Protection From Nonmagical Gas

2nd-level abjuration

Casting Time:1 action
Range:Self
Components:V, S, M (a silk fan and a 2-inch square of thick gauze)
Duration:1 hour

A 20-foot-radius sphere centered on you provides total protection from all nonmagical gases and mists. When they come into contact with the sphere, they dissipate instantly, leaving nothing but pure clean air. If air is outside the sphere, the sphere is filled with pure clean air for the duration of the effect. This spell does not work in a vacuum or underwater. The spell ends if the sphere comes in contact with a magical gas.
