It is otherwise similar to the spell of the same name. Jann are formed out of all four elements and must therefore spend most of their time on the Material Plane. They favor forlorn deserts and hidden oases, where they have both privacy and safety. Jann society is very open, treating males and females as equals. Each tribe is ruled by a sheik and one or two viziers.
Many jann bands are nomadic, traveling with herds of camels, goats, or sheep from oasis to oasis.
These itinerant jann appear human in every respect and are often mistaken for them, unless they are attacked. The territory of a jann tribe can extend hundreds of miles in any direction. Jann speak Common, plus Auran, Aquan, Ignan, or Terran, plus Celestial, Abyssal, or Infernal. Combat Jann are physically strong and courageous, and do not take kindly to insult or injury. If they meet a foe they cannot defeat in a stand-up fight, they use flight and invisibility to regroup and maneuver to a more advantageous position.
