A distant cousin of the rot grub, the crystal nipper looks like a tiny eel made of blue crystal. It is instinctively drawn to warm bodies and attempts to burrow into any area of exposed flesh; a victim has the same risk of death as if attacked by a rot grub (death in 1-3 turns unless flame is applied to the wound, causing 1-6 points of damage, or cure disease is cast). The biggest danger from the nipper results from its ability to survive out of the water for short periods of time. At night, nippers sometimes surface and crawl onto the shore, advancing towards any nearby warm bodies (such as sleeping campers) at a movement rate of 1. Because of the nipper’s anesthetizing secretions, sleeping victims may not realize they have been attacked by a nipper until it.s too late. Fortunately, nippers can only survive out of water for an hour, so campers sleeping some distance away from a body of water where nippers are thought to exist are usually safe. Tiny blue worm corpses scattered near the shore of a river or lake is a sure sign of nippers in the area.
