Djinni

If the monster dies outside the Elemental Plane of Air, its body dissolves into dirt, and it gains a new body in days, reviving with all its Hit Points somewhere on the Plane of Air.

The monster has Advantage on saving throws against spells and other magical effects.

The monster has a [[/r 1d100csWish spell. If the monster knows it, the monster can cast it only on behalf of a non-genie creature who communicates a wish in a way the monster can understand. If the monster casts the spell for the creature, the monster suffers none of the spell's stress. Once the monster has cast it three times, the monster can't do so again for 365 days.

The monster makes three attacks, using or in any combination.

The monster casts one of the following spells, requiring no Material components and using Charisma as the spellcasting ability (spell save DC ):
At Will: Detect Evil and Good, Detect Magic
2/Day Each: Create Food and Water (can create wine instead of water), Tongues, Wind Walk
1/Day Each: Creation, Gaseous Form, Invisibility, Major Image, Plane Shift

The monster conjures a whirlwind at a point it can see within 120 feet. The whirlwind fills a -foot-radius, -foot-high centered on that point. The whirlwind lasts until the monster's Concentration on it ends. The monster can move the whirlwind up to 20 feet at the start of each of its turns.
Whenever the whirlwind enters a creature's space or a creature enters the whirlwind, that creature is subjected to the following effect.
Strength Saving Throw: DC (a creature makes this save only once per turn, and the monster is unaffected).
Failure: While in the whirlwind, the target has the Restrained condition and moves with the whirlwind. At the start of each of its turns, the Restrained target takes damage. At the end of each of its turns, the target repeats the save, ending the effect on itself on a success.
