Traits

• Devil’s Sight. Magical darkness doesn’t impede Arioch’s darkvision.
• Magic Resistance. Arioch has advantage on saving throws against spells and other magical effects.
• Magic Weapons. Arioch’s weapon attacks are magical.
• Regeneration. Arioch regains 20 hit points at the start of his turn if he has at least 1 hit point and isn’t taking damage from a good-aligned silvered weapon or a good-aligned spell.
• Infernal Command. Arioch can communicate telepathically with any devil he can see within 120 feet of him. In addition, while he is within 120 feet of a creature with the Devil type, he has advantage on Charisma checks made to influence the creature.

---

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

Actions

• Multiattack. Arioch makes three attacks: two with Iron Justice and one with his Bite or Tail.
• Iron Justice. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 27 (4d6 + 10) slashing damage plus 14 (4d6) necrotic damage. If the target is a creature, it must succeed on a DC 24 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. On a critical hit, Iron Justice deals an additional 4d6 necrotic damage and the target’s head is severed if it has one.
• Bite. Melee Weapon Attack: +17 to hit, reach 5 ft., one target. Hit: 19 (3d6 + 10) piercing damage plus 10 (3d6) poison damage. The target must make a DC 21 Constitution saving throw or be poisoned for 1 minute.
• Tail. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 23 (3d8 + 10) bludgeoning damage, and the target must succeed on a DC 21 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
• Infernal Flame (Recharge 5-6). Arioch exhales hellfire in a 60-foot cone. Each creature in that area must make a DC 22 Dexterity saving throw, taking 70 (20d6) fire damage on a failed save, or half as much damage on a successful one. The flames linger, igniting flammable objects that aren’t being worn or carried.

Legendary Actions

Arioch 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. Arioch regains spent legendary actions at the start of his turn.

• Teleport. Arioch magically teleports, along with any equipment he is wearing or carrying, up to 120 feet to an unoccupied space he can see.
• Command the Infernal. Arioch targets one devil he can see within 120 feet of him. If the target can hear him, it must succeed on a DC 22 Charisma saving throw or become charmed by Arioch for 1 minute. While charmed in this way, the target must obey Arioch’s commands.
• Sword Swipe. Arioch makes one attack with Iron Justice.
• Hellish Rebuke (Costs 2 Actions). Arioch causes flames to erupt around one creature he can see within 60 feet of him. The target must make a DC 22 Dexterity saving throw, taking 27 (6d8) fire damage on a failed save, or half as much damage on a successful one.

Reactions

• Parry. Arioch adds +5 to his AC against one melee attack that would hit him. To do so, Arioch must see the attacker and be wielding a melee weapon.

Summon Devils (1/Day). Arioch summons up to 9 malebranche or 12 narzugon. The summoned devils appear in unoccupied spaces within 60 feet of Arioch and act as his allies. They remain until they die or Arioch dismisses them as a bonus action.

---

Lair Actions

On initiative count 20 (losing initiative ties), Arioch takes a lair action to cause one of the following effects; Arioch can’t use the same effect two rounds in a row:

• Infernal Blaze. A 20-foot-radius sphere of hellfire erupts from a point Arioch can see within 120 feet. Each creature in that area must make a DC 22 Dexterity saving throw, taking 26 (8d6) fire damage on a failed save, or half as much on a successful one.
• Soul Chains. Chains erupt from the ground, targeting up to three creatures Arioch can see within 60 feet. Each target must succeed on a DC 22 Strength saving throw or be restrained. A creature restrained by the chains can use an action to make a DC 22 Strength check, breaking free on a success.
• Despair Aura. Arioch emits a wave of despair in a 30-foot radius. Each creature in that area must succeed on a DC 22 Wisdom saving throw or become frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Regional Effects

The region containing Arioch’s lair is warped by his presence, which creates one or more of the following effects:

• Fiery Landscape. The area within 1 mile of Arioch’s lair is scorching hot, with small fires and heatwaves periodically flaring up. Non-fiend creatures have disadvantage on saving throws against exhaustion due to heat.
• Oppressive Darkness. Darkness within 1 mile of Arioch’s lair is magical and cannot be dispelled except by a dispel magic spell of 9th level or higher.
• Infernal Whispers. Fiends within 1 mile of the lair can communicate telepathically with each other, sharing thoughts of malice and plotting under Arioch’s influence.

These effects fade within 1d10 days if Arioch is killed.

Arioch stands as a mighty and terrifying presence within the Nine Hells, wielding his infernal powers and martial prowess with the authority of a fallen king turned devil duke. Those who dare oppose him face not just his wrath but the very essence of Hell itself.

Arioch appears as a hunched backed red-skinned humanoid, dressed in tattered regal robes except his head which resembles a fierce lion wearing a filthy blood-soaked crown.

A Duke of Hell in the service of Dispater. In life he was a king, his reign began when he usurped the throne after he declared his nephew for whom he was acting as Lord Protector, was illegitimate and ineligible for the throne. The boy and his younger brother then disappeared in mysterious circumstances. Arioch’s support was eroded by rumors of his involvement in this and the death of his wife. Enraged by public speculation of his involvement in the murders he put all the counties leading scribes and printers put to death.

A descendant of a greatly diminished and exiled House, seized on his difficulties so that he could challenge Arioch’s claim to the throne. His first attempt to invade was frustrated by a storm, but at his second attempt he arrived unopposed. Marching inland, He support as he made for the palace. Arioch mustered his troops and intercepted the invaders army. A confederation of local warlords brought forces to the battlefield but held back while they decided which side it would be more advantageous to support.

Arioch divided his army, which outnumbered the invaders. He kept most of his force together and placed it under the command of an experienced general. This general took no action when signaled to assist his king, so Arioch gambled everything on a charge across the battlefield to kill the invading lord and end the fight. Seeing the king’s knights separated from his army, the warlords intervened, surrounding and killing Arioch.

Relationships

Arioch is a vassal of Dispater, serving as Dispater’s avenger. Dispater often sends Titivilus to bring orders to Arioch; Titivilus treats Arioch as his peer, and Arioch shows no hatred of Titivilus.
