Through this spell, a priest can slow the effects of aging on any nonliving item. The item must be sealed in an airtight container. It is the air that is enchanted, not the item within. A skilled artisan must construct a container with a volume up to 15 cubic feet; it costs at least 1,000 gp. During the preparation time, the priest must spend six hours per day enchanting the container and drawing sigils and runes on its inner surfaces. The enchantment makes the container airtight against natural decay, though tampering ends the spell. Once items are placed inside the container and the spell is cast, time effectively stops inside. The items do not age or decay in any way. If the container is broken, the items are unharmed and resume aging at the normal rate.
When casting, the priest can also place a cause blindness, cause deafness, cause disease, or bestow curse spell on the container. Tampering with the container unleashes the spell on the tampering individual(s). Once the container is broken and the air of permanence lost, this additional spell is lost, as well.
The material component for this spell is a bottle of air taken from the remains of the lungs of a creature that has been dead at least 100 years.
Notes: Granted to air elementals.
