Causes a light rain to fall in the area of effect. One millimetre of rain will fall every 8 rounds.
- After 2 rounds, small candles will be extinguished.
- After 3 rounds, fat candles will be extinguished.
- After 4 rounds, thin light material will become damp and thoroughly wet thereafter. Flat non-porous surfaces will become wet.
- After 8 rounds, twigs and heavy material—such as canvas—will become damp and thoroughly wet thereafter. Semi-porous surfaces, like bare wood, will become damp.
- After 12 rounds, flat non-porous surfaces will become filmed with water.
- After 16 rounds, torches will be put out. Water will begin to run off smooth surfaces in rivulets.
- After 20 rounds, semi-porous surfaces will become thoroughly wet to the touch. Earth will become spongy to the touch.
- After 28 rounds, small fires will slow and become smoky.
- After 40 rounds, rivulets will run upon sloped earth. Small fires will be put out.
- After 60 rounds, large fires will slow and become smoky.
- After 90 rounds, the flames of large fires will be put out, though the coals themselves will continue to smoulder.
If the temperature is balmy or hotter, the duration of the spell will be doubled in areas of thick vegetation. The spell is always halved in arid environments devoid of grass and thick vegetation.
In chilly weather, the precipitation will fall as sleet. In colder conditions (frosty and below), precipitation will fall as snow — in which case the duration of the spell is doubled, but the effects are halved (or diminished until the snow is allowed to melt).
If precipitation is combined with a sustained fire-based spell, such as a wall of fire, a fog which is double the area of effect will be formed. If combined with a sustained cold-based spell, such as an ice storm, then a blizzard twice the ordinary strength of the spell effect will be formed, and the amount of snowy precipitation doubled.
