You rub the crystal goblet while chanting a poetic verse, and it begins to resonate with an earsplitting tone. Choose a creature within range as your target; the piercing tone wracks the target's body with painful vibrations, and it must make a Constitution saving throw. On a failed save, the creature takes 3d10 thunder damage and has disadvantage on ability checks and saving throws with one ability score of your choice until the end of its next turn. The creature must make a new Constitution saving throw at the end of each of its turns, with the effects described above happening on a failed save. This is repeated every round until the spell ends.
