This spell can be used to duplicate the disintegration spell with the added effect of making only selected parts disintegrate - if they fail their saving throw. The selected parts can be as specific or as general as the caster desires, but it takes additional casting time to select the specified parts. For every ten words (don't count a and the as words) in the specification an additional modifier is added to the casting time until a casting time of ten is reached (at twenty words). This is changed into a one round casting time, unless even that is not enough to specify all different parts. If the objects to be disintegrated are carried by a person that person gets a saving throw first. If he fails, then the items get a saving throw versus disintegration. If the specified objects fail, they are gone completely.
Note that this spell has a duration. This duration is the time during which the specified objects (or creatures) can be disintegrated if they enter the cubic area of effect. They have to make a saving throw for every round they are in this area. Thus, this spell could be placed on a doorway to disintegrate all living things passing through that don't display a certain sign. If the specification can be circumvented then nothing happens. The duration does not include those items or creatures affected by the spell: once they are disintegrated they stay disintegrated.
