Breath Weapon (Su): Cone of steam, 10 feet; damage 1d4, Reflex half DC 12. Living creatures that fail their saves are tormented by burned skin and seared eyes unless they are immune to or protected from fire. This imposes a -4 morale penalty to AC and a -2 morale penalty to attack rolls for 3 rounds. A mephit can use its breath weapon once every 1d4 rounds as a standard action.
Spell-Like Abilities; Once per hour a steam mephit can surround itself with a plume of vapor, duplicating the effects of a I spell cast by a 3rd-level sorcerer (save DC 12 + spell level). Once per day it can create a rain-storm of boiling water that affects an area 20 feet square. Living creatures caught in the storm take 2d6 points of damage (Reflex half DC 15).
Fire Subtype (Ex): Fire immunity, double damage from cold except on a successful save.
Fast Healing (Ex): A steam mephit heals 2 points of damage each round, only if it is touching boiling water or is in a hot, humid area.
Summon Mephit (Sp): Once per day, all mephits can summon other mephits much as though casting a summon monster spell, but they have only a 25% chance of success to summon one mephit of the same type. Roll d%: On a failure, no creature answers the summons. A mephit that has just been summoned cannot use its own summon ability for 1 hour.
A creature with the fire subtype has immunity to fire. It has vulnerability to cold, which means it takes half again as much (+50%) damage as normal from cold, regardless of whether a saving throw is allowed, or if the save is a success or failure.
A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.
Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
