Storm Magic, also referred to as Chaos magic, is a branch of Elemental Magic that specializes in summoning weather disasters. It is not good magic and magicians do not use it, unless following the path of a Chaos god, such as Set or Apophis. With Storm Magic, magicians are able to use extreme winds, lightning, tornadoes, cyclones, hurricanes, etc. Storm Magic also enables the user to summon deserts and sand-based disasters as Egypt experiences many of these. Storm Magic and Combat Magic can also be employed simultaneously, an example being Amos Kane with the Set avatar.
During the attack on the First Nome, various rebel magicians used storm magic.
