--- Flaming Brand (Su) The hide of every devil's longhorn is marked by a smouldering rune that marks it as the property of a given devil. As the result, the devil's longhorn sheds light as if it were a torch and deals 1d6 fire damage per round to any creature riding it. When the devil's longhorn dies, its rune is extinguished and the devil the owns it immediately realizes that the longhorn has died. Thundering Hooves (Su) The hooves of a devil's longhorn have the thundering weapon property. Whenever a devil's longhorn scores a critical hit with a hoof, the target takes 1d8 points of sonic damage and must make DC 14 Fortitude save or be permanently deafened.
Devil's longhorns are to ordinary cattle what hell hounds are to ordinary dogs. Though they remain violent and willful, these fiendish longhorns have all been domesticated, at least in the technical sense of the word. Devil's longhorns are only found in herds or on properties maintained by various devils. These herds provide devils with beasts of burden, foodstuffs, and an excuse to press lesser fiends into service as brutally-overworked cowhands.
