We discovered early on that not every creature could get its own entry. We not only saved space by combining similar creatures into large entries, we also made the book easier to read and use by not endlessly repeating material between entries.
Genies are humanlike beings who dwell on the elemental planes.
They are famous for their strength, guile, and skill with illusion magic. Combat Genies prefer to outmaneuver and outthink their foes. They are not too proud to flee if it means they'll live to fight another day. If trapped, they bargain, offering treasure or favors in return for their lives and freedom. A genie can enter any of the elemental planes, the Astral Plane, or the Material Plane.
