In most respects,
decay is like the spell decompose, except
that it affects living organic matter as well.
Up to 3,000 gp weight in objects or creatures
(300 lbs.) can be affected. Living
creatures who make their saving throw vs.
death magic do not decay, but age 2-12
years as a result of this spell. This spell
also requires the subject to make a system
shock survival roll.
