Thunderstruck

A bolt of lightning strikes the ground in a 15 foot radius. Each creature in the area must make a Dexterity saving throw. A creature takes 8d6 lightning damage on a failed save, or half as much damage on a successful one.
The lightning ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.

When the spell is cast the caster must do their best impression of Brian Johnson singing Thunderstruck by AC/DC
