Horned devils are inhabitants of the 6th and 7th planes of Hell. Although considered to be greater devils, they are weaker than either ice devils or pit fiends, whom they despise. Horned devils have their own personal names which can be used to summon and control them.

In combat, horned devils typically use either a barbed fork (75%, 2d6 damage) or a jagged whip (25%, 1d4 damage plus the victim is stunned 1d4 rounds—save vs spells for unlisted categories to avoid). If unarmed, these devils can attack with their sharp claws or a bite. Finally, they also can attack with their sharply-tipped tails which cause weeping wounds (1d3 damage plus 1 hp of damage per turn until the wound is bound or cured).
