Magma MephitSmall elemental
Death Burst. When the mephit dies, it explodes in a burst of lava. Each creature within 1 meter of it must make a DC 11 Reflex saving throw. On a failed save, a creature takes 7 (2d6) fire damage and is burning 1. On a successful save, a creature takes half as much damage and isn’t burning. Flammable objects that aren’t being worn or carried in that area are ignited.
False Appearance. While the mephit remains motionless, it is indistinguishable from an ordinary mound of magma.
Spellcasting. The magma mephit’s spellcasting ability is Charisma (spell save DC 10, +2 to hit with spell attacks). It has 1 mana, a mana limit of 1, regains all expended mana when it finishes a long rest and regains half its total mana (rounded up) when it finishes a short rest. It knows the following spells:
Claws. Melee Weapon Attack: +3 to hit, reach 1 m. Hit: 3 (1d4 + 1) slashing damage plus 2 (1d4) fire damage.
Variant: Summon Mephits (1/long rest). The mephit has a 25 percent chance of summoning 1d4 mephits of its kind. A summoned mephit appears in an unoccupied space within 10 meters of its summoner, acts as an ally of its summoner, and can’t summon other mephits. It remains for 1 minute, until it or its summoner dies, or until its summoner dismisses it on its turn (no action required).
No concoctions, maneuvers, or spells
All monsters in this system should have maneuvers or spells. You should add some maneuvers or spells to this monster. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all monsters via https://github.com/mlenser/kryx-rpg-issues/issues/9
