Warding wind

Warding wind was an evocation spell that created a loud cyclone of protective wind around the caster.

Effects
The spell stirred the air within a radius of 10 feet (3 meters) of the caster to spin in a violent wind at a speed of 20 miles per hour (32 kilometers per hour) that lasted for up to 10 minutes, as long as the caster kept concentrating. The wind was loud enough to render all verbal communication impossible within the affected area. It extinguished unprotected flames in the area and also dissipated vapors, gases, and fog. Any creature other than the caster could only traverse the area at great difficulty, and projectile weapons crossing the wind became extremely unreliable.

Components
The spell only required verbal components.
