Malicious Elemental Hooligans
Habitat: Planar (Elemental Planes); Treasure: None
These mephits embody the merging of earth and fire as glowing magma. They love melting things, but they loathe magmins and attack them on sight.
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.
