Levistus

+8

Levistus is always entombed in ice. The ice provides 100 temporary hit points. While Levistus has these temporary hit points, he has vulnerability to fire damage. If Levistus starts his turn with no temporary hit points from the ice, he regains 100 temporary hit points.

Magical darkness doesn't impede Levistus's darkvision.

If Levistus fails a saving throw, he can choose to succeed instead.

3/DAY

Levistus has advantage on saving throws against spells and other magical effects.

Cold damage dealt by Levistus ignores resistances and immunities.

Levistus makes three Touch of Stygia or Ice Bolt attacks. He can replace one of the attacks with Blizzard (if available).

Melee Spell Attack: +15 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) psychic damage, and the target must succeed on a DC 23 Intelligence saving throw or have the stunned condition for 1 minute. The target may repeat the saving throw at the end of its turns, ending the effect on a success. A creature that succeeds on the saving throw is immune to this effect for 1 hour.

Ranged Spell Attack: +15 to hit, range 120 ft., one target. Hit: 23 (3d10 + 7) cold damage.

Levistus chooses a point he can see within 300 feet of him. Each creature in a 20-foot-radius, 40-foot-high cylinder centered on that point must make a DC 23 Dexterity saving throw. Targets take 13 (3d8) force damage plus 13 (3d8) cold damage on a failed save, or half as much damage on a successful one.
