Fireball (V, S, M)

Each creature in a 20-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 arent
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.
