By use of this spell, a druid can make one creature immune to wind or any form of precipitation. In essence, a shell is created around the creature that no form of precipitation (including rain, sleet, snow, fog, hail, meteorites, or any other natural objects falling from the sky) can pass through. The shell also reduces the speed of any wind touching the protected creature by 10 MPH per level of the druid. Any form of magical wind or precipitation is unaffected by this spell, but spells that summon up a natural wind or storm are affected. Any air elemental attacking a protected creature receive a -7 on all attack rolls, and the protected creature gets +5 on all saving throws against magical precipitation that inflicts damage, as well as against air elementals.
This spell in no way protects against lightning or temperature extremes.
The material component is a fan-shaped leaf, which is crushed in the casting, and a diamond of 500 gp or greater value, which is destroyed in the casting.
