Chorus of the Lost

You summon the eerie song and wailing of lost souls from a point you can see within range. Each creature in a 15-foot-radius Sphere centered there must make a Wisdom saving throw. On a failed save, the target takes 2d6 Psychic damage, and it has the Frightened condition for the duration. On a successful save, it takes half as much damage, and it has the Frightened condition until the end of its next turn. A Frightened target repeats the save at the end of each of its turns, ending the spell on itself on a success.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 2.
