You summon a ball of intense flame and heat and throw it at a target. If there is a creature in the way of Cruel Sun, it must make a DC 20 + your Cha modifier Strength save or be pushed back to the intended point of contact and suffer an extra 4d12 fire damage along with the following: Each creature in a 30-foot-radius sphere centered on a point designated by the caster must make a Dexterity saving throw. A target takes 18d12 fire damage on a failed save, or half as much damage on a successful one.
The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.
The caster can determine how large the sphere shall explode below a 30-foot-radius sphere, instead, having the ability to decide if the sphere is less than or equal to 30 feet in increments of 5.
