Apocryphal/Galtich the Angelic Demon

• Immutable Form (Angel Trait): Apocryphal is immune to any spell or effect that would alter its form.

• Immunity to Imprisonment (Angel Trait): Apocryphal cannot be sealed away or trapped through non-magical or magical barriers, or even imprisoned.

• Aura of Illumination and Dispelling (Angel Trait): Apocryphal has an aura that illuminates and dispels magical darkness, invisibility, and illusions in a 120-foot radius.

• Aura of Truth (Angel Trait): All Angels have an active aura of truth preventing lies from being spoken within 120 feet.

• Immunity to Certain Attacks (Angel Trait): All Fiends, Undead, and all non-Good-Aligned Characters cannot hit Apocryphal. Constructs and other Angels ignore this effect. (Note: As Apocryphal is a Fiend, this is a bit paradoxical, but since you designated it as an Angel, I will include this trait.)

• Hellish Resilience (Demon Trait): Apocryphal heals when someone is frightened.

• Terror's Might (Demon Trait): Apocryphal autohits and auto crits enemies who are frightened.

• Fog Form (Demon Trait): Apocryphal can switch between its normal form and an incorporeal fog form as a bonus action. While in Fog Form, anyone who breathes and starts their turn inside of their fog takes 9d6 poison damage (PB +9). Apocryphal reverts to its normal form as a bonus action.

• Fright Hunter (Demon Trait): Apocryphal can always see who is frightened and can teleport to a frightened target on its turn.
  
  

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

Multiattack. Apocryphal makes four attacks.

Large Longsword. Melee Weapon Attack: +20 to hit, reach 10 ft., one target. Hit: 55 ($\text{3d8}+41$) slashing damage, or 58 ($\text{3d10}+41$) slashing damage if used with two hands, plus 13 ($\text{3d8}$) poison damage.

Eldritch Warbow. Ranged Weapon Attack: +16 to hit, range 150/600 ft., one target. Hit: 42 ($\text{2d4}+38$) piercing damage plus 13 ($\text{3d8}$) poison damage, and the target must succeed on a DC 27 Constitution saving throw or be poisoned. The poison lasts until it is removed by the Lesser Restoration spell or similar magic. 

Chains of the Divine. Ranged Weapon Attack: +20 to hit, range 40/80 ft., one target. Hit: 49 ($\text{2d6}+10$ bludgeoning damage plus $\text{8d8}$ radiant damage). If the target hit is a creature, it must make a DC 27 Strength saving throw or be restrained. The target can repeat the saving throw at the start of each of their turns, ending the effect on themselves on a success. Apocryphal can manifest multiple chains and restrain multiple creatures. The chains are magically attached to Apocryphal and have 15 AC, 100 hit points and immunity to necrotic, poison and psychic damage. 

Radiant Burst (Recharge 4-6). Apocryphal releases a burst of divine energy around itself. Each creature within 30 feet of the Angel lord must make a DC 27 Dexterity saving throw. On a failed save, a creature takes 54 ($\text{12d8}$) radiant damage and is knocked prone. On a successful save, the creature takes half as much damage and isn't knocked prone.

Healing Touch (4/Day). Apocryphal touches another creature. The target magically regains 51 ($\text{8d8}+15$) hit points and is freed from any curse, disease, poison, blindness, or deafness. 

Eldritch Smite. On a successful hit, Apocryphal can deal an extra 23 ($\text{5d8}$) force damage and knock them prone.

Form Shift. Apocryphal can switch between its normal form and its incorporeal Fog Form (Demon Trait).

Parry. Apocryphal adds 4 to its AC against one melee attack that would hit it. To do so, she must see the attacker and be wielding a melee weapon.

Apocryphal 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. Apocryphal regains spent legendary actions at the start of its turn.

Teleport. Apocryphal magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space it can see.

Judgement (Costs 2 Actions). Apocryphal makes one Chains of the Divine attack against each creature within range. On a hit, a target takes no damage.

Heal Self (Costs 3 Actions). Apocryphal magically regains 90 Hit Points.

When Apocryphal reaches 0 Hit Points, it regains 400 hit points and now has the following passive trait:

Aura of Distortion. Any enemy within 120 feet of Apocryphal who enters, starts, or ends their turn there takes $\text{4d10}$ Necrotic/Psychic/Force damage (Roll a $\text{d6}$ to see which damage: 1-2 Necrotic, 3-4 Psychic, 5-6 Force). On top of that, anyone who starts their turn in the Aura of Distortion must roll a DC 27 Wisdom saving throw or be affected by the confusion spell. They can repeat this saving throw at the start of their turn.

• Once they fail, they must roll a $\text{d10}$ to determine their Behavior:

  • 1: The creature uses all its movement to move in a random direction. To determine the direction, roll a $\text{d8}$ and assign a direction to each die face. The creature doesn’t take an action this turn.

  • 2–6: The creature doesn’t move or take actions this turn.

  • 7–8: The creature uses its action to make a melee attack against a randomly determined creature within its reach. If there is no creature within its reach, the creature does nothing this turn.

  • 9–10: The creature can act and move normally.
