Nornis' Windwall

A spell which creates an immobile wall of air (or any other gas present) with a strong suction on one side and a strong pressure on the other. The pressure side is strong enough to bar a man or animal from passing through, but not an object with a high ratio of speed to cross-section (e.g., a thrown spear), although it does lose speed (GM discretion). The pressure side is elastic, and if horizontally oriented forms a comfortable sleeping surface or landing pad, provided one spreads out before falling on it. The wall must be "anchored" to the ground or similar strong surface. The wall dissipates immediately after Duration or if the caster passes from line-of-sight or falls unconscious.

A windwall is one foot thick and SIx2 square yards or less in area. With the basic spell, it must be flat. It is invisible, but the wind can be heard nearby. The pressure-side has no friction, so it is very difficult to maintain balance when trying to walk on a horizontal wall; test against Agility. Walking through a vertical wall from the suction side will likely cause a fall; test versus Agilityx2.
