Drench (Ex)

A water elemental construct’s touch puts out torches, campfires, exposed lanterns, and other open flames of non-magical origin if these are of Large size or smaller. The construct can dispel magical fire it touches as dispel magic (caster level equal’s the elemental construct’s HD).

Engulf (Ex)

A water elemental construct can simply engulf Large or smaller creatures in its path as a standard action. It cannot make a slam attack during a round in which it engulfs. The water elemental construct merely has to move over the opponents, affecting as many as it can cover. Opponents can make attacks of opportunity against the construct, but if they do so they are not entitled to a saving throw. Those who do not attempt attacks of opportunity can attempt a DC 36 Reflex save to avoid being engulfed—on a success, they are pushed back or aside (opponent’s choice) as the construct moves forward. Engulfed creatures are in danger of suffocating, and are trapped within its body until they are no longer pinned. The save DC is Strength-based.

Immunity to Magic (Ex)

A water elemental construct is immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and effects function differently against the creature, as noted below.

A control water spell or cold effect slows a water elemental construct for 2d6 rounds with no saving throw.

A horrid wilting spell deals 1d8 points of damage per caster level to a water elemental construct. The elemental construct can attempt a Fortitude save (DC 18 + caster’s relevant ability modifier) for half damage.

A create water spell heals 1d4 points of damage on the construct for each 2 gallons of water created.

Water Mastery (Ex)

A water elemental construct gains a +2 bonus on attack and damage rolls if both it and its foe are touching water. If the opponent or the elemental construct is touching the ground, the elemental construct takes a –4 penalty on attack and damage rolls. (These modifiers are not included in the statistics block.)


Environment Plane of Water
Organization solitary
Treasure none

Water elemental constructs are rare elemental constructs (perhaps as rare or rarer than fire elemental constructs) found in the palaces of the Water Elemental Princes or in the service of a powerful spellcaster or water deity. The are usually given the task of keeping secret or guarding an area underwater as this is their native environment and they do not function well outside of it.

A water elemental construct is a humanoid, 9 feet tall, composed of water. No discernible features can be seen on its head, though sometimes the face of an elemental spirit seems to appear randomly somewhere on its form.

A water elemental construct crashes down on its opponents with watery fists before attempting to grab a foe and stuff it into its watery form. An engulfed foe is held until it drowns; thereafter, the elemental construct expels the creature’s corpse onto the ground.
