Burning Singularity

A flaming, 3-inch wide bead seeks out a target of your choosing within range. Target must make a Dexterity saving throw. A creature takes 5d6 fire damage and 1d6 force damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the fire damage or the force damage (your choice) increases by 1d6 for each slot level above 4th.
