Wind wall
From Ardrana
The wind wall spell brings forth an invisible vertical curtain of wind 2 feet thick and of considerable strength -- a strong breeze sufficient to blow away any bird smaller than an eagle or tear papers and like materials from unsuspecting hands. Normal insects cannot pass such a barrier. Loose materials, even cloth garments, fly upward when caught in a wind wall. Arrows and bolts are deflected upward and miss, while sling stones and other missiles under two pounds in weight are more likely to miss their targets. Gases, most breath weapons, and creatures in gaseous form cannot pass this wall, although it is no barrier to noncorporeal creatures.
Note: This version of armor originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
