Auriel

Divine Awareness. The solar knows if it hears a lie.

Innate Spellcasting. The solar's spellcasting ability is Charisma (spell save DC 25). It can innately cast the following spells, requiring no material components:

At will: detect evil and good, invisibility (self only)

3/day each: blade barrier, dispel evil and good. 

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

Multiattack. Auriel can make two Greatsword Attacks or four Longsword Attacks

Greatsword. Melee Weapon Attack. (Hit: +15, Reach 10 ft) (Damage: 2d10 Slashing Damage + 2d8 Radiant Damage.) 

Longsword. Melee Weapon Attack. (Hit: +15, Reach 5 ft) (Damage: 3d8 Slashing Damage + 2d8 Radiant Damage.)

Healing Touch (4/Day). The solar touches another creature. The target magically regains 40 (4d10) HP. 

The solar 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. The solar regains spent legendary actions at the start of its turn.

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

Searing Burst (Costs 2 Actions). The solar emits magical, divine energy. Each creature of its choice in a 10-foot radius must make a DC 23 Dexterity saving throw, taking 14 (4d6) fire damage plus 14 (4d6) radiant damage on a failed save, or half as much damage on a successful one.

Blinding Gaze (Costs 3 Actions). The solar targets one creature it can see within 30 feet of it. If the target can see it, the target must succeed on a DC 15 Constitution saving throw or be blinded until magic such as the lesser restoration spell removes the blindness.
