Water Mastery (Ex): A water elemental gains a +1 attack and damage bonus if both it and its opponent touch water. If the opponent or elemental is landbound, the elemental suffers a -4 penalty to attack and damage. (These modifiers are not included in the statistics block.)
A water elemental can be a serious threat to a ship that crosses its path. The elemental can easily overturn small craft (5 feet of length per Hit Die of the elemental) and stop larger vessels (10 feet long per HD). Even large ships (20 feet long per HD) can be slowed to half speed.
Drench (Ex): The elementals touch puts out torches, camp-fires, exposed lanterns, and other open flames of non-magical origin if these are of Large size or smaller. The creature can dispel magical fire it touches as dispel magic cast by a sorcerer whose level equals the elemental's HD total.
Vortex (Su): The elemental can transform itself into a whirlpool once every 10 minutes, provided it is underwater, and remain in that form for up to 1 round for every 2 HD it has. In vortex form, the elemental can move through the water or along the bottom at its swim speed.
The vortex is 5 feet wide at the base, up to 30 feet wide at the top, and 10 feet or more tall, depending on the elemental's size. The elemental controls the exact height, but it must be at least 10 feet.
Creatures one or more sizes smaller than the elemental might take damage when caught in the vortex and may be swept up by it. An affected creature must succeed at a Reflex save when it comes into contact with the vortex or take the listed damage. It must also succeed at a second Reflex save or be picked up bodily and held suspended in the powerful currents, automatically taking damage each round. A creature that can swim is allowed a Reflex save each round to escape the vortex. The creature still takes damage, but can leave if the save is successful. The DC for saves against the vortex's effects varies with the elemental's size.
The elemental can eject any carried creatures whenever it wishes, depositing them wherever the vortex happens to be. A summoned elemental always ejects trapped creatures before returning to its home plane.
A water elemental prefers to fight in a large body of water where it can disappear beneath the waves and suddenly swell up behind its opponents.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Water. Creatures with the water subtype always have swim speeds and can move in water without making Swim checks. A water creature can breathe underwater and usually can breathe air as well.
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.
