Innate Spellcasting. The molydeus’s innate spellcasting ability is Charisma (spell save DC 22). It can innately cast the following spells, requiring no material components:

  • At will: dispel magic, polymorph, telekinesis, teleport

  • 3/day: lightning bolt

  • 1/day: imprisonment

Legendary Resistance (3/Day). If the molydeus fails a saving throw, it can choose to succeed instead.

Magic Resistance. The molydeus has advantage on saving throws against spells and other magical effects.

Magic Weapons. The molydeus’s weapon attacks are magical.

Actions

Multiattack The molydeus makes three attacks: one with its weapon, one with its wolf bite, and one with its snakebite.

Demonic Weapon Melee Weapon Attack: +16 to hit, reach 15 ft., one target. Hit: 20 (2d10 + 9) slashing damage. If the target has at least one head and the molydeus rolled a 20 on the attack roll, the target is decapitated and dies if it can’t survive without that head. A target is immune to this effect if it takes none of the damage, has legendary actions, or is Huge or larger. Such a creature takes an extra 6d8 slashing damage from the hit.

Wolf Bite Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 16 (2d6 + 9) piercing damage.

Snakebite Melee Weapon Attack: +16 to hit, reach 15 ft., one creature. Hit: 12 (1d6 + 9) piercing damage, and the target must succeed on a DC 22 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 transforms into a manes if this reduces its hit point maximum to 0. This transformation can be ended only by a wish spell.

The molydeus can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The molydeus regains spent legendary actions at the start of its turn.
