Ice devils resemble upright remorhaz with humanoid arms and legs, and knotted, barbed tails. They dominate the 8th plane of Hell, which serves as their frozen home. They are also very strong (18.76 strength) and enjoy torturing their victims before killing them. Ice devils also have secret personal names which can be used to summon them, if the name is somehow known to the conjurer.

In combat, these devils will usually rely on their claws, mandibles, and tails. Occasionally (25%), they wield long, magical spears which they can use to impale and freeze their victims (2d6 damage plus the victim must save vs paralysation or be reduced to half their normal move).
