Bites

Melee Weapon Attack: +10 to hit, reach 0 ft., one creature in the swarm's space. Hit: 21 (6d6) piercing damage plus 14 (4d6) fire damage plus 14 (4d6) poison damage, or 10 (3d6) piercing damage plus 7 (2d6) fire damage plus 7 (2d6) poison damage if Ia'Affrat has half of its hit points or fewer. The target must succeed on a DC 16 Constitution saving throw or be poisoned for 1 minute. A poisoned creature repeats the saving throw at the end of each of its turns, ending the effect on itself on a success.

Smoke Jump

Ia'Affrat can travel instantly to a space in sight where there's smoke.

Whirlwind (Recharge 4-6)

Each creature in Ia'Affrat's space must make a DC 18 Strength saving throw. Each creature that fails takes 28 (8d6) bludgeoning damage plus 14 (4d6) fire damage plus 14 (4d6) poison damage and is flung up 20 feet away from Ia'Affrat in a random direction and knocked prone. If the saving throw is successful, the target takes half the bludgeoning damage and isn't flung away or knocked prone. If a thrown target strikes an object, such as a wall or floor, the target takes 3 (1d6) bludgeoning damage for every 10 feet it traveled. If the target collides with another creature, that creature must succeed on a DC 18 Dexterity saving throw or take the same damage and be knocked prone.
