Vampiric Boon. When the priest deals necrotic damage to any creature, the priest gains a number of temporary hit points equal to half that necrotic damage. The priest’s speed also increases by 10 feet.

Tattoo of Osybus. If the priest drops to 0 hit points, roll on the Boons of Undeath table for the boon the priest receives. The priest dies if it receives a boon it already has. If it receives a new boon, it revives at the start of its next turn with half its hit points restored, and its creature type is now Undead.

To prevent this revival, the Tattoo of Osybus on the priest’s body must be destroyed. The tattoo is invulnerable while the priest has at least 1 hit point. The tattoo is otherwise an object with AC 15, and it is immune to poison and psychic damage. It has 15 hit points, but it regains all its hit points at the end of every combatant’s turn.

Ice Scythe.

Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 15 (3d10+ 15) slashing damage plus 6 (1d12) cold damage. A creature hit by this scythe has their constitution score reduced by 1d4 until the creature finishes a long rest. If their score reaches zero, they die and become a zombie under Coles permanent control.

Siphon.

Melee Spell Attack: +14 to hit, reach 5 ft., one target. Hit: 23 (4d8 + 7) necrotic damage. Cole regains an amount of hitpoints equal to the damage dealt. If this kills a creature, he regains twice the hitpoints.

Pitch Black.

Cole spends a 5th level spell slot, and causes his armor to release masses of hazardous shadow. A massive cloud of magical darkness appears where he stands with a radius of 60 ft. Cole can choose for up to 10 creatures to be able to see through the darkness automatically. As an action while the dark cloud exists, he can cause creatures of his choice inside the cloud to regain 2d12 hitpoints.

Soul Tattoo (Recharge 5–6)

 The priest touches one of the Soul Tattoos on its body. The tattoo vanishes as the trapped soul manifests as a shadowy creature that appears in an unoccupied space the priest can see within 30 feet of it. The creature has the size and silhouette of its original body, but it otherwise uses the stat block of a shadow.

The shadow obeys the priest’s mental commands (no action required) and takes its turn immediately after the priest. If the creature is within 5 feet of the priest, it can turn back into a tattoo as an action, reappearing on the priest’s flesh and regaining all its hit points.

Undead Parry. If Cole is within 5 ft. of an undead creature he controls, he can use his reaction to instead have the attack target this creature.
