Pyrotechnics {Priest}

A pyrotechnics spell draws on an existing fire source to produce either of two effects, at the option of the caster.
First, it can produce a flashing and fiery burst of glowing, colored aerial fireworks that lasts one round. This effect temporarily blinds those creatures in, under, or within 120 feet of the area that also have an unobstructed line of sight to the effect, for 1d4 +1 rounds unless the creatures roll successful saving throws vs. spell. The fireworks fill a volume ten times greater than the original fire source.
Second, it can cause a thick, writhing stream of smoke to arise from the source and form a choking cloud that lasts for one round per experience level of the caster. This covers a roughly hemispherical volume from the ground or floor up (or conforming to the shape of a confined area) that totally obscures vision beyond two feet. The smoke fills a volume 100 times that of the fire source.
The spell uses one fire source within the area of effect, which is immediately extinguished. An extremely large fire can be used as the source, and it is only partially extinguished by the casting. Magical fires are not extinguished, although a fire-based creature (such as a fire elemental) used as a source suffers 1d4 points of damage, plus 1 point of damage per caster level. This spell does not function under water.
