Human Death Acolyte

When an enemy succeeds on a death saving throw while within 30 feet of three or more acolytes who aren't incapacitated, the success instead counts as a failure, and if the roll was a 20, the enemy doesn't regain hit points.

When the acolyte makes or joins an attack that's made with advantage, the attack deals an extra 1 damage per acolyte who made or joined the attack.

If the acolyte takes damage from an attack or as the result of a failed saving throw, their hit points are reduced to 0. If the acolyte takes damage from another effect, they die if the damage equals or exceeds their hit point maximum; otherwise they take no damage.

Melee Spell Attack: +4 to hit, reach 5 ft., one creature. Hit: 2 necrotic damage, and if this attack was made by more than one acolyte, a creature of the acolytes' choice within 30 feet of them regains 1 hit point per acolyte who joined this group attack.

Ranged Spell Attack: +4 to hit, range 30 ft., one target. Hit: 2 necrotic damage.
