Hogwarts schooling

A tiny ball of fire flashes from your wand to a point you choose within range and then explodes into a fiery blast on impact. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one. The fire spreads around corners. It ignites flammable objects in the area that aren’t worn or carried.
