Multiattack

The wind's harp devil makes two infernal noise attacks.

Infernal Noise

Ranged Spell Attack: +6 to hit, range 60 ft., one target. Hit: 9 (2d8) psychic damage plus 3 (1d6) thunder damage.

Hellish Chorus (Recharge 5-6)

The wind's harp devil creates an infernal cacophony. Each creature within 30 feet of it must make a DC 14 Dexterity saving throw, taking 13 (3d8) psychic damage and 7 (2d6) thunder damage on a failed save, or half as much damage on a successful one. Devils are immune to the hellish chorus.
