Actions

Multiattack

The medusa makes one Constrict attack, one Final Blade attack, and one Snake Hair attack. Alternatively, it makes two Wrathful Strike attacks.

Constrict

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage, and if the target is a Medium or smaller creature, it has the grappled condition (escape DC 20). Until this grapple ends, the target has the restrained condition, and the medusa can't constrict another creature.

Final Blade

Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage plus 21 (6d6) force damage. If the target has at least one head and the medusa rolled a 20 on the attack roll, the target is decapitated and dies if it fails a DC 20 Constitution saving throw and 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 28 (8d6) force damage from the hit.

Snake Hair

Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 11 (1d10 + 6) piercing damage plus 5 (1d10) poison damage.

Wrathful Strike

Ranged Spell Attack: +12 to hit, range 120 ft., one creature. Hit: 22 (3d10 + 6) radiant damage, and the target has the blinded condition until the end of its next turn. Blinded: • A blinded creature can't see and automatically fails any ability check that requires sight. • Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage.

Spellcasting

The medusa casts one of the following spells, requiring no material components and using Wisdom as the spellcasting ability (spell save DC 20): • At will: Light, Spare the Dying, Thaumaturgy • 2/Day: Mass Cure Wounds (cast at 8th level) • 1/Day each: Blade Barrier, Divination, Greater Restoration

Petrifying Gaze (Recharge 4-6) (Bonus Action)

The medusa unleashes petrifying magic from its eyes in a 30-foot cone. Each creature in that area must make a DC 18 Constitution saving throw if it doesn't have the blinded condition. If the saving throw fails by 5 or more, the creature has the petrified condition. Otherwise, on a failed save, the creature takes 10 (3d6) force damage, begins to turn to stone, and has the restrained condition. The restrained creature must repeat the saving throw at the end of its next turn. On a failed save, it has the petrified condition, and on a successful save, the effect ends on it. The petrification lasts until the creature is freed by the Greater Restoration spell or other magic. A creature can use its reaction, if available, to shut its eyes to avoid the saving throw. If the creature does so, it has the blinded condition until the end of its next turn. Blinded: • A blinded creature can't see and automatically fails any ability check that requires sight. • Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage.
