Expanded Cryptids

Cryptids

By its very nature, the Material Plane is a realm full of mysterious creatures and legends. Despite centuries or even millenia of research and study, there are still many unknowns associated with the Material Plane an its inhabitants, some that defy all explanation.

One of these mysteries are cryptids whose very existence is often debated. The only information of these creatures are from various accounts and legends of varying degrees of credibility. Attempts to search out the true, scientific and magical, have failed to fully understand these creatures.

However, such stories and accounts are often the motivation more many adventurers seeking a true challenge to attempt to uncover the truth behind such creatures.

Woodwalker

The most notorious of all cryptids is the elusive woodwalker. Most civilizations to some degree have recorded mysterious encounters with a enormous humanoid creature. Although many accounts vary from one another, such accounts seem to suggest the woodwalker is a large humanoid that is covered in a thick coat of fur, or even feathers. Some suggest these creatures are merely a hoax or magical illusion while others seem to believe it is a subspecies of giant or yeti.

Territorial Ambusher

Although most accounts just describe a potential sighting, a select few accounts that describes actual encounters with this creature. Such accounts seems to suggest it its an ambush predator relying on the element of surprise. Despite its large size, these creature is surprisingly fast and elusive seemingly vanishing into the shadows in the blink of an eye. However, this elusiveness seems to make it an extremely dangerous entity. This creature has been reported to be quite hostile, stealthily stalking individuals that wander into its territory. Although most accounts seem to suggest woodwalkers are solitary creature, some select few accounts seem to suggest that some may exist in small communities.

Supernatural Abilities

It seems to prefer to take out its prey one at a time leaping out of the shadows and ripping its foes limb from limb before fleeing back to the shadows. This creature seems to have a supernatural resilience easily recovering from the harshest of wounds and debilitating effects. Its thick fur seems to dampen the blows of most conventional forms of weaponry and its sharp claws are powerful enough to shred all by the hardiest of armors. However, it most terrifying ability seems to be the gaze of such of creature that seems to fill its opponent with an overwhelming sense of dread that locks one's very muscles.

Fear of Fire

Thankfully, some of these accounts seems to suggest it has an aversion of fire. It seems that exposure to fire poisons or debilitates this creature causing it to temporarily negate some up the woodwalker's defenses. Utilizing such magic or weaponry should prove advantageous when attacked by a woodwalker; however, this would also cause the woodwalker to flee. Once it flees, its nigh impossible to track where it flees off to thanks to its cryptic nature.

Night Walker Tactics

The woodwalker is an extremely elusive but territorial creature. It tends to patrol a large swathe of territory typically around 100 miles across covering a lot of ground and avoiding civilization. Thanks to its keen senses and vision, the woodwalker is able to detect and pinpoint the presence of a humanoid within 6 miles of it.

Vigilant Stalker

Upon detecting their presence, the woodwalker begins to stalk and track these individuals for hours and even days watching and learning of their habits and behavior. Most of the time, the woodwalker will not become aggressive and is content to leave them be. However, it will become hostile if the individuals do not leave its territory in an timely manner, if they further encroach on its realm, possibly in search of it, or if its feeling particularly hungry.

Scare Tactics

When dealing with humanoid prey, it prefers an elusive chase rather than a direct attack that it tends to do with its standard prey. Since most humanoids tend to rarely travel alone, the woodwalker will resort to spooking them in an attempt to cause them to flee. It will resort to making unearthly screeches or causing noise in the underbrush to unnerve the intruders. Such tactics will cause its target to either flee or follow the source of the sound.

The Chase

If it flees, it continues to skulk and spook its target leading it out of its territory. If its prey chooses to pursue it, it leads them deeper into its territory where it has the advantage. As an intelligent creature, the woodwalker has learned to craft primitive traps to catch prey as well as defend itself. Using a series of unnatural shrieks and false trails, it attempts to deceive its prey into believing there are multiple entities causing them to split up. Using its supernatural agility and climbing ability, it is able to cover much ground to stalk its intruder with incredible speed.

