In the Dungeons & Dragons fantasy role-playing game, the boneclaw is an undead. They resemble humanoids who are half skeletal and half without skin, with their sinew and muscle exposed. The most prominent feature of the boneclaw are its claws; its three, bony fingernails seem to grow and shrink randomly between two to ten feet long, and are razor sharp. There is no single known origin of boneclaws; some say they are necromancers who have been mutated by their own experiments while others say they hail from another world.
