Arcane Artillery

Motes of fire streak from your hand to three different points you can see within range and explode. Each creature in a 10-foot-radius Sphere centered on each of those points makes a Dexterity saving throw. A creature takes 4d6 Fire damage on a failed save or half as much damage on a successful one. A creature in the area of more than one explosion is affected only once.

A nonmagical object that isn’t being worn or carried also takes the damage if it’s in the spell’s area, and the object starts burning if it’s flammable.

When using a higher level spell slot: When you cast this spell using a spell slot of 5th level or higher, you create an additional mote of fire for each slot level above 4.
