Archon Orphamiel

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

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

Angelic Weapons. Archon Orphamiel's weapon attacks are magical. All of his attacks and damage rolls have a +2 bonus. When he hits with any weapon, the weapon deals an extra 4d8 radiant damage (included in the attack).

Divine Awareness. Orphamiel knows if he hears a lie.

Enough! If Orphamiel would be reduced to 0 hit points, he drops to 1 hit point instead and declares that the players have bested him.

Multiattack. Archon Orphamiel makes two melee attacks. Instead of one attack, he can use any of his other actions.

Angelic Greatsword. Melee Weapon Attack: +16 to hit, reach 10 ft., 1 target. Hit: 24 (4d6 + 10) slashing damage plus 18 (4d8) radiant damage.

Pommel Strike. Melee Weapon Attack: +16 to hit, reach 5 ft., 1 target. Hit: 17 (2d4 + 10) bludgeoning damage plus 18 (4d8) radiant damage.

Blinding Flash (1/Day). Archon Orphamiel's greatsword flashes with incredibly bright light. All creatures within 300 ft. must make a DC 19 CON save or take 45 (10d8) radiant damage and be blinded, half if saved. At the end of each of their turns, the blinded creatures can repeat the save, ending the condition on a success.

Light-Forged Twin (1/Day). Archon Orphamiel summons a spectral copy of himself, which appears to be made of sunlight. He can command this copy by using his bonus action. The Light-Forged Twin is an intangible object and it can only be destroyed by defeating Orphamiel.

Purging Light (3/Day). Archon Orphamiel targets any magical effect or magically conjured creature he can see and destroys it with a flash of sunlight.

Healing Touch (4/Day). Archon Orphamiel touches another creature. The target magically regains 50 (10d8 + 5) hit points and is freed from any curse, disease, poison, blindness, or deafness.

Command Twin. Archon Orphamiel issues a command to his light-forged twin. As part of the command, the twin can move (it has the same movement speed as Archon Orphamiel) and attack twice using its Light-forged Greatsword.

Light-forged Greatsword. Melee Weapon Attack: +14 to hit, reach 10 ft., 1 target. Hit: 33 (8d6 + 5) radiant damage.

Archon Orphamiel 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. Archon Orphamiel regains spent legendary actions at the start of his turn.

Teleport. Archon Orphamiel magically teleports, along with any equipment he is wearing or carrying, up to 10 miles.

Pommel Strike. Archon Orphamiel uses his Pommel Strike action.

Distracting Flash. Archon Orphamiel points his hand at a single foe's eyes and hits them with a blinding and distracting flash of light. The creature must make a DC 19 Constitution save or it is blinded until the end of its next turn, and loses concentration on any spell it is concentrating on.

Divine Retribution (Costs 2 Actions). Archon Orphamiel conjures a radiant image of his sword, floating above a creature's head. Starting next round, on initiative count 0, the sword falls down, forcing any creature in a 3x3 square cube below it to make a DC 19 Dexterity saving throw, taking 90 (20d8) radiant damage and fall prone on a failed save, half if saved.
