Create Air

You create volume of breathable air within a 30 foot radius sphere centered on the target point chosen by the caster. This air be used to fill a sealed container or disperse gases, but cannot be formed inside of a living creature. Attempting to create the air within a volume too small to contain it will result in the spell creating enough air to fill the available space and no further. At its full volume, this provides up to 8 hours of air.
