Ludroth

Ludroth are mostly yellow-green in coloration, with long, sinewy bodies that enable swift and sweeping underwater movements to confuse their prey. Their claws are stubby, but effective, and their strong tails end in reinforced bony segments. Powerful jaws allow for moderately strong biting attacks. The majority of Ludroth are female, and form harems around the male Royal Ludroth.

Royal Ludroth

It has a crown-like crest composed of several finger-like appendages tipped with black spikes as well as a large, spongy yellow mane. The Royal Ludroth has a long, serpentine body with four squat limbs. Its hind pair of legs are shaped like paddles for swimming, and its foremost pair are more muscular, tipped with developed digits ending in long black claws. Its jaws are lined with shear-like plates in the place of teeth.

As the alpha male, Royal Ludroth will usually roam around with a harem of females in tow. It is an aggressive creature, and will lash out at anything that threatens it or its clan.

Uroktor

Leviathans that inhabit volcanoes. Noted for swarming around larger monsters' kills in order to feed. Uroktor rarely hunt for themselves, but are known for being highly aggressive. Just like their adult form, the Agnaktor, they have the remarkable ability to tunnel through solid volcanic rock. Uroktor are distinguished by their reddish-purple skin, which protects them from both the sweltering heat and volcanic predators. Uroktor will defend themselves from other monsters and adventurers alike, but will flee if they feel overwhelmed.

Agnaktor

Also known as Fire-Pike Wyverns, Agnaktor has developed the remarkable ability to swim through lava, meaning it can both sneak up on prey and escape from a more powerful enemy. It has a very strong beak, which it uses to burrow straight through hard volcanic rock at incredible speeds. While swimming it swallows some of the lava and stores it in its body so that it can produce its powerful lava beam. Produced between Agnaktor's scales is a non-flammable substance that never burns. This substance allows Agnaktor to coat its hide with lava and swim in lava. The molten rock on its body will eventually harden into a thick armor of rock, but when the Agnaktor touches lava, its coating becomes soft again.

Despite Agnaktor being powerful predators, they are known to leave their habitat when a powerful monster appears or during a volcanic eruption. During the Breeding Season, both males and females will swim to the summit of an active volcano to mate, this is also where most Agnaktor learn the dig through the ceiling technique. The female will then make a nest somewhere near the top and then give live birth to 2-30 individuals at a time.

Gobul

Gobul is a uniquely evolved Leviathan reminiscent of angler and puffer fish. Its body is covered in purple scales, and a bright, bioluminescent lure dangles from its forehead. It possesses a gargantuan mouth filled with equally formidable teeth. Its back features an array of retractable spines, and its tail is tipped with quills containing powerful neurotoxins, which can paralyze both predator and prey. The Gobul doesn't produce these toxins, but receives them through its food. The neurotoxin exists in the ecosystem in small quantities and gets concentrated to the top of the food chain. Gobul uses this toxin mainly for self-defense, but they will sometimes use it to paralyze its prey during mimicry.

Gobul's massive mouth and throat mean that it can swallow prey almost as large as itself completely whole. Its lure can violently emit blinding flashes of light to disorient prey to make for an easy meal. Luminescent micro-organisms are cultured in Gobul's lantern sphere, and are stimulated by shaking. It could be said that the microbial organisms that are emitting the intense light have a symbiotic relationship with the Gobul. Another theory suggests that by shaking its lantern, Gobul secretes a substance that causes a chemical reaction with the microbes to cause the flash.

It is capable of puffing out its body like a balloon to appear more imposing.

Gobul has a display of whiskers on its chin, mimicking air weeds. It leaves these whiskers to flow in the water to both hide itself and draw prey in. This natural camouflage ability is enhanced further by Gobul's ability to change the color of its skin, like a chameleon allowing it to blend into the river floor and remain undetected by prey.

Lure. While hidden, the gobul can use the lure on its head to create a mesmerizing flash of lights. Any creature that can see the lure, must make a DC 13 Wisdom saving throw or be charmed for 1 minute by the gobul or until the gobul something harmful to the creature. While charmed in this way, the creature may only use its turn to move towards the lure.

