level, you gain the ability to impede death’s progress. As a reaction when you or an ally that you can see within 30 feet of you suffers a critical hit, you can turn that attack into a normal hit. Any effects triggered by a critical hit are canceled.
You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses when you finish a long rest.

Blessed Strikes

You are blessed with divine might in battle. Starting at 8th level, once per round, when you would deal damage to a creature with a weapon attack or a cleric cantrip, you may deal an additional 1d8 points of damage of a type appropriate for you domain (see Narrator). At 14th level, the additional damage with weapon attacks increases to 2d8 (cantrips still only deal an additional 1d8).

Keeper of Souls

At 17th level, you can seize a trace of vitality from a parting soul and use it to heal the living. When an enemy you can see dies within 30 feet of you, you or one ally of your choice that is within 30 feet of you regains hit points equal to the enemy’s number of Hit Dice.
You can use this feature only if you aren't incapacitated and once you use it, you can't do so again until the start of your next turn.
