This spell is a more powerful version of the prevent rot spell. If cast upon a wooden object affected by a wood rot spell, this spell completely cures the wood rot at a rate of 1 cubic foot per round until the object is restored to its original condition. At least part of the original wood must be intact for this spell to cure the rot; an object that has totally rotted into dust cannot be cured.
This spell also cures any rotting, decay, or damage to living trees or plants caused by natural disease or parasites. Damage is cured at a rate of 1 cubic foot of wood per round, or 1 square yard of plant growth per round. At least part of the original plant life must remain intact for the spell to take effect. This spell can cure up to one acre of plant life, so the spell can treat a small grove of diseased trees or a garden plot partly destroyed by insects.
The material components for this spell are mistletoe and a dead woodborer beetle.
Notes: Uncommon for priests from a seafaring culture: otherwise very rare. (Updated from Dragon Magazine.)
