A chestnut unicorn with ember-red eyes that haunts mines and volcanic tunnels, hurling fire from its horn at anyone who intrudes on its underground realm.
Sometimes called a pyrocorn, this unicorn has a chestnut coat and eyes that glow red like forge coals.
Once per day each, at 11th level, it can cast fireball, produce fire, produce flame, pyrotechnics, heat metal and burning hands, most of them launched from its horn. Flame, smoke and heat of any kind, natural or magical, never harm it. It attacks trespassers ferociously but will not follow them into the deep places.
Bay unicorns lair in caves, mines, labyrinths, dungeons and lava tubes no more than a few hundred feet down, scratching territorial marks into the rock. A ranger who finds such a sign underground may be startled, and more so to learn its maker is evil and eats meat as well as fungus. Pairs meet once a year to mate, and a mother guards her foal for six months before abandoning it. Only a deeply evil woman devoted to fire magic or a fire god may ride one.
It eats fungi and small cave creatures. Its horn goes into potions of fire breath.
