The Grand Finale

A shimmering bright light along with loud cheerful music sound emerges from the caster as they preform.

Targets within range must make a charisma saving throw. Targets take 4d6 psychic damage and get disadvantage on their next attack or half as much damage on a successful save.

Allies in the cone range instead regain hit points equal to half of that amount. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
