Dancing Flames

You create up to five fist-size lights within range, making them appear as a fireball, dancing flames, or glowing orbs that hover or dance for the duration. Each light sheds Dim Light in a 10-foot radius. As a bonus action you can direct the lights to a point within range and deal 1d6 fire damage. 

You can cast this as a spell to make the lights attack creatures within range. When you cast this spell, you can designate creatures to be unaffected by it. Whenever the Emanation enters a creature’s space and whenever a creature enters the Emanation or ends its turn there, the creature must make a Dexterity saving throw. On a failed save, the creature takes 1d6 fire damage. On a successful save, the creature takes half as much damage. A creature makes this save only once per turn. 

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 1.
