Celestial Weapons. The angel’s weapon attacks are magical. Whenever the angel hits a target with a weapon attack, the weapon deals an extra 4d8 radiant damage (included in attack). The angel may use its Charisma modifier for its weapon attack and damage rolls however, it must use the same attribute for both.

Divine Awareness. The angel knows if it hears a lie, and has advantage on Wisdom (Insight) checks.

True Form. The angel can choose to magically conceal its divine nature so that it cannot be detected by magic such as the detect evil and good spell or a Paladin's Divine Sense. When the angel conceals its true form, it takes the form a medium humanoid, its statistics other than its speed and AC remain unchanged. The angel’s true form is revealed when it chooses to reveal itself, or when its hit points are reduced to 0 while in its concealed (humanoid) form. When the angel’s true form is revealed, its Angelic Armor ( +2 Plate), and Sword of Heaven ( +2 Greatsword) are magically summoned to it and equipped (included in statistics); both items are crafted from mithral and radiant-gold, and cannot lose their magical properties by any means other than destruction.

Cleansing Truth (1/day). When the angel’s true form is revealed, it immediately regains hit points equal to half of its hit point maximum, and gains the secondary benefits of its Healing Touch feature.

Sentinel Sword. Whenever the angel is in a space within 5 ft of its sword while it is animated (see Sword of Heaven), all weapon attacks made against the angel have disadvantage. If an attack is prevented by this feature, and the attack falls short of the angel’s AC by a margin of 1 or 2; the attacker rolls damage as if the attack was successful, but as if the attack was being made against an object. The sword then takes damage equal to the damage rolled, subject to the sword’s characteristics.

Innate Spellcasting. The angel’s spellcasting ability is Charisma (spell save DC 19, +11 attack bonus). It can innately cast the following spells, requiring only verbal components:

At will: detect evil and good, invisibility (self only), sacred flame (*3d8 radiant damage), shield of faith.

3/day each: call lightning, dispel magic, mass healing word.

2/day each: death ward, fire shield, staggering smite (*radiant damage).

1/day each: flame strike, dispel evil and good, raise dead.

Magic Fortitude. The angel has advantage on saving throws against spells and other magical effects, and it cannot be put to sleep by any means other than a wish spell.

Heavenly Throes. If the angel is reduced to 0 hit points while in its True Form, the angel is destroyed and its body erupts in a blinding flash of searing light. Each creature within 30 feet of the angel must make a DC 19 Constitution save, taking 24 (7d6) radiant damage on a failed save and only half as much damage on a successful save. Creatures that fail the save by 5 or more are blinded for 1 minute. When this occurs, the angel’s summoned armor and sword are destroyed along with it.

Multiattack. The angel makes one attack while in its humanoid form or two attacks in its true form; one of the angel’s true form attacks may be replaced with sacred flame.

Slam. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) bludgeoning damage plus 18 (4d8) radiant damage. Instead of dealing damage, the angel can grapple the target (Escape DC 22).

Mace. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) bludgeoning damage plus 18 (4d8) radiant damage.

Sword (True Form Only). Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 18 (3d6 + 8) slashing damage, plus 18 (4d8) radiant damage. The angel cannot use this attack while its sword is animate.

Healing Touch (4/Day). The angel touches another creature (humanoid form only); or targets a creature it can see within 30 feet (true form only). The target magically regains 34 (6d8 + 6) hit points and is freed from any curse, disease, poison, blindness, or deafness.

Sword of Heaven (True Form only). The angel releases its held sword, which hovers in-place in an unoccupied space within 5 feet of the angel. The sword becomes animate and acts immediately, following the angel’s mental commands; while the sword is within 100 feet of the angel, the angel can command the sword to fly up to 50 feet and make one (flying sword) attack against a target the angel can see. The angel may use a bonus action on its turn to command the sword, including the bonus action used in which the sword becomes animate. Regardless of the distance between them, the sword instantly “blinks” to the angel’s hand if commanded to do so (no sight required) and then ceases to be animate. At the start of the angel’s turn, if its sword is animate and more than 100 ft away, the sword moves up to 50 ft toward the angel, flying if it can; or teleporting if unable to do so (ending its movement in an unoccupied space). If no unoccupied spaces are available for the sword to move to, it hovers in place and takes the Dodge action, the sword vanishes after 1 hour if it isn’t called by the angel or if the sword cannot reach the angel otherwise. While animated in this way the sword has an AC of 22, 90 hit points, immunity to radiant damage and it ignores the first ten points of bludgeoning, piercing, or slashing damage it takes from any source (minimum of 0). If the sword is reduced to 0 hit points while it is animated in this way, it is destroyed and the angel must complete a prayer-ritual which takes 8 hours to complete before it can create a new one.

Flying Sword (Sword of Heaven). Ranged Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 15 (2d6 + 8) slashing damage plus 18 (4d8) radiant damage.

Radiant Reposte (True Form Only). When the angel takes damage from a melee attack, it can use its reaction to make one melee weapon attack against the attacker. Alternatively, if the angel takes damage while its Sword of Heaven is in a space adjacent to both the angel and the source of the damage (the attacker); the angel can use its reaction to command its sword to make one attack against the attacker with Advantage.

While in its True Form, the angel can take 3 legendary actions, choosing from the options below, and only at the end of another creature's turn. The angel regains its spent legendary actions at the start of its turn.

Smite. The angel makes one weapon attack; or commands its sword of heaven to make one flying sword attack.

Heavenly Step. The angel magically teleports to an unoccupied space it can see within 50 feet.

Burning Gaze. The angel targets one creature it can see within 30 feet. If the target can see the angel, the target must succeed on a DC 19 Constitution saving throw. On a failure, the target takes 18 (4d8) radiant damage and is set on fire. While it is on fire, a creature takes 9 (2d8) radiant damage at the start of each of its turns, any equipment the creature is wearing or carrying are unharmed by the radiant flames. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success. If the target succeeds on its initial saving throw, it takes only half as much radiant damage and is not set on fire. Once used, the angel cannot use this lair action again until the start of its next turn.
