The caster could cause a visible area no larger than a cube 5 feet (1.5 meters) on a side, within a range of 60 feet (18 meters), to burst into flames for up to 1 minute, as long as the caster kept concentrating. Creatures caught in the flames were burned, taking damage that increased as the caster grew more powerful. Any unattended objects in the area were also ignited.
