Ball of Fire

A bright streak flashes from your pointing finger to a point you choose within range which grows into a burning ball as it blossoms with a low roar into an explosion of flame. Each creature in a 5-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 2d8 fire damage on a failed save, or half as much damage on a successful one.

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