15-foot cone of lightning, damage 1d8 electricity, Reflex DC 13 half. The save DC is Constitution-based and includes a +1 racial bonus. Creatures wearing metal armor take an extra +2 points of damage from a lightning mephit’s breath weapon.
A lightning mephit takes 1d4 points of damage per gallon of water it contacts. Pouring water onto a lightning mephit requires a successful ranged touch attack. Water from other sources, such as spells or effects that create water but do not specify an amount in gallons, deal 1d4 points of damage per caster level to a lightning mephit within its area of effect. Damage from water-based attacks, like the slam attack of a water elemental, is increased by 50% against a lightning mephit.
Environment any (Elemental Planes of Air or Quasi-Elemental Planes of Lightning)
Organization solitary, gang (2-4 mephits of mixed types), or mob (5-12 mephits of mixed types)
Lightning mephits come from the Elemental Planes of Air and Quasi-Elemental Planes of Lighting. Rarely are they encountered elsewhere unless summoned or called by a spellcaster. If encountered on a material plane it is usually in the employ of some spellcaster who has called it to do his or her bidding. Occasionally however, a lightning mephit stumbles into a material plane by way of a lightning storm (when said storm reaches into the Plane of Air and opens a temporary portal). Lightning mephits found anywhere except their home plane will be encountered in areas where lightning and storms are most prevalent. A lightning mephit is about 4 feet tall and weighs about 1 pound.
A lightning mephit begins combat with a lightning bolt attack, targeting the opponent closest to it. On the following round it breathes a cone of lightning on its foes if most are within range; otherwise it moves to melee combat. Once in melee, a lightning mephit uses its natural attacks and shocking grasp, as well as its breath weapon (if it can catch most of its opponents in the cone).
