  • Death Burst. When a mineral mephit dies, it explodes in a burst of jagged stone and crystals. Each creature within 5 feet of it must make a DC 11 Dexterity saving throw, taking 5 (2d4) slashing damage and 2 (1d4) radiant damage on a failed save, or half as much damage on a successful one.
  • False Appearance. While a mineral mephit remains motionless it is indistinguishable from a natural formation of rock and crystals.
  • Stone Ward (1/Day). As an action, a mineral mephit can innately cause its hide to harden and additional clusters of hard crystals to emerge on it, giving it resistance to nonmagical bludgeoning, piercing, and slashing damage for one minute. This effect does not require concentration. It requires no material components and its innate spellcasting ability is Charisma.


  • Fists. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 3 (1d6) bludgeoning damage plus 2 (1d4) radiant damage.
  • Crystal Breath (Recharge 6). A mineral mephit can exhale a 15-foot cone of crystal fragments. Each creature in that area must make a DC 11 Dexterity saving throw, taking 7 (2d6) slashing damage on a failed save, or half as much damage on a successful one.


Mineral mephits are composed of elemental Earth and Positive Energy, look like small, sturdy, winged creatures made of rock and covered with clusters of crystals, and are among the most attractive and self-assured monsters of their sort. They are also the strongest of the mephits, although this is not saying much in absolute terms. In addition to Terran, mineral mephits can speak the language of the Positive Energy Plane.
