Range:  0
Components:  V, S
Duration:  1 hour per level
Casting Time:  4
Area of Effect:  20-foot cube
Saving Throw:  None

This spell creates an area of pure, clean air in the location the caster desires. The air pocket appears in a 20-foot cube and remains stationary in the location it was cast. It cannot be made to move with the caster. The cube is self contained, and will keep out surrounding air or water. This makes it a useful spell to cast underwater, in wildspace, or around poisonous gas. The cube will only keep out liquids, gases, and outside air. Humanoids, creatures, and objects can pass through freely. The air in the cube will remain fresh for the duration of the spell.
