Pyrotechnics turns a fire into a burst of blinding fireworks or a thick cloud of choking smoke, depending on your choice. The spell uses one fire source, which is immediately extinguished. A fire so large that it exceeds a 20-foot cube is only partly extinguished. Magical fires are not extinguished, although a fire-based creature used as a source takes 1 point of damage per caster level.
Fireworks: The fireworks are a flashing, fiery, momentary burst of glowing, coloured aerial lights. This effect causes creatures within 120 feet of the fire source to become blinded for 1d4+1 rounds (Will negates). These creatures must have line of sight to the fire to be affected. Spell resistance can prevent blindness.
Smoke Cloud: A stream of smoke billows out from the fire, forming a choking cloud that spreads 20 feet in all directions and lasts for 1 round per caster level. All sight, even darkvision, is ineffective in or through the cloud. All within the cloud take -4 penalties to Strength and Dexterity (Fortitude negates). These effects last for 1d4+1 rounds after the cloud dissipates or after the creature leaves the area of the cloud. Spell resistance does not apply.

Target: one fire source, up to a 20-ft. cube