Natural Camouflage. While the gobul remains motionless on river bed, lake bottom, or sea floor, it is indistinguishable from common water plants.

Amphibious. The gobul can breathe air and water.

Actions

Multiattack. The gobul makes two attacks: one with its bite and one with its tail. It can't make both attacks against the same target.

Tail. Melee Weapon Attack. +7 to hit, reach 10 ft., one target. Hit 15 (2d10 + 4) piercing damage, or 20 (3d10 + 4) piercing damage while enlarged.. On hit, the target must make a DC 15 Constitution saving throw or become poisoned for 1 minute. While poisoned in this way, the target is paralyzed. The target can repeat the saving throw at the end of each of its turns , ending the effect on itself on a success.

Bite. Melee Weapon Attack. +7 to hit, reach 5 ft., one target. Hit 13 (2d8 + 4) piercing damage, or 17 (3d8 + 4) piercing damage while enlarged.

Enlarge (Recharges after a Short or Long Rest). For 1 minute, the gobul magically increases in size, along with anything it is wearing or carrying. While enlarged, the gobul is Huge, rolls one additional weapon damage die on Strength-based weapon attacks (included in the attacks), and makes Strength checks and Strength saving throws with advantage. If the gobul lacks the room to become Large, it attains the maximum size possible in the space available.

Swallow. The gobul makes one bite attack against a Medium or smaller creature that is paralyzed or charmed. If the attack hits, the target takes the bite's damage and the target is swallowed. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the gobul, and it takes 10 (3d6) acid damage at the start of each of the gobul's turns. The gobul can swallow 3 creatures while enlarged, or 2 when not enlarged.
If the gobul takes 19 damage or more on a single turn from a creature inside it, the gobul must succeed on a DC 17 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the gobul. If the gobul dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 10 feet of movement, exiting prone.

Vortex (recharge 5-6). While underwater, the gobul opens its mouth swallowing everything in a 30-foot cone. Each creature in that area must make a DC 15 Strength saving throw. On a fail, the gobul swallows that creature without making a bite attack, even if the creature is not paralyzed or charmed. If the gobul cannot swallow all the creatures, it swallows the closest ones first and may use a bonus action to bite one additional creature that failed the saving throw.

Blinding Flash The gobuls bioluminescent lure emit blinding flashes of light in a 30-foot radius. Each creature in the area, must make a DC 15 Constitution saving throw or become blind until the end of their next turn.

Blind. The gobul uses Blinding Flash.

Devour. The gobul uses its bite attack; or Swallow on a paralyzed or charmed creature.

Roll (Must be Enlarged). The gobul extends it retractable spines on its back. It then can move up to half its movement speed, without provoking an attack of opportunity, by rolling over and impaling anything in its path. Each creature in that area must make a DC 13 Dexterity saving throw, taking 11 (2d6 + 4) piercing damage and are paralyzed for 1 minute on a failed save. On a successful save the creature takes half damage and is not paralyzed.

Reactions

Sand Cloud. When a creature makes an attack against the nibelsnarf, it can use its reaction to expel a large sand cloud from the gills on the back of its head. Any creature within 5 feet of the nibelsnarf and flanking it must make a DC 15 Strength saving throw or be knocked prone. If a creature fails the save by more than 5 they are also pushed 10 feet away from the nibelsnarf.

Nibelsnarf

Leviathans that have adapted to live in sandy areas. They burrow through sand and locate prey aurally, then suck both the target and any surrounding sand into their maws. It has the remarkable ability to swim in sand, shared only with a few monsters, and its streamlined body helps it move through it at great speeds. They are capable of burrowing into the sand and of disguising themselves as sand dunes to ambush prey.

It has a huge mouth for eating its prey such as Rhenoplos in one bite, like the Gobul. It locates its prey with hearing. It shares this trait with the Agnaktor, which is also a land dwelling Leviathan. It is possible that the two developed this ability because they spend most of their time underground. It spits sand at predators that try to attack it. Its eyes are on top of its head, so it can see its prey easier when lurking in the sand; however, their placement also makes it difficult for it to see anything directly in front of it. They also have salamander-like "gills" which it uses to filter out sand and absorb minerals in the sand. It uses this clearing of the sand as an attack, as the sand shoots from the gills at a high enough speed to hurt individuals caught in the blast. Nibelsnarf seem to have very strong stomachs, capable of withstanding a bomb exploding in it. Inside the massive mouth of this predator is an enlarged uvula that stores nutrients. This organ is essential to the leviathan's survival within the arid Sandy Plains.

