Thunderclap

0-level (Cantrip) Evocation

Using a Lightning Bug, you create a burst of thunderous sound that can be heard up to 100 feet away. Each creature within range, other than you, must make a Constitution saving throw or take 1d6 thunder damage.
If you warn an ally within range before the explosion, they gain advantage on their saving throw.
At higher levels: The attack's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
