This spell accelerates the decay of a ship's hull or deck structure. The wood thus affected crumbles away at a rate of 1-cubic-foot per round, effectively destroying the hull integrity, a mast, or up to 12-square-feet of 1-inch-thick deck each round. All affected wood must be in a continuous area; the rot cannot be sped up in more than one location. The material component is one wood-borer worm

The reverse of this spell is restore wood, which can nullify the effects of a wood rot attack or of natural decay. The material component for the reverse of the spell is a piece of petrified wood.
