Planar Bestiary
The storm-tossed Plane of Water holds many things, including catastrophes of elemental fury more dire than the elementals that are normally conjured and bound. From time to time, just such a shape of water finds their way to a Material Plane world, summoned by a risk-taking spellcaster or flooding in from a crack in the firmament.
A shape of water is a huge roiling blot of fluid given form and purpose, a living whirlpool that hungers for destruction of things not of the sea.
A creature of animate fluid, a shape of water doesn't require air, food, drink, or sleep.
Motive: Destruction, or obedience to their summoner
Environment: The Plane of Water or a world of the Material Plane they leaked into or were summoned into, alone or in the company of their summoner
Health: 36
Damage Inflicted: Moderate wound (7 points)
Armor: 1
Movement: Short; long when swimming
Modifications: Speed defense as level 5 due to huge size; resists being grabbed or otherwise entangled as level 10; damages objects as level 8
Combat: The shape of water attacks twice each round with a turbulent slam.
A shape of water can try to immerse targets within immediate range once every couple of rounds. Targets that fail a Might defense task take damage and are immersed within the shape of water's liquid embrace, spinning around and around until they can escape with a successful Might-based task. All an immersed target's physical tasks are hindered, and they automatically take damage from the turbulence each round. Immersed targets are also at risk of drowning if they can't breathe water; every three rounds they go without air, they descend one step on the damage track.
The shape of water can produce a foam-crested tsunami of magical water every few rounds, targeting an adjacent area a long distance in diameter. Each creature in the wave's area takes 10 points of damage on a failed Speed defense task, or 3 points even if successful. Structures in the area are subject to this attack as well.
The shape can move through tiny cracks, though their movement is reduced to an immediate distance each round they do so, and they can't attack or defend until they reform themself on the opposite side as an action.
The shape of water is immune to poison attacks but vulnerable to cold; every time they take 1 point of cold damage, they take 1 additional minor wound (1 point).
Interaction: A shape of water can speak the language of water elementals (Aquan). However, rather than converse, a shape is usually bent on destruction if encountered outside the Plane of Water and not under the command of a summoner.
Use: A battleship of the old kingdom went down at sea during an ancient conflict. Some drowned magical weapon on that rotting craft lately malfunctioned; every few weeks, it summons an enraged shape of water, which breaks to the surface and goes after the nearest ship or coastal city.
GM Intrusion: The shape of water immediately makes another slam attack even though it's not the elemental's turn.
GM Intrusion: The shape of water immediately moves their speed and makes a tsunami attack, even though it's not the elemental's turn.
