You choose a point within range and fill a 20-foot-radius sphere centered on it with overwhelming insect chittering. Each non-deafened creature in the area must make a Wisdom saving throw.
On a failed save, a creature takes 2d8 thunder damage, is deafened until the end of its next turn, and subtracts 1d6 from the next attack roll or ability check it makes before then. On a successful save, the creature takes half as much damage.
