School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Duration: Preserve: (1 + spell slot level used) months / caster level up to 10 years ; Decay:1 month / level

Preserve:
By the use of the Preserve spell, the caster can halt the decay (including shelf ripening) of any nonliving matter. In the case of food or drink, the substance must first be placed in a closed container of some kind. Preserve is dispelled when the container is unsealed. For other material, the spell runs its full duration unless dispelled by some other means. If the target is a corpse, it must be packaged completely in a container (sack, trunk, etc), and a spell slot of 2nd level or higher must be used.

The material component required is a small vial of salt sealed with wax.

Decay:
The reverse of this spell, Decay, causes immediate decay equal to one month per caster level.

The material component required is a pinch of dung or mold.

Based on 2e AD&D spell Preserve, from the Chronomancer suppliment (TSR 9506).
