As an action, you can use your channel divinity to cast a spell from your spell list up to level 5. After using your channel divinity to cast a spell above level 2, you can’t cast the same spell again with channel divinity until a long rest.
As a bonus action, you can grasp your holy symbol and vow to send your foes screaming into the afterlife. You may target a creature you can see within 30 feet of you. You deal an extra 1d6 necrotic damage to the creature whenever you hit it with an attack for 1 minute or until it drops to 0 hit points – or falls unconscious. If a creature under this effect
dies, it cannot become undead.
If you use vow of death on an undead creature, you deal an extra 1d8 damage instead of 1d6.
Additionally, you can use a bonus action on a subsequent turn of yours to mark a new creature until the 1 minute duration expires. This uses a spell slot of level 2 or higher.
You unleash the Raven Mother's divine energy, imbued with both healing and necrotic power. Choose any creature within 30 feet of you. You can
either restore a number of hit points equal to five times your cleric level, rejuvenating their spirit with the Raven Mother's healing touch, or you can unleash a burst of necrotic energy, dealing additional damage equal to 5 + twice your cleric level to the target's life force.
