Mephits were extraplanar, outsider creatures similar to imps. They were not native to the material plane as they are somewhat linked to various elemental or quasi-elemental planes of existence. Mephits were roughly humanoid in appearance and somewhat small; approximately 4 feet (1.2 meters) in height. Their disposition depended on their plane of origin, though they were rarely endearing. Each type of mephit had some form of breath weapon, which could usually do minor elemental damage, though it was mostly intended to ward off would-be attackers.
