Texashtic's Miniaturized Fireball

You hurl a small molten ball of fire. Choose a creature or object you can see within range plus up to one additional creature or object within 5ft of the original target. Targets must succeed on a Dexterity saving throw or take 1d8 fire damage. Objects automatically fail this save. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 1d8 and can hit up to one additional target (adjacent to the original target) when you reach 5th level (2d8 and up to 2 adjacent targets), 11th level (3d8 and up to 3 adjacent targets), and 17th level (4d8 and up to 4 adjacent targets).