Mizutsune

Like most other Leviathans, Mizutsune has a long, slender body. However, it is one of the few Leviathans to actually have fur on its body. This fur covers its chest, underbelly, legs and tail. Its scales are light colored and resemble those of a fish. Its head has a long snout and is beautifully adorned by many fin-like appendages. These fins are pink with yellow markings, and they can also be seen on its back and tail. Its feet are said to be quite different from other Leviathans and allow Mizutsune to move swiftly on land.

Mizutsune's most unique adaptation is its ability to produce bubbles. It is able to produce the bubbles by using special fluid secretions, produced from its own body along with water, and rubbing its hairs in the secretions. These stiff yet soft purple hairs are found on its chest, tail, legs, and sides. The hairs are used for sliding on the fluids it produces, spreading the fluids, and even using the fluids to produce more bubbles. Mizutsune can also breath these bubbly fluids from its mouth. It is known to use the bubbles it produces both offensively and defensively in battle. It uses the bubbles to help it move faster and to make it more flexible in battle, while simultaneously impeding the movement of any foes. In order to stop itself quickly while moving, Mizutsune has special hook-like claws that allow it to stop sliding quickly to face threats and not leave itself open. Despite Mizutsune's strange appearance, the fins it has actually act as receptors for detecting the presence of predators and prey coming through vibrations in the secretions. Like a snake, Mizutsune's teeth are recurved to prevent prey from escaping easily. Its jaws are even designed like a snake to an extent, even being able to open its mouth wide and swallow some large prey. It can also fire pressurized jets of water from its mouth, much like Plesioth.

Mizutsune are rather calm in nature until provoked. They prefer to be left alone resting near large bodies of water, while covered in their special secretions. They prefer to avoid confrontations, however, will defend themselves if need be. Once a threat has left, Mizutsune won't chase after the threat but will instead let it go. Though Mizutsune are usually calm, they are known to turn aggressive during Breeding Season. Mizutsune become aggressive or even berserk during their Breeding Season. In this season, it is not a good idea to go fishing from them being known to injure people due to their blind rage. Male Mizutsune have large fins and are able to flash their fins red to show emotion to the female Mizutsune, in order to attract them.

Oiled Body. The mizutsune has advantage on Dexterity (acrobatic) checks.

Actions

Multiattack. The mizutsune makes three attacks: one with its bite and two with its tail. It can make both attacks against the same target.

Tail. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit 25 (3d12 + 6) bludgeoning damage. On hit, the creature is Slick.

Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit 19 (3d8 + 6) piercing damage. If the target is a Large or smaller creature, it is grappled (escape DC 14). Until this grapple ends, the mizutsune can't use its bite on another target.

Bubble Prison. Range Weapon Attack: +10 to hit, range 80/320 ft., one Large or smaller creature. Hit: The creature is Slick and enclosed in a bubble of shimmering force for 1 minute or until the bubble is destroyed. Nothing, not physical Objects, energy, or other spell effects, can pass through the bubble, in or out, though a creature in the Sphere can breathe there. A creature inside of the bubble has disadvantage on attacks due to its slippery nature. The bubble has AC 15, 30 hit points, resistance to bludgeoning damage, immunity to poison and psychic damage, but vulnerable to piercing damage. At the end of the mizutsune's turn all bubbles rise 10 feet higher into the air.

Hydropump (recharge 5-6). The mizutsune releases a high pressure stream of water in an 60-foot line that is 5 feet wide. Each creature in that line must make a DC 18 Dexterity saving throw, taking 55 (10d10) cold damage on a failed save, or half as much damage and not on a successful one.

Reactions

Tail Sweep. When a creature is slick and starts its turn within 10 feet of the mizutsune. It can use its reaction to sweep its tail, hitting the targets legs. The target must then make a DC 18 Dexterity saving throw or be knocked prone.

