Erupting Flames

Flames erupt from the caster, creating a violent burst of fiery energy. Each creature in a 20-foot radius centered on the caster must make a Dexterity saving throw, taking 6d6 fire damage on a failed save, or half as much damage on a successful one. Additionally, the area becomes difficult terrain for 1 minute as the ground heats up, causing it to crack and smolder.

For each level above 3rd that this spell is cast it does an additional 1d6 fire damage and its range increases by 5ft.
