Malicious Elemental Hooligans
Habitat: Planar (Elemental Planes); Treasure: None
Dust mephits are composed of air and fine earth. They are drawn to forsaken places, and they think everything associated with death is hilarious.
Mephits are mean-spirited tricksters that dwell on the Elemental Planes. The six most prominent types of mephits resemble halfling-size gargoyles with wings, exaggerated features, and bodies composed of two elements. Most live self-interested existences, indulging their warped senses of humor or overblown egos on their home planes of existence. Some serve as messengers or spies for genies or magic-users.
Mephits resent leaving the elemental extremes where they make their homes. If loosed on the Material Plane or other realms, they lash out with nasty pranks or by tormenting weaker creatures. When destroyed, mephits explode in a burst of elemental magic.
