Multiattack

The lord zombie makes two slam attacks. It can use its Life Drain in place of one slam attack.

Slam

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage.

Life Drain

Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) necrotic damage. The target must succeed on a DC 16 Constitution saving throw or its hp maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hp maximum to 0. A humanoid slain by this attack rises 24 hours later as a zombie under the lord's control, unless the humanoid is restored to life or its body is destroyed. The lord can have no more than twenty zombies under its control at one time.
