Andras (Archdevil)

Lord of Wrath (Recharges after a Short or Long Rest). If Andras would be reduced to 0 hit points, his current hit point total instead resets to 450 hit points, he recharges his Cone of Fire, and he regains any expended uses of Legendary Resistance. Additionally, Andras can now use the options in the “Mythic Actions” section for 1 hour. Award a party an additional 105,000 XP (210,000 XP total) for defeating Andras after his Lord of Wrath trait activates.

Rune of Wrath. Andras is infused with power of the Rune of Wrath, while infused with it, he scores a critical hit on weapon attacks on a roll of 18 or higher and if he scores a critical hit, he rolls damage dice four times, instead of twice. As long as there still exists creatures commiting the Sin of Wrath in the Multiverse, the Rune of Wrath exists. Additionally, while Beserked, Andras is surrounded by fire, granting him the following effect:

• At the start of each of Andras’ turns, each creature within 5 feet of him takes 21 (6d6) fire damage, and flammable objects in the aura that aren’t being worn or carried ignite. A creature that touches Andras or hits him with a melee attack while within 5 feet of him takes 21 (6d6) fire damage.

Devil’s Sight. Magical darkness doesn’t impede Andras´s darkvision

Legendary Resistance (5/Day). If Andras fails a saving throw, he can choose to succeed instead.

Feral Instinct. Andras has advantage on initiative rolls.

Pack Tactics. Andras has advantage on an attack roll against a creature if at least one of the Andras's allies is within 5 feet of the creature and the ally isn't incapacitated.

Reckless. At the start of his turn, Andras can gain advantage on all melee weapon attack rolls during that turn, but attack rolls against him have advantage until the start of his next turn.

Brutal Strikes. If Andras uses his Reckless feature, he can forgo any Advantage on one Strength-based attack roll of his choice on his turn. The chosen attack roll mustn’t have Disadvantage. If the chosen attack roll hits, the target takes an extra 19 (3d12) force damage, and you can cause two Brutal Strike effect of his choice. Andras has the following effect options.

• Forceful Blow. The target is pushed 15 feet straight away from Andras, and he can then move up to half his Speed straight toward the target without provoking Opportunity Attacks.
• Hamstring Blow. The target’s Speed is reduced by 15 feet until the start of Andras' next turn. A target can be affected by only one Hamstring Blow at a time—the most recent one.
• Staggering Blow. The target has Disadvantage on the next saving throw it makes, and it can’t make Opportunity Attacks until the start of Andras' next turn.
• Sundering Blow. Before the start of Andras' next turn, the next attack roll made by another creature against the target gains a +10 bonus to the roll. An attack roll can gain only one Sundering Blow bonus.

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

Hellfire. Andras ignores resistance to fire, lightning and force damage and treats immunity as resistance. Additionally, whenever Andras deals damage other than psychic or radiant, he change it to either fire, lightning or force.

Indomitable Might. If Andras' total for a Strength check or Strength saving throw is less than his Strength score, he can use that score in place of the total.

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

Innate Spellcasting. Andras´s spellcasting ability is Charisma (spell save DC 22, +14 to hit with spell attacks). Andras can innately cast the following spells, requiring no material components:

At will: Searing Smite (9th level), Hunter's Mark, Compelled Duel

3/day each: Immolation, Wall of Fire, Fire Shield (warm only)

1/day each: Fire Storm, Symbol (fear only), Delayed Blast Fireball (9th level)

Multiattack. Andras uses his Battle Roar and then makes three greataxe attacks.

Greataxe. Melee Weapon Attack: +18 to hit, reach 10 ft., one target. Hit: 23 (3d8 + 10) force damage plus 21 (5d8) fire damage. If the target is a creature other than an undead or a construct, it must succeed on a DC 17 Constitution saving throw or lose 30 (9d6) hit points at the start of each of its turns due to an exposed wound. Each time Andras hits the wounded target with this attack, the damage dealt by the wound increases by 30 (9d6). Any creature can take an action to stanch the wound with a successful DC 23 Wisdom (Medicine) check. The wound also closes if the target receives magical healing.

Cone of Fire (Recharge 4–6). Andras erupts a blast of hellfire from his hands. Each creature in a 60-foot cone must make a DC 22 Dexterity saving throw. A creature takes 54 (12d8) fire damage on a failed save and any mundane metal objects they are wearing or carrying are melted into slag and destroyed. On a successful save, a creature takes half as much damage and their equipment isn’t destroyed.

Additionally, the fire remains in that area until the end of Andras’ next turn. For the duration, that area is difficult terrain, and a creature who enters that area for the first time on a turn or ends their turn there takes 28 (8d6) fire damage.

If a creature is reduced to 0 hit points by this effect, the creature immediately dies, and its body is reduced to ash.

Battle Roar. Each creature of the Andras’ choice that is within 120 feet of him, is aware of him and can hear him must succeed on a DC 26 Wisdom saving throw or become frightened 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. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to Andras´ Battle Roar for the next hour.

Berserk (4/day). Andras enters a berserked state for 1 minute. During this time, he has advantage on Strength checks and Strength saving throws, his attacks deal an extra 13 (2d6+6) fire damage on a hit and he has resistance towards all types of damage except psychic and force.

Change Shape. Andras magically transforms into any creature that is Huge or smaller, while retaining his game statistics (other than his size). This transformation ends if Andras is reduced to 0 hit points or uses a bonus action to end it.

 Retaliation. When Andras takes damage from a creature that is within 10 feet of him, he can take a Reaction to make one Greataxe against that creature.

Andras can take 5 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. Andras regains spent legendary actions at the start of his turn.

Call of the Pack (Costs 3 Actions): Andras magically summons 3d4 Hell Hounds. The Hell Hounds appears in an unoccupied space within 60 feet of Andras and acts as Andras´s allies. The Hell Hounds remain until Andras dies or until he dismisses them as an action. 

Fury Attack: Andras attacks once with his greataxe.

Spellcasting (Costs 2 Actions): Andras casts a spell from his Innate Spellcasting trait.

If Andras´s Lord of Wrath trait has activated in the last hour, he can use the options below as legendary actions.

Ignition (Costs 2 Actions). Andras casts Immolation without consuming one of it´s daily uses and without requiring concentration.

Volcanic Orb (Costs 4 Actions). Andras evokes the flames of Phlegethos at the palm of his hand, then, condensing it into a powerful orb of magma he strikes it with full force at the ground. Each creature in a 60-foot-radius must makes a DC 26 Dexterity saving throw. A creature takes 70 (15d6 + 20) fire damage, are knocked 10 feet away from Andras in a straight line and are left prone on a failed save or half as much damage only on a successful one.

When the orb explodes, flammable objects that aren’t being worn or carried and creatures that are not immune to fire damage in the explosion start burning.