Tetsucabra

Tetsucabra is a large Amphibian with a striking orange and indigo coloration. Its lower jaw harbors large tusks along with a large set of molars that are capable of crushing prey with ease. Tetsucabra also has a spiky stubby tail that swells up when angered.

The scales of a Tetsucabra is used mainly for camouflage inside caves and on them is a special oil that holds heat. Despite the look of the scales, its skin is actually flexible yet hard somewhat resembling an actual toad's skin. A Tetsucabra's skull is robust and durable enough to take a lot of damage from threats of all sorts. Though the Tetsucabra has two large tusks, these are not used for hunting. The primary function of these tusks is for defense and as means to manipulate the environment. The tusks themselves are capable weapons, but the Tetsucabra is also capable of hefting up heavy boulders. The Tetsucabra flings these boulders out of the way of its path but it can also use this as a method of attack to injure predator and prey alike. It uses these boulders as a shield against predators and hunters to prevent attacks. It also uses this to enclose small, tight areas, making it harder to maneuver. Another fact about the Tetsucabra is its ability to spit a glob of fluid at prey items. This sticky material acts as a powerful adhesive, sticking to the body and ground like glue. Even for a hunter, the adhesive quality of this material is not very strong, but it makes every movement a labor and greatly weakens the prey, leading to a reduction in stamina. When the Tetsucabra exerts itself, its tail inflates, possibly to help it balance itself as it picks up large boulders and rocks. The legs of a Tetsucabra help it perform powerful leaps, lunges, and jumps in the air to help it either ambush prey or to reach steep slopes out of its reach. A Tetsucabra's claws are powerful enough to break rock with ease and can destroy powerful armor.

Tetsucabra are highly aggressive, territorial monsters though their ecology is much like a frog. The amphibians are well-known for attacking and eating anything that moves in their line of sight and leaping from ponds in order to grab potential prey. Despite being found in ponds, they spend most of their time on land, which could suggest that they patrol their territory on land, much like Zamtrios. During the breeding season male Tetsucabra will create large holes to impress females so that they'll lay their eggs in them. When the female lays her eggs in the pit the male will quickly fertilize them. After fertilizing the eggs the male will then carry them in his mouth and he will not eat anything until the offspring are fully developed.

Zamite

It is a small, shark-like creature whose relatively large mouth houses many rows of teeth made for attacking prey and hunters. Zamite have been sighted in a number of different stages of development, with some having fully developed legs, while others slide on their bellies. During battle, Zamite can grow larger when it ingests bodily fluids. These fluids also allow Zamites to grow legs if they are ingested by the individuals without limbs. Zamite behave just like Giggi in the manner of aggressively attacking any possible food source and draining them of their vital fluids.

Zamtrios

Zamtrios is a large, quadrupedal monster with grey-blue skin and yellow fins. It is superficially shark-like in appearance, with a long, pointed snout and a mouth filled with multiple rows of sharp teeth. As the adult form of Zamite, its limbs are powerful and fully-developed. Its skin is extremely elastic in order to accommodate its inflation abilities.

Zamtrios is a powerful predator, but these Fanged Beasts mostly feed on plants, nuts, and mushrooms though they will sometimes eat meat. From the size of the Lagombi, it's very possible Zamtrios would try to hunt them. Though Zamtrios prefer to feed on smaller helpless prey, they are still quite dangerous in their own right. Zamtrios have even been found to feed on Plesioth in tropical waters. The massive and aggressive Gammoth can seriously injure, if not outright kill the Amphibian if confronted.

Zamtrios is a very strange Amphibian with many bizarre adaptations. Zamtrios now lacks the sharp spike its juvenile form has but now is able to produce a type of "armor". It is able to produce this armor by secreting a special fluid from its skin that eventually freezes around it forming this icy armor. This armor acts as a secondary protection against threats and also acts as weapon. When it forms this armor, it will also produce a long, rigid spike made of ice on top of its head, replacing the spike it once had, and spike on its tail as another weapon. When its not using its icy armor it will use freezing water to attack threats or prey from a distance and will spit balls of snow at them to stop their movement. Zamtrios have an under layer of skin directly under their skin used to replace previous old one. Their teeth, like saws, cut up prey just by rubbing against them.

