Arcane Flair

Cast out a small mote of compressed fire to a point you can see within range, as it bursts into a 15ft cube of fire. Each creature within the 15ft cube must make a Dexterity saving throw. On a failed save, the creature takes 2d8 fire damage, or half as much damage on a successful one.

The fire ignites any flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
