Tempest

Though it resembles a massive storm, a tempest is actually an intelligent, living creature related to both elementals and genies. All four elements coexist within its form: air in the wind, earth in the whirling sand and dirt, fire in the heat of the lightning, and water in the rain.

Tempests are uncommunicative for the most part. Very rarely, one of them may know a few dozen words in Common. Other than that, they speak only the languages of the elementals.

Combat

A tempest is seldom in a good mood, so most encounters with these creatures end in a battle.

Burn (Ex): Anyone hit by a tempest’s slam attack must succeed at a Reflex save (DC 31) or catch fire. The flame burns for 1d4 rounds. A burning creature can take a moveequivalent action to put out the fire. Any creature hitting a tempest with a natural weapon or unarmed attack takes fire damage as though hit by its slam attack and also catches fire unless it succeeds at a Reflex save.

Drench (Ex): The tempest’s touch puts out torches, campfires, exposed lanterns, and other open flames of nonmagical origin if these are of Huge size or smaller. The creature can dispel magical fire it touches as if by dispel magic (caster level equal to tempest’s HD). The tempest can choose not to activate this ability (in order to not extinguish the flame of an opponent affected by its burn attack, for example).

Spell-Like Abilities: At will⁠—​chill touch, gust of wind, lightning bolt, wind wall. Caster level 9th; save DC 13 + spell level.

Whirlwind (Su): A tempest can transform itself into a whirlwind (or vortex if underwater) once every 10 minutes and remain in that form for up to 1 round for every 2 HD it has. The whirlwind is 5 feet wide at the base, up to 30 feet wide at the top, and between 10 and 50 feet tall (tempest’s choice). In this form, it can move through the air (or water, as a vortex) or along a surface at its fly speed.

Any creature one or more size categories smaller than the tempest that comes into contact with the whirlwind must make a successful Reflex save (DC 31) or take 4d6 points of damage. It must also succeed at a second Reflex save (DC 31) or be picked up bodily and held suspended in the powerful winds, automatically taking 4d6 points of damage per round. A creature that can fly is allowed a Reflex save at the same DC each round to escape the whirlwind. The creature still takes damage but can leave if the save is successful. The tempest can eject any carried creatures whenever it wishes, depositing them wherever it happens to be.

If the whirlwind’s base touches the ground, it creates a swirling cloud of debris. This cloud is centered on the tempest and has a diameter equal to half the whirlwind’s height. The cloud obscures all vision, including darkvision, beyond 5 feet. Creatures 5 feet away have one-half concealment, while those farther away have total concealment. Anyone caught in the cloud must succeed at a Concentration check (DC 31) to cast a spell.

Defensive Aura (Sp): A tempest has a +10 deflection bonus to Armor Class. This ability is always in effect.

Elemental Mastery (Ex): A tempest gains a +1 bonus on attack and damage rolls if both it and its foe are in contact with any of the four elements (air, earth, fire, or water).

Elemental Traits (Ex): A tempest is immune to poison, sleep, paralysis, and stunning. It is not subject to critical hits or flanking, and it cannot be raised or resurrected.
