Elemental Command (Su): A weird can attempt to gain control over any elemental within 100 feet regardless of the latter's elemental type. The elemental must make a successful Will save (DC 23) or succumb to the weird's control. An elemental that saves against this attack it immune to that weird's elemental command ability for 24 hours. There is no limit to the number of elementals that a weird can control.

Once under the weird's control, an elemental serves the weird until either it or the weird dies, until the weird dismisses it, or until the duration for its summoning expires. It obeys the weird explicitly, even if ordered to attack the being who originally summoned it. The weird does not need to concentrate to maintain control over any elemental it commands.

Elemental Traits (Ex): An elemental weird is immune to poison, sleep, paralysis, and stunning. It is not subject to critical hits or flanking, and it cannot be raised or resurrected. The creature also has darkvision (60-foot range).

Prescience (Su): At will and as a free action, a weird can duplicate the effect of any of the following divination spells: analyze dweomer clairaudience/clairvoyance, contact other plane, detect thoughts, discern location, find the path, foresight, greater scrying, legend lore, locate creature, locate object, tongues, true seeing, vision. Caster level 18th; save DC 16 + spell level.

Burn (Ex): Any creature that is hit by the fire weird's slam attack (or that hits the fire weird with a natural weapon or an unarmed attack) must succeed at a Reflex save (DC 20) or catch fire (see Catching on Fire in Chapter 3 of the DUNGEON MASTER's Guide). The fire burns for 1d4 rounds.

Spells: A fire weird can cast arcane spells and divine spells from the Fire and Sun domains as an 18th-level sorcerer (spells known 9/5/5/4/4/4/3/3/2/1; spells/day 6/8/8/7/7/7/7/6/5/3; save DC 16 + spell level).

Elemental Pool (Su): Each weird dwells within a large pool (at least 20 feet across and 40 feet deep) filled with the purest form of its element. The pool is always secured to a flat surface such that its depth forms a hollow within that surface. The surface must have sufficient depth to accommodate the pool. An elemental pool can also exist as a separate area inside a larger volume of the same element.

The base of the pool contains a portal to the weird's native plane. Three times per day, the weird can summon forth 2d4 huge elementals, 1d2 greater elementals, or 1 elder elemental through this portal. Any non-elemental creature entering a pool without the weird's permission must succeed at a Fortitude save (DC 20) each round or be irrevocably transformed into the elemental material of the pool. Creatures granted access to the pool by the weird are not subject to transformation. However, creatures allowed to enter a pool must still provide their own protection from the elemental material, as well as the means to breathe and move within that environment.

A weird is physically tied to its pool and cannot leave except to return to its native plane through the portal. A weird may rise up to a height of 10 feet above the surface of its pool, but the lower part of its body must always remain in contact with the elemental material. Once a weird exits the pool for its native plane, the portal closes, and the pool loses its special effects.

Fire Pool: This pool contains a torrent of dancing flames that burn and smoke continually. Unprotected flammable materials within a fire pool catch on fire immediately, and any creature within the pool takes 3d10 points of fire damage per round. Creatures without the ability to fly cannot move through this pool, except by falling. A fire weird's pool may be affixed to any vertical or horizontal surface, and it may appear only in a right side up position (such as on the floor of a cavern).

Fire Subtype (Ex): A fire weird is immune to fire damage but takes double damage from cold unless a saving throw for half damage is allowed. In that case, the creature takes half damage on a success and double damage on a failure.

Elemental weirds do not fight if they can avoid it. If they must fight, they begin by summoning elementals to defend them. If any other elementals are present (regardless of type), the weird attempts to gain control of them and turn them against its foes. Meanwhile, the weird remains in the center of its pool, using divination magic to foresee possible consequences of the battle and acting accordingly. If forced into melee, a weird uses its reach to lash out at nearby foes. If seriously threatened, a weird retreats back to its plane of origin.

The Fire Weird first appeared in the Monster Manual (Gary Gygax, 1977).

Fire Subtype

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.
