Create Air

By means of this spell a priest may generate a bubble of fresh, breathable air around a person. This air will drive out the stale air around a person and restore it to the "fresh" state. In cases of individuals adrift in space, this permits another rolling of the die to determine duration of the fresh air. Within a larger envelope of air (such as the deck of a ship or the atmosphere of a planet), the freshened air will drift off, combining with the existing air. This spell can replace air that may be stale or befouled, including air that is poisoned or tainted by a cloudkill or stinking cloud spell. Creating additional air around a single individual does not create a larger envelope; The caster can refresh the air within his own personal air envelope and that of others within the range of the spell, without needing to touch those individuals. The reverse of this spell destroy air, immediately reduces the air around one target to "fouled", with all effects of that change. If the create air spell is used within a gravity field, inside otherwise hostile surroundings (such as inside a cloudkill or stinking cloud), it will allow the recipient a single clean breathe before the created air bubbles to the surface.
