This spell brings forth an invisible curtain of wind of considerable strength — sufficient to blow birds as large as crows upward, or to tear papers and like materials from unsuspecting hands. (If in doubt, a saving throw versus spell determines whether the subject maintains its grasp.) Normal insects cannot pass such a bar- rier. Loose material, even cloth garments, caught in a wind wail will fly upward. The material components are a tiny fan and a feather of exotic origin.
