This spell creates a sphere of fresh air around the individual or object touched by the caster. Gaseous and vaporous attacks are unable to penetrate this airsphere, and acids or other liquids simply wash over it. The spell generates oxygen, enabling you to breathe underwater or in other areas with no fresh air (though as the sphere surrounds its recipient or object, it hampers movement in or under water).

This spell doesn’t protect against natural or magical effects occurring within the airsphere: for example, if a vial of acid is thrown into the sphere, it enters; if it breaks, its contents splash for their normal effects. This spell was specially crafted to guard against dragon breath; it will absorb and negate any breath weapon upon contact but is itself destroyed, instantly and harmlessly, in doing so.
