This spell may target a single, solid object, regardless of composition, that weighs up to 15 pounds, and causes it to be instantly eaten by decay. Swords will rust and break apart, food will rot and stink, small trees will become lifeless rotting shafts of wood, and stones will crumble into dirt. Magical and psionic items gain a +4 bonus to their save to resist the effect, but are otherwise vulnerable.
If a creature is targeted, the spell deals 4d4 damage (half that on a successful Fortitude save). If this damage is enough to bring the target to -10 hit points or fewer, the creature's body is instantly eaten by decay, becoming a rotten, smelly pile of muck and bones.
Material component: A chunk of rotten wood.
