Vrock, considered one of the weakest of demonkind, look like a hideous cross between a vulture and a humanoid. They are no stronger than normal and may be harmed with normal melee and missile weapons. Like all demons they can cause darkness, but only in a 5-ft radius. They also possess the following special abilities which they may use at will: detect invisibility (objects only, otherwise as per the 2nd level magic user spell), gate in another vrock (10% chance of success), or telekinesis (as the 5th level magic user spell, up to 200 lbs).

Vrock are particularly stupid, and cannot normally be bargained with. They love the sight of precious gems and jewellery, however, and also enjoy feasting on the flesh of men.
