Unwary creatures who trod upon the moss fall into the mass of it, where they will be devoured. The bog moss' digestive juices inflict 10 points of damage per round until the victim dies and is ingested. The bog moss' body is more unstable than quicksand; creatures which fall into its body cannot gain purchase to climb out. It is difficult to rescue a trapped creature, as the bog moss' digestive juices also consume organic matter, including ropes and wooden poles. Only chains, metal cables, and magic might be employed successfully.
