Azadel, the Holy Gluttony

Angelic Aura. Azadel emanates an aura of divine power that extends 30 feet from her in every direction. Creatures within the aura that are friendly to Azadel gain a +5 bonus to saving throws and can't be charmed, frightened, or poisoned. In addition, when a creature under the effects of the aura takes damage, Azadel can choose to magically take that damage, instead of that creature taking it. This damage that Azadel takes does not transfer other effects that might accompany the damage

Divine Weapons. Azadel's weapon attacks are magical. When she hits with any weapon, the weapon deals an extra 10d8 radiant damage (included in the attack). In addition, when Azadel attacks with a weapon, she can use her Charisma modifier, instead of her Strength or Dexterity, for the attack and damage rolls.

Divine Awareness. Azadel knows if she hears a lie.

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

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

Regeneration. Azadel regains 30 hit points at the start of her turn. If she takes force damage, this trait doesn’t function at the start of her next turn. Azadel dies only if she starts her turn with 0 hit points and doesn’t regenerate.

Special Equipment. Azadel wields a magic longsword named Finality which ignores resistance to force damage. When Azadel scores a critical hit against a creature with Finality, it suffers one of the following effects (choose one or roll a d10):

1–2: Decapitation. The creature is decapitated, provided that it has a head, as per the effect of scoring a critical hit with a vorpal sword.

3–4: Arm Amputation. One of the creature's arms is cut off, provided that it is has any.

5–6: Leg Amputation. One of the creature's legs is cut off, provided that it has any.

7-10: Vital Organ Pierced. The creature takes an extra 80 slashing damage from the hit.

Azadel also wields a magic hunting rifle named Equalizer that she can wield in one hand and that ignores the reload property. It produces its own magic ammunition that is immediately destroyed after it hits or misses a target. When not in Azadel's hands, Finality and Equalizer immediately return to Azadel's possession magically. If Azadel is dead, both weapons turn to dust but reform if Azadel is resurrected.

Multiattack. Azadel makes four weapon attacks. She can replace one attack with a use of Devour Essence if she is able to.

Finality. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 18 (2d8 + 10) force damage, or 20 (2d10 + 10) when used with two hands, plus 40 (10d8) radiant damage.

Equalizer. Ranged Weapon Attack: +19 to hit, range 80/240 ft., one target. Hit: 20 (2d10 + 10) force damage, plus 40 (10d8) radiant damage. If the target is a creature that has 100 hit points or fewer, it must succeed on a DC 17 Constitution saving throw or become paralyzed until the start of its next turn.

Belch of the Heavens (Recharge 5-6). Azadel exhales celestial fire in a 60-foot cone. Each creature in that area must make a DC 27 Dexterity saving throw, taking 24 (8d6) fire damage plus 24 (8d6) radiant damage on a failed save, or half as much damage on a successful one. In addition, on a failed save, a creature becomes frightened of Azadel until the start of her next turn. 

Devour Essence. Azadel targets an unconscious or dead creature of non-good alignment within 10 feet of her. Her midsection splits open, releasing ethereal tendrils that reach out and grapple the creature. Then, a large spectral maw appears and surrounds Azadel's head, and she begins to devour the creature's body and soul. If the target is the same size as Azadel or smaller, the creature is immediately devoured by her. If the target is at least one size larger than Azadel, she cannot replace one of her attacks with this action and must use her action to devour the creature and cannot devour another creature for 1 round. A devoured creature's body is destroyed, and if it is of CR 20 or lower, its soul is swallowed and trapped by Azadel. Otherwise, the creature's soul passes on as normal. After Azadel devours a creature, the ethereal tendrils and spectral maw immediately vanish in a burst of light, and Azadel gains temporary hit points equal to the devoured creature's hit point maximum.

Redeeming Summon. Azadel attempts to purge the soul of a creature she's devoured with positive energy. When she does so, Azadel makes a Charisma (Persuasion) check against the creature, contested by the creature's Wisdom (Insight) check. If Azadel wins, the creature's alignment becomes a good alignment of the DM's choice, and the creature's body is restored in a space within 30 feet of Azadel that she chooses, and its soul is returned to its body. The creature immediately regains a number of hit points equal to half its hit point maximum, and its body is transformed into an angelic and pure version of itself. The creature is friendly towards Azadel's ally and if it is summoned into combat, it takes its turn immediately after hers.

If Azadel loses, the creature can make a DC 27 Charisma saving throw. On a success, its soul is released and passes on as normal.

Healing Touch (6/Day). Azadel touches another creature. The target magically regains 50 (10d8 + 10) hit points and is freed from any curse, disease, poison, blindness, or deafness.

Spellcasting. Azadel casts one of the following spells, requiring no material or verbal components and using Charisma as the spellcasting ability (spell save DC 27):

At will: detect evil and good, enlarge/reduce, flame strike, invisibility, nondetection

5/day each: blade barrier, locate creature, plane shift (self only), remove curse, resurrection

1/day each: circle of power, holy aura, meteor swarm (deals force and radiant damage instead of bludgeoning and fire damage)

Suppressing Shards. Azadel targets one creature she can see within 60 feet of her. That creature must make a DC 27 Charisma saving throw. On a failed save, Azadel manifests four celestial shards that surround the target and orbit around it. While these shards orbit the creature, it has disadvantage on saving throws and ability checks and its speed is halved. If a creature makes an attack roll or casts a spell, these shards explode into a burst of radiant light, dealing the target 20 (4d10) radiant damage, and the shards are destroyed. The shards turn to dust and are destroyed at the start of Azadel's turn if they didn't explode early.

Azadel can take up to three reactions per round but only one per turn.

Divine Censor (1/Round). Azadel targets a creature she can see within 30 feet of her that is casting a spell, and attempts interrupt its casting by glaring at it with divine judgement. If the spell is 4th level or lower, it fails and has no effect. If the spell is 5th level or higher, Azadel makes a Charisma check (DC 10 + the spell’s level). On a success, the spell fails and has no effect. Whatever the spell’s level, the caster is silenced and cannot speak until the start of Azadel's next turn.

Riposte. When a creature misses Azadel with a melee attack, she immediately makes a melee weapon attack against the creature.

Azadel 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. Azadel regains spent legendary actions at the start of her turn.

Warp and Strike. Azadel magically teleports, along with any equipment she is wearing or carrying, to an unoccupied space within 120 feet of her. Before or after she teleports, she can make one weapon attack.

Banishing Gaze (Costs 2 Actions). Azadel focuses her divine gaze toward one creature she can see within 120 feet of her and attempts to expel it from her presence. The target must succeed a DC 27 Charisma saving throw or be banished to a harmless demiplane. While there, the target is incapacitated. The target reappears in the space it left or in the nearest unoccupied space if that space is occupied at the start of Azadel's next turn.

Heavenly Presence (Costs 3 Actions). Azadel temporarily enhances her angelic beauty and guise, giving off an aura of celestial grandeur. Each creature that can see Azadel must succeed a DC 27 Wisdom saving throw or be charmed by Azadel until the start of her next turn. While charmed in this way, a creature regards Azadel as an ally and will fight against creature's that are hostile towards her.
