The zombie king has advantage on saving throws against spells and other magical effects.
The zombie king is a 10th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 17, +9 to hit with spell attacks). The king can innately cast the following spells, requiring no components. Cantrip (at will): blade ward, chill touch, dancing lights, poison spray, vicious mockery • 1st level (4 slots): bane, detect evil and good, inflict wounds, sleep • 2nd level (3 slots): darkness, knock, locate object • 3rd level (3 slots): dispel magic, slow, speak with dead • 4th level (3 slots): blight, hallucinatory terrain • 5th level (2 slots): animate objects, passwall
If damage reduces the zombie to 0 Hit Points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.
The zombie king has advantage on saving throws against any effect that turns undead.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage plus 21 (6d6) necrotic damage.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 24 (6d6 + 3) necrotic damage. The target must succeed on a DC 16 Constitution saving throw or its hit point 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 hit point maximum to 0. A humanoid slain by this attack rises 24 hours later as a zombie under the king's control, unless the humanoid is restored to life or its body is destroyed. The zombie king can have no more than 20 zombies under its control at one time.
Up to eight zombies appear in unoccupied spaces within 30 feet of the zombie king and remain until destroyed. Zombies summoned in this way roll initiative and act in the next available turn. The zombie king can have up to eight zombies summoned by this ability at a time.
