Claw. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 21 (3d10 + 7) slashing damage. If the creature is a fiend or celestial, it takes an extra 14 (4d6) force damage.

Wings. Andirivithine beats her wings. Each creature within 20 feet of Andirivithine must make a DC 20 Strength saving throw, or take 16 (3d10) bludgeoning damage and be knocked prone. On a success, a creature takes half as much damage and is not knocked prone. If a creature is within 10 feet of Andirivithine, they make this save at disadvantage and, pass or fail, are pushed back 10 feet.

Rain of Roses (1/Day). Andirivithine causes a flurry of roses within a 120-foot radius centered on her. If she is outside of her city, the radius shrinks to 10 feet. The area becomes lightly obscured for 1 minute, and she chooses either Abjure or Smite, causing one of the following effects to occur in the area for 1 minute as the petals fall:

• Abjure. The area is difficult terrain for all creatures other than Andirivithine. A celestial or fiend cannot willingly enter the radius. When a creature enters the area for the first time or ends its turn in the area, they must make a DC 15 Wisdom saving throw or be affected as if by scatter. If a creature succeeds this save, they make following saves against Abjure with advantage.
• Smite. Any fiend, celestial, and/or creature of Andirivithine's choice that enters the area on their turn or ends their turn in the area must make a DC 15 Dexterity saving throw or take 2d10 force damage, taking half as much damage on a success. If a creature succeeds this save, they make following saves against Smite with advantage.

Sprout Roses (1/Day). Andirivithine causes roses to sprout in six places within 120 feet of her, each growth with a diameter of 5 feet. Celestials and fiends cannot willingly come within 5 feet of these spaces, and they are difficult terrain for all creatures other than Andirivithine. If she uses this effect outside of her city, she can use Rain of Roses with its normal radius if she has not already expended the use.

Supreme Banishment. Andirivithine chooses any number of creatures within 120 feet of her. They must make a DC 23 Wisdom saving throw or be teleported outside the boundary of the city, or to a location of her choice within the city, which can include an altitude of up to 120 feet directly above the space where they were previously standing. If a creature is a celestial or fiend or is within 10 feet of a rose, they make this saving throw with disadvantage. She can also choose one creature to make the saving throw with disadvantage, or choose another creature who is outside of her range but within the city and cause them to make the saving throw as well. On a success, a creature is pushed 10 feet away from her and must make a DC 20 Strength saving throw or fall prone. If a creature fails this saving throw, they are immune to the effect of Supreme Banishment for 1 minute. Andirivithine cannot use this effect when she is outside the bounds of her city.

Andirivithine 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. Andirivithine regains spent legendary actions at the start of her turn.
