Sonic Wave

6-level Evocation

You unleash a burst of supersonic energy out in a line 30 feet long and 10 feet wide extending from you. Each creature caught in the area must succeed on a Constitution saving throw. A creature that fails the save takes 6d10 thunder damage. A successful saving throw halves the damage taken.   An invisible creature that fails its saving throw against this spell becomes visible until the end of your next turn. Additionally, all creatures who take damage from this spell are deafened until the end of your next turn.
At higher levels: When you cast this spell using a spell slot of 7th level or higher, the damage dealt increases by 1d10 per spell slot level expended above 6th.
