Thunderclap

You create a burst of thunderous sound, which
can be heard 100 feet away. Each creature
other than you within 5 feet of you must make
a Constitution saving throw. On a failed save,
the creature takes 1d6 thunder damage.
At higher level
Damage increases by 1d6 when you reach
5th level (2d6), 11th level (3d6), and
17th level (4d6).
