Special Traits

  • Death Burst. When the mephit dies, it explodes in a flare of lightning in a 15-foot radius. Creatures in the area must make a DC 12 Dexterity saving throw, taking 9 (2d8) lightning damage on a successful saving throw, or half as much damage on a failed one.
  • Innate Spellcasting. The mephit’s spellcasting ability is Charisma (spell save DC 12, +4 to hit with spell attacks). It can innately cast shocking grasp at will requiring no material components.


  • Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage plus 2 (1d4) lightning damage.
  • Lightning Breath (Recharge 6). The mephit exhales lightning in a 15- foot line that is 1-foot wide. All creatures within that area must make a DC 12 Dexterity saving throw, taking 9 (2d8) lightning damage on a failed save, or half as much damage on a successful one.


This small creature appears to be a humanoid-shaped being composed of electricity. Bluish-white lighting arcs in small bursts from its body.

Lightning mephits come from the Elemental Plane of Air and Elemental Plane of Lighting. Rarely are they encountered elsewhere unless summoned or called by a spellcaster. If encountered on the 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 the 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).

A lightning mephit’s natural weapons are treated as magic weapons for the purpose of overcoming damage reduction.
