Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 29 (4d10 + 7) necrotic damage and the creature must succeed at a DC 22 Constitution saving throw or be cursed with fly rot. While cursed with fly rot, the creature can't regain hit points and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. If the creature is reduced to 0 hit points by the fly rot, it dies and its body turns to a swarm of flies. The curse lasts until removed by the remove curse spell or other magic.
