Chaosball

A bright streak flashes from you to a point you choose within range and then blossoms with a low roar into an explosion of some kind. Each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 6d6 damage on a failed save or half as much damage on a successful one.

Choose one of the d8s. The number rolled on that die determines the damage type, as shown below.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