When Zamtrios is damaged greatly while it has its icy armor, it will go through one of the most dramatic changes in nature. When greatly damaged, Zamtrios will greatly expand its body and inflate its body to several times its original body size. It goes through this change to intimidate an attacker and is able to do this from gas that it produces from inside its body. The downside to this is that Zamtrios becomes more susceptible to attacks while inflated and its maneuverability is dramatically decreased.

Zamtrios primarily spend most of their time in the water or under ice, constantly roaming around their territory and searching for prey. Like the Zamites, Zamtrios have huge appetites and have a single mind set on finding prey and to kill or eat any intruders in their territory. If Zamtrios have an enemy in their sight, they may actually chase them for miles upon miles of ice. During the breeding season Zamtrios will come together and mate. When female Zamtrios have mated they will then lay their eggs within the ice.

Each of those creatures must succeed on a DC 18 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 22 (4d8 + 4) bludgeoning damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the daimyo hermitaur's space into an unoccupied space of the creature's choice. If no unoccupied space is with in range, the creature instead falls prone in the daimyo hermitaur's space.

Reactions

If the target is a creature other than an undead or a construct, it must succeed on a DC 10 Constitution saving throw or lose 2 (1d4) hit points at the start of each of its turns due to an bloody wound. Each time the ceanataur hits the wounded target with this attack, the damage dealt by the wound increases by 2 (1d4). Any creature can take an action to stanch the wound with a successful DC 10 Wisdom (Medicine) check. The wound also closes if the target receives magical healing.

The target can repeat the saving throw at the end of each of its turns , ending the effect on itself on a success.

Ceanataur

Similar in appearance to the Hermitaur with sharper claws, leg stubs and a higher-edge shell. The shell on its back was actually grown by the Ceanataur itself. Only when it grows much larger into a Shogun Ceanataur will it replace its shell with a larger monsters skull, like a Gravios skull.

It is able to spit a small ball of poisonous fluid at foes. Sometimes, a Ceanataur may wait beneath the ground for prey or a hunter to pass, jumping out of the ground and striking them when they walk over. A Ceanataur that's burrowed underground can be spotted by the puffs of dust that it regularly spits out.

Ceanataur are very aggressive towards anything that threatens. They are well-known for chasing adventurers down in order to attack them. While young, Ceanataur are quite low in the food chain. They are known to feed on smaller species and anything else they can get their claws on. Ceanataur will even attempt to feed humans.

Shogun Ceanataur

Shogun Ceanataur is a Carapaceon. However, they hardly resemble their cousins, the Daimyo Hermitaur. Shogun Ceanataur's body is covered in a blue carapace. Its head is long and knife-shaped, and features a pair of lengthy antennae. Its folding claws act as sickles, that fully extended, adding a significant amount of range to its reach. Shogun Ceanataur is known to inhabit a variety of shells, among them: A Gravios skull, a snail-like shell, and a skull belonging to an unknown wyvern.

Compared to Daimyo Hermitaur, Shogun Ceanataur has a much slimmer shape. From the lighter shell of Shogun Ceanataur, it is able to move faster than Daimyo Hermitaur. With this lighter armor, Shogun Ceanataur are also able to attack and move offensively rather than defensively. Another bizarre defense of Shogun Ceanataur is its own urine. While wearing a skull and hanging on a ceiling, Shogun Ceanataur are known to spray water on their enemies from the ceiling.

Each Shogun Ceanataur has their own personality. Some are more aggressive than others. When undisturbed, Shogun Ceanataur are usually fairly calm, however, if threatened, they will turn aggressive in an instant. They’ll unsheathe their claws and will attempt to kill a foe. If the skull on Shogun Ceanataur's backside is broken, it'll immediately go looking for another one, so it can protect its vulnerable bottom.

Shogun Ceanataur are somewhat high in the food chain. They primarily feed on small creatures that live in dark environments like shrimp and insects, but will also feed on carrion. Despite this, they can more than hold their own against larger species. They are also known to have battles with Khezu and other Shogun Ceanataur in the caves of the swamp.

