Cremation

As you hold your hands with thumbs touching and fingers spread, a thick current of blue flames sprouts from your palm. Each creature in a 20-foot cone must make a Dexterity saving throw. A creature takes 4d8 fire damage on a failed save, or half as much damage on a successful one.

Turn any flammable objects in the area that aren't being worn or carried to ash.

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