Tiny Fireball v.2

A small ball of flame forms in the palm of your hand and is thrown like a ball. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 3d6 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 being worn or carried.

There usually isn't a point to use this at higher levels as it's typically replaced by the normal fireball spell at level 5.
