DESCRIPTION

This spell creates a 10-foot-diameter pocket of pure, fresh air. The pocket has a semipermeable surface; it allows persons to enter and leave its area, but water, vapors, gasses, etc. cannot enter the sphere. Physical objects such as arrows or thrown weapons may pass into the sphere.

Strong winds (over 25 mph) disrupt this spell as if a dispel magic had been cast at the sphere. Pressure from being deep underwater does not affect the sphere.

The air remains pure and clean for the duration of the spell. Up to five Medium creatures may be contained in the sphere at one time.