Cephalos

Cephalos' body shapes are streamlined and flat, to help them swim through the sand. They have a vaguely hammer-shaped head, with eyes that face upwards. Their brown and beige coloration helps them camouflage themselves among the desert sands. These monsters are surprisingly social, swimming through the loose sand and hunting in packs. They are predatory, and can work together to defeat creatures many times their size.

From spending large amounts of time swimming in the sand, their eyesight has become very poor and now they are nearly blind. Instead Cephalos listen for not only for the footsteps of prey but, also for the breathing of prey. If the sounds are extremely loud, they will be shocked out the ground and stunned by the loud noise. To stay cool in the heat of the desert, its scales hold large amounts of moisture in its body, allowing for more activity in its environment. They can't breath in the sand so they have to occasionally jump out the sand in order to breath air. While swimming, however, they will swallow some of the sand as they swim. The swallowed sand is stored in a special organ in their body, that combines sand with its mucus, and saves this sand as a weapon to injure prey.

The true color of a Cephalos is blue, or rarely purple, but over time sand sticks to their bodies covering the blue coloration. Mildly aggressive, Cephalos are known for gathering in packs and hunt alongside their leaders, Cephadrome. They are also known for migrating to different parts of the desert when food sources are drained.

Cephadrome

Cephadrome have yellow eyes, yellow or pink fins and blue or purple scale covered skin. This skin appears brownish black due to sand covering their body. They have a flat, diamond-shaped head (much like a hammerhead shark or a Diplocaulus, an extinct prehistoric amphibian), fins, and tail, which helps propel them through the sand.

Cephadrome are very aggressive, however, it will assume evasive maneuvers if it senses that the threat is too dangerous. Cephadrome swims in sand to avoid danger, then attacks unexpectedly to startle its foe. It also uses a sand "spray" to attack from a distance. A leader its role may be as a main attacker. A Cephadrome is also very protective of the Cephalos in its pack. They will attack larger predators or even the aggressive Diablos to distract the foe away from its pack.

Interestingly, the life of these creatures begins in water. The females will lay their eggs in an oasis and those eggs will hatch during the dry season. After the offspring hatch they will swim in the mud and as it dries it will become much tougher for the hatchlings to swim in. When the mud begins to turn into sand the hatchlings will slowly learn to swim through the sands of the desert and it is very important that they do so.

Delex

They have, like the Cephalos, the ability to "swim" through sand and even expel small sand blasts from their mouth at attackers. Due to their nimbleness they are difficult to hit. Several appear in the fights with Jhen Mohran and Dah'ren Mohran, jumping onto the boat and attacking Hunters that get in their way. Delex hunt in small groups of six or seven individuals and likely prey upon small animals. They also scavenge off the remains left by larger desert-dwelling monsters.

Gajau

Gajau have greenish scales with orange dorsal fins. They resemble catfish in appearance. Gajau are vicious predatory fish that will attack anything. Gajau will even jump out of the water to capture prey.

Lavasioth

Lavasioth is a bipedal Piscine Wyvern that resides in lava rather than water. Its body is covered with hardened magma, forming a tough outer shell. Its head is fish-like in nature, with rounded features and large, circular eyes. Its mouth is filled with sharp, needle-like fangs. Its legs are large with hard rock scales and end in fins rather than claws. Unlike other Piscine Wyverns, Lavasioth lacks wing-like fins. Instead, it has only a pair of medium-length pectoral fins. It has a long, thick tail to assist in when swimming through the thick magma it resides in.

Lavasioth are very well adapted to live in their habitat. Having a layer of hardened lava, coal, and ore on its skin makes it very durable. They also have the ability to spit lava, which is used to attack prey, or any other monsters that may pose a threat. Lavasioth are powerful swimmers in lava and their speed in swimming through the volcanic rock is matched only by the magma-dwelling Leviathan known as Agnaktor. During the mating season, female Lavasioth will cover themselves in rare volcanic ores in order to attract a mate, giving them a reddish-crimson color.

Lavasioth are extremely territorial and will attack any monster or human that enters its area with ferocity, excluding one of its own kind.
