====== Magic Device ======

To determine the caster level power of a magic device when it is unlisted, use the minimum level required to cast the powers contained within the device. For example, the //rod of passage// can produce //teleport without error// and astral travel. //Teleport without error// is a magic-user spell, so we can figure that the //astral spell// power involved would be the 9th level magic-user variety and not the 7th level cleric variety. Therefore, since an 18th level magic user is required to cast a 9th level spell, we cna assume the //rod of passage// operates at the 18th level of power.
