Monster Manual II
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.
Spells: An earth weird can cast arcane spells and divine spells from the Earth and Destruction 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/ save DC 16 + spell level).
Earth Mastery (Ex): An earth weird gains a +1 bonus to attack and damage rolls if its foe is touching the ground.
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.
Earth Pool: This pool is filled with churning mud, and earth. Every creature within it (except the earth weird) takes 4d8 points of damage per round from the ever-grinding earth. In addition, creatures entering the pool suffocate they do not have a way to breathe and are entombed (unable to move) if they cannot burrow. An earth weird's pool may be affixed only to a horizontal surface, and it may appear only in a right side up position (such as in the floor of a cavern.
Tremorsense (Ex): An earth weird can automatically sense the location of anything within 60 feet that is in contact with the ground.
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 Earth Weird first appeared in the Monster Manual (Gary Gygax, 1977).
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
