Air Embodiment

Air Form. The elemental can enter a hostile creature's space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.

Arial Stealth. If the elemental hides while flying and in air, it has advantage on the Dexterity (Stealth) check.

Storm Aura. Any creature that hits the elemental with an attack while within 10 feet of it takes 9 (2d8) lightning damage, as does any creature that starts its turn there.

Multiattack. The elemental makes two slam attacks.

Slam. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 22 (4d6 + 8) bludgeoning damage.

Thunderous Column. Ranged Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 16 (3d10) lightning damage, plus 16 (3d10) thunder damage.

Whirlwind (Recharge 4–6). Each creature in the elemental's space must make a DC 13 Strength saving throw. On a failure, a target takes 26 (4d8 + 8) bludgeoning damage and is flung up 20 feet away from the elemental in a random direction and knocked prone. If a thrown target strikes an object, such as a wall or floor, the target takes 5 (1d10) bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 22 Dexterity saving throw or take the same damage and be knocked prone.

If the saving throw is successful, the target takes half the bludgeoning damage and isn't flung away or knocked prone.
