Bogyn's Nastiness Rating: 43 (Horrifically Nasty)
Creature Families: Mutant, Insectoid, Goop
A variety of giant scavenger slugs that digest their food via the acidic juices that leak out of their skin, then sucking them up through their mouths. They generally only feed on the already dead (and in some cases, the undead). If a Corpsesucker is cut in twain, there is a chance that both pieces will regrow into different Corpsesuckers. They stick to walls easily and generally live in the depths of dangerous dungeons, barrows, and temples where they feed on the leftover parts of adventurers killed and partially devoured by other monsters or traps.
