D&Dtools1

A driving rain falls around you.
It falls in a fixed area once created.
The storm reduces hearing and visibility, resulting in a -4 penalty on Listen, Spot, and Search checks.
It also applies a -4 penalty on all ranged attacks made into, out of, or through the storm.
Finally, it automatically extinguishes any unprotected flames and has a 50% chance to extinguish protected flames (such as those of lanterns).
The rain damages good creatures, dealing 2d6 points of damage per round (good outsiders take double damage).
In addition, each round, a blast of fire strikes a randomly selected good outsider within the spell's area, dealing 5d6 points of fire damage.
After the spell's duration expires, the water disappears.
Material Component: A flask of unholy water.
