Actions

Multiattack

The specter uses Mournful Keening if available, then makes one Hooves attack and one Reaping Scythe attack.

Hooves

Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage plus 28 (8d6) necrotic damage. If the target is a Medium or smaller creature, it must succeed on a DC 18 Strength saving throw or have the prone condition.

Mournful Keening {@recharge}

The specter utters a keening wail, calling to those close to death. Each non-Undead creature within 120 feet of the specter must make a DC 15 Constitution saving throw. On a failure, the creature hears the wail and is marked for death. A creature marked for death can't regain hit points, has disadvantage on death saving throws, and all attack rolls against it are made with advantage. This effect lasts for 1 minute or until the creature is targeted by a remove curse spell or similar magic.

Reaping Scythe

Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 12 (1d12 + 6) slashing damage plus 28 (8d6) necrotic damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw or gain a level of exhaustion.
