Teleporting Fireball

An explosion of fire surrounds you, enveloping your exlscape to somewhere else. Each creature in a 10-foot-radius Sphere centered on you makes a Dexterity saving throw, taking 8d6 Fire damage on a failed save or half as much damage on a successful one, excluding yourself. You then teleport to a spot within 40 ft.

Flammable objects in the area that aren’t being worn or carried start burning.

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