Chorus of Destruction

You hum a low tune that spreads out in a 60-foot radius around you. Choose any amount of creatures within that radius that you can see and that can hear you. They must make a Wisdom Saving Throw or suffer 4d6 points of Psychic damage, or half as much on a success. 

For each level of spell slots used to cast this spell beyond 3rd, increase the damage by 1d6.
