Discordant Melody

When you cast the spell, choose a point you can see. A wave of sound shoots from the string to that point. Each creature within 5 feet of that point makes a Dexterity saving throw, taking 3d10 Thunder damage on a failed save or half as much damage on a successful one.

Until the spell ends, you can take a Magic action to send a sound wave in that way again, targeting the same point or a different one.

The spell ends completely if the user is silenced.

Using a Higher-Level Spell Slot. The damage increases by 1d10 for each spell slot level above 3.
