Cold Flare

As you hold out your hands with your palms facing away from you. Each creature in a 30-foot cone must make a Constitution saving throw. A creature takes 4d6 cold and 4d6 fire damage and have their movement halved on a failed save, 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 5th level or higher, the damage increases by 1d6 for each slot level above 1st.
