Innate Spellcasting. Kaguya-Hime's spellcasting ability is Charisma (spell save DC 17). She can innately cast the following spells, requiring only verbal components:

At will: charm monster (5th level), charm person (5th level), dancing lights, guiding bolt (6th level), misty step, moonbeam (6th level), prayer of healing (4th level)

1/day each: geas (8th level), mass heal, reincarnate

Magic Resistance. Kaguya-Hime has advantage on saving throws against spells and other magical effects.

Legendary Resistance (3/Day). If Kaguya-Hime fails a saving throw, she can choose to succeed instead.

Moonshadow. While Kaguya-Hime is on the material plane, she is immune to physical attacks.

Serenity. Kaguya-Hime is naturally surrounded by an aura of tranquility. She has the effect of a sanctuary around her at all times. The saving throw DC is 15.

Divine Retribution. Kaguya-Hime's race is beloved by the lunar deities, and any creature who tries to attack them will be punished in the name of the moon. Whenever a creature hits Kaguya-Hime with an attack or spell, that creature takes psychic damage equal to half the damage caused to her (rounded up) if she is not incapacitated.

Moon Healing (3/Day). Kaguya-Hime touches another creature. The target magically regains 40 (8d8 + 4) hit points and is freed from any curse, disease, poison, blindness, or deafness. Escalation. Kaguya-Hime can consolidate all three of her healing charges into a single casting of true resurrection.

Moon Princess Halation. A radiant glow and sparkles of positive energy emit outward from Kaguya-Hime in a sphere with a 30-foot radius. All non-good creatures in the sphere must make a DC 15 Constitution saving throw, taking 22 (4d8 + 4) radiant damage and becoming stunned on a failed save, or half as much damage on a successful one. Evil creatures have disadvantage on the saving throw. Good creatures in the sphere take no damage and are instead healed by the sparkles' energy for 22 (4d8 + 4) hit points.

Kaguya-Hime 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. Kaguya-Hime regains spent legendary actions at the start of her turn.

Move. Kaguya-Hime moves up to half her speed without provoking opportunity attacks.

Spellcasting. Kaguya-Hime can cast any of her innate spells.

Moon Prism. Kaguya-Hime creates a shimmering, multifaceted magical shield around herself or another creature she can see within 60 ft. of her. The target gains a +2 bonus to AC until the end of Kaguya-Hime's next turn.
