The Corporeal Beast, often simply referred to as "Corp", is a large monster residing in its cave, accessible via a games necklace or through an entrance in level 21 Wilderness east of the Graveyard of Shadows. It has a very large health pool of 2,000 Hitpoints, coupled with high Defence and 50% damage reduction to any non-spear weapons. If all players leave the room, it regenerates its health to full.
