Siyokoy

CR 10.00 Aberration N Medium HD 13
This eel-like creature sports sharp frills that run along the back of humanoid torso and down its long, powerful tail.

Siyokoys are eel-like aquatic creatures often mistaken for merfolk by sailors. On closer inspection, however, siyokoys' appearance might make one question the vision of said sailors, for apart from their humanoid arms, siyokoys are very much creatures of the sea.

Two primary species of siyokoys exist, although both are essentially identical as far as game statistics are concerned. The most commonly encountered siyokoys are those that dwell amid the caves and crags of coral reefs in relatively shallow oceanic waters. These siyokoys tend to have colorful patterns on their flesh to mimic the riot of hues the typical coral reef displays. Reef-dwelling siyokoys are fond of decorating their lairs with particularly strange or colorful specimens of coral, especially when such marine growths encrust sunken treasures.

A siyokoy variant that is encountered less frequently dwells in the deeper abysses of the ocean, far below the limits of the sun's ability to light. These siyokoys are darker colored, and they tend to be darker in personality as well. Whereas those dwelling in the bright, sunlit environs of a coral reef might be capricious or playful, those who dwell in the dark, vast deeps of the sea are often morbid, morose, and even sadistic. Most evil siyokoys dwell in such lightless, forgotten reaches of the world's oceans.

Regardless of where they dwell, siyokoys adore shipwrecks and long-forgotten ruins claimed by the oceans. Exploring these relics and recovering strange and wondrous treasures is what most siyokoys live for, and a siyokoy's lair is often decorated with the results of these scavenging expeditions to sunken ships and flooded cities. Strangely, siyokoys avoid making their lairs amid such ruins, mostly out of a strange superstition the creatures share about these areas—it is not lucky, say siyokoys, to sleep in a place where air breathing creatures have drowned.

A siyokoy is 7 feet long and weighs 200 pounds.

constrict (2d6+4)

Stunning Shock — A siyokoy can emit a strong electrical charge from its tail. When it hits a creature with its tail slap, the attack deals 3d6 points of electrical damage and the target must succeed at a DC 22 Fortitude save or be stunned for 1d4 rounds. The save DC is Constitution-based.

Swim-By Attack — Extremely quick in the water, a siyokoy gains Spring Attack as a bonus feat when swimming.

Universal Monster Rules

Grab
Grab (bite) Ex from Universal Monster Rule
If a creature with this special attack hits with the indicated attack (usually a claw or bite attack), it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply to use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its combat maneuver check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature's descriptive text). Creatures with grab receive a +4 bonus on combat maneuver checks made to start and maintain a grapple. Unless otherwise noted, grab works only against opponents no larger than the same size category as the creature. If the creature can use grab on sizes other than the default, this is noted in the creature's Special Attacks line.
Constrict (2d6+4) Ex from Universal Monster Rule
A creature with this special attack can crush an opponent, dealing bludgeoning damage, when it makes a successful grapple check (in addition to any other effects caused by a successful check, including additional damage). The amount of damage is given in the creature's entry and is typically equal to the amount of damage caused by the creature's melee attack.
