Create Smoke (Reversible)

By igniting even a tiny spark of flame, the priest creates a dense plume of smoke that obscures vision in 90-foot radius and makes breathing in the area difficult. Any air-breathing creature within the cloud must make a saving throw vs. death magic. Failure means the creature can only retreat from the cloud, coughing and rubbing its eyes. Such creatures have a -4 penalty to their attack rolls for 4 rounds after they leave the cloud. Those who make their saving throws can remain in the cloud, but fight at a -4 penalty while there. Those who make the saving throw and leave the cloud suffer no further ill effects. The smoke cloud lasts for 4 rounds and then dissipates. Strong winds will reduce the duration by half and gale force winds dissipate the smoke immediately.

The reverse of the spell, dissipate smoke, clears smoke from the area for the duration of the spell. It affects only smoke, not mists, fog, vapors, or other visible gases.
