Multiattack

The horde makes up to three claw attacks but no more than one against each target.

Claw

Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 16 (4d6 + 2) necrotic damage and the target makes a DC 12 Constitution saving throw. On a failure the target is cursed until it finishes a short or long rest or is the subject of remove curse or a similar spell. While cursed the target makes attack rolls Strength checks and Strength saving throws with disadvantage. If the target dies while cursed a new undead shadow rises from the corpse in 1d4 hours the corpse no longer casts a natural shadow and the target can't be raised from the dead until the new shadow is destroyed.
