Crossfire Hurricane

A symbol made of fire shoots out toward a target. Make a ranged spell attack against the target. On a hit, the target takes 3d4 bludgeoning damage. Hit or miss, the symbol then explodes. Each creature within 10 feet of the target must make a Dexterity saving throw or take 3d4 fire damage, or half on a success. When you cast this spell, you can instead choose to split the symbol into three different pieces, increasing by one per spell level above 2nd. You can direct the symbols to targets just as before, and they each deal 1d4 damage on the attack and explosion. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage (both initial and later) increases by 1d4 for each slot level above 2nd.
