Infernal Despair. Each creature within 30 feet of Hutijin that isn't a devil makes saving throws with disadvantage.

Legendary Resistance (3/Day). If Hutijin fails a saving throw, he can choose to succeed instead.

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

Regeneration. Hutijin regains 20 hit points at the start of his turn. If he takes radiant damage, this trait doesn't function at the start of his next turn. Hutijin dies only if he starts his turn with 0 hit points and doesn't regenerate.

Spellcasting. Hutijin casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability (spell save DC 22):

At will: alter self (can become Medium when changing his appearance), detect magic, hold monster, invisibility (self only), lightning bolt, suggestion, wall of fire

3/day: dispel magic

Multiattack. Hutijin makes one Bite attack, one Claw attack, one Mace attack, and one Tail attack.

Bite. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit:15 (2d6 + 8) fire damage. The target must succeed on a DC 22 Constitution saving throw or become poisoned. While poisoned in this way, the target can't regain hit points, and it takes 10 (3d6) poison damage at the start of each of its turns. The poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Claw. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit:17 (2d8 + 8) cold damage.

Mace. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit:15 (2d6 + 8) force damage.

Tail. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit:19 (2d10 + 8) thunder damage.

Teleport. Hutijin teleports, along with any equipment he is wearing and carrying, up to 120 feet to an unoccupied space he can see.

Fearful Voice (Recharge 5–6). In response to taking damage, Hutijin utters a dreadful word of power. Each creature within 30 feet of him that isn't a devil must succeed on a DC 22 Wisdom saving throw or become frightened of him for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A creature that saves against this effect is immune to his Fearful Voice for 24 hours.

Attack. Hutijin makes one Claw, Mace, or Tail attack.

Teleport. Hutijin uses Teleport.

Lightning Storm (Costs 2 Actions). Hutijin releases lightning in a 30-foot radius, blocked only by Cover. All other creatures in that area must each make a DC 22 Dexterity saving throw, taking 18 (4d8) lightning damage on a failed save, or half as much damage on a successful one.