Ambush Combatant

Using the cover of shadow and plant life, it is able to sneak up and surprising its prey. Upon appearance, it locks its gaze on that creature causing it to tense up in fear preventing its escape or the ability to call for help. Once its prey is incapacitated, the woodwalker makes quick work of its prey using its sheer strength to bludgeon its foe with its powerful fists in a matter of seconds. If the creature survives its initial onslaught (typically after 1d4 rounds or if its prey acquires assistance), the woodwalker will rarely engage a creature for too long before skulking back into the shadows. Although its bulk and endurance allows it to endure a lot of punishment, it prefers to fight on its own terms and can patiently wait for its foe to let its guard down to deal the finishing blow.

Upon killing a creature, it will rarely feast on its prey until all of its opponents are slain but will use their corpses to taunt and spur the survivors to make foolish and rash actions to engage the beast on its own terms.

Frost Walker

Although the majority of woodwalker accounts seem to be in regions with dense forests; some accounts rumor of another species that resides in arctic regions. This creatures seems to be much more elusive, but more dangerous than its forest-dwelling kin.

Icy Gaze.

It is rumored frostwalkers only appear in blizzards and large snowstorms where they seems to appear out the storm as wraiths towards their prey. A single gaze from such a creature has been known to transform a creature into a statue of ice. It is believed such a gaze is used primarily as a defense mechanism and not a means of incapacitating prey as they seem to prefer fresh blood rather than ice. You can replace its paralyzing gaze with its petrifying gaze.

Blizzard Marauders

They have been rumored to attack settlements under the cover of a blizzard taking kidnapping individuals from their very homesteads dragging them back to their lair to eat them. The only sign of their presence after a blizzard are the missing individuals and the shattered and melting shards of ice of anyone that attempted to stand in its way. Unfortunately, because of their appearance and abilities, they are often confused to be yetis who often are the subject of retaliation for such attacks. You can substitute its skulker ability with snow stalker

Bonewalker

The bonewalker is the deadliest relative of the woodwalker. It shares a similar appearance to the woodwalker but seems to be slightly larger and is adorned with an array of skulls, spines, and ribs that are fashioned into primitive armor and weapons.

Savage Hunter

Whereas the woodwalker is largely territorial unless hungry, the bonewalker actively searhes for humanoids in its territory. Most of the time it hunts for sustenance, but will hunt for sport, especially when it comes to humanoids.

Bone Collector

It prizes itself on its collection of bones from each successful hunt and fashions it into primative and brutal weapons. It territory is often decorated with totems and traps forged with the bones of its enemies. However, it employs a brutal tactic to retrieve its bones, by ripping the spine from the very body of its living prey.

The bone walker can substitute its claw attacks for a bone claw attack in its multiattack. It can substitute two bone claw attacks for a spine taker attacker if the conditions are met


Spike Trap

Creatures within a 10ft. radius of its designated spot, creatures must succeed a DC 15 Dexterity saving throw or fall 30ft. into the trap. Upon a failed saving throw, creatures takes 7d6 piercing damage and is restrained. It must take an action to remove itself from from the spikes with a DC 15 saving throw. Upon a failed check, it take 7(2d6) piercing damage. On a successful saving throw, it takes half damage and is not restrained.

Snare Trap

Creatures within a 10ft. radius of its designated spot, creatures must succeed a DC 15 Strength saving throw. On a failed saving throw, creatures are restrained and pulled 30ft. into the air ensnared within a net. While trapped, creatures take 10(4d4) piercing damage at the start of each of its turns.

This trap can be discovered with a DC 15 Wisdom (Perception) check to notice something is amiss. If they are searching fro traps, they must succeed a DC 15 Intelligence (Investigation) check to discover the trap

Traps

The walker employs a number of traps in its territory that it uses to hunt for prey as well as defend against intruders. It takes the walker about 1 day to craft and place 3 (1d4) traps. The walker knows the locations of each of these traps.

For the regional variants of the woodwalker, you can substitute the traps to include the appropriate materials. For example a log trap may be an ice trap for a frostwalker.

Spike Trap

The walker tend to lure unsuspecting prey or intruders into its spike trap by luring them to its location via chasing or spooking them. By its design, the spike trap appears to be a pile of dead leaf or underbrush that seems to cover a 30ft. pit lined with barbed wooden or bone spikes. These barbs are designed to cause more blood loss whenever a creature attempts to pull itself free from the trap.

