Arcane Firework

You create three sparkling bolts of flame and hurl them at three points within range. Each bolt will create a colorful and fiery explosion with a 5-foot radius originating on the points you choose. Each creature in the area must make a Dexterity saving throw. It takes 3d12 fire damage on a failed save, or half as much on a successful one. A creature can take this damage no more than once.

If two or more explosions affect a creature, it makes the saving throw with disadvantage.

The explosions spread around corners. It ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, you create one additional bolt for each slot level above 3rd.
