* There are two types of Flying characters.
   * The Wizard or a character using the ability of the Scroll of Flight -- magical flight.
   * Angels, the Bat, the Lightning Elemental use natural flight.

* Flying characters cannot move over the walls, columns, brambles of the Druid, rubble of the Illusionist, and webs of Araknis.

* Flying characters can fly over squares occupied by enemy characters.
