This spell is an enhancement of the 2nd-level spell flaming sphere. The spell creates one burning globe of fire per level of the wizard. The globes all appear within 30 yards of the wizard and roll in whichever direction the wizard points, at a rate of 100 yards per round. The spheres can roll over any obstacle, even a city wall. Combustible substances are ignited by contact with a sphere. Creatures contacting a sphere must successfully roll a saving throw versus spell or suffer 2d4 HP of damage. Those within five feet of a sphere must also save or suffer 1d4 points of damage. A successful saving throw means no damage is suffered.
The spheres move in the direction the wizard directs, otherwise the spheres will wander aimlessly. Spheres can be extinguished by the same means as any normal fire of their size. The surface of the spheres has a spongy, yielding consistency and does not cause damage except by its flames. It cannot push unwilling creatures aside or batter down large obstacles.
If the spell is unleashed on a large source of easily combustible material (such as a city of at least 50% wooden buildings or a dry forest) there is a 25% chance that a fire storm will start. A fire storm will burn out of control for many days until at least 90% of the combustibles are burned. It will also be so hot that it will melt soft metals and crack thin stone walls.
The material components are a pinch of sulphur, a bit of tallow, a dusting of powdered iron, and a live fire dwelling or fire using creature, such as a fire beetle or fire bat, which must be slain during casting.
