Debilitating Breath (charges)

You exhale a pulse of high-pitched, nearly inaudible sound in a 60 foot line. Each creature in that area must make a Constitution saving throw. On a failed save, the creature takes 10d6 thunder damage and is incapacitated until the end of its next turn. On a successful save, the creature takes half as much damage and isn't incapacitated.You can use this ability the number of times equal to your proficiency bonus, short rest to reset. Damage dealt by this breath weapon is treated as siege damage.