(The additional damage from the 30ft. fall is already calculated into the trap's initial damage)

Snare Trap

The snare trap is another trap utilized by the walker. It often appearance as a mass of barbed vines lying dormant on the ground that encases the target into a barbed net and suspends its 30ft. in the air. The nature of this trap causes the netting to constrict onto the target forcing the barbs into into a creatures body.

However, up detection, this trap can be disarmed by severing the snare line causing the trap to activate prematurely.

Log Trap

The log trap is probably the walkers most potent trap as it is the hardest to perceive. It often resembles a normal tree branch. However, if a creature triggers a tripwire normal fashions by thick vines, this limb becomes dislodged landing on unsuspecting prey below.

Cruorhound

The cruorhound is a decrepit beast that is rumored to resemble the abominable cross of a lizard, hound, and a bat. Despite, it small size, this creature has been rumored to be extremely dangerous hunting in small packs and draining its victims of their blood.

Vile Creations

Although the origins of many cryptids are a mystery, many have various theories of its origin. Most scholars seems to agree that the cruorhound is not a natural creature by any means thanks to its supernatual abilities.

Some scholars believe that they are a failed creation of powerful undead or necromancers that attempt to merge the qualities of undead and the living to create an creature that was resistant to many of the shortcomings of conventional undead. Some suggest that these creatures suffer from a more primitive form of vampirism that takes its form only in beasts. Others seem to believe that these creatures are the result of a fallout from a magical disaster or experiment gone wrong that warped nearby wildlife.

Regardless of its origin, these cryptids can proves to be quite dangerous by themselves and are near always lethal as a pack.

Shadow Stalker

Based on all accounts, cruorhounds seems to appear only at night seeming appearing out of the shadow like a specter. Its ability to blend into the darkness makes it extremely hard to perceive and target with attacks. However, is does has a disdain to sunlight causing it to immediately flee and radiant magic does seem to temporarily hinder some of its natural resiliency.

Blood Scent

The cruorhound's diet consists primarily of blood. It seems to possess a keen sense of smell and is able to pinpoint the presence of even the most hidden of all hidden creatures.

All encounters with such creatures seem to suggest that it drains its victims dry of its life force leaving it as a withered husk. These accounts also seem to suggest it devouring blood grants makes these beasts much more powerful. By it self, the cruorhound displays extraordinary resilience as its seems to be largely unharmed by conventional weapons and has superior regenerative abilities that quickly heals any wounds it may possess.

However as drains the life force from its prey, it regenerative nature seems to be heightneed granting it supernatural speed and attacks for a short period of time.

Cruorhound Tactics

Just like other cryptids, the cruorhound is quite elusive coming out only at night. Any encounters with such a creature often end up as its prey as the only accounts seem to be of lucky survivors or the lucky observer. However, the cruorhound activity is often hinted by the presence of withered corpse of livestock or even humanoids found in the wilderness outside settlements.

Pack Hunters

Despite the variation of accounts, it seems to be a consistent assumption that cruorhounds hunt in large pack typically of consisting of 11(2d10) members. Despite the large size of such packs, they tend to hunt in small subgroups typically of 3 (1d4) members at a time only coming together when attacking numerous prey.

Cruorhound packs seem to be much more sophisticated than their beastil equivalents as they seem to be able to empower one another especially in the presence of blood. Such abilities seem to suggest that they are able to teleport through the shadow towards one another, or even heal one of their fellow allies.

Fear of Dawn

Although the cruorhound is quite lethal in its own right, it does seem to possess a strong sense of self preservation. When overwhelmed by its prey, it is not afraid to slip unseen into the shadows to flee and recover from its wounds. Once fully recovered, the cruorhound regroups with allies usually returns to finish off its foe now in greater numbers.

Only in the presence of sunlight or radiant energy will the cruorhound immediately flee never to return to face that creature as it is deathly afraid of sunlight. However, it seems to only show this fear towards sunlight and radiant magic as other sources of bright light do not seem to bother it to any degree.

Rat King

Of all the rumored urban myths, the rat king is probably the most horrifying. Rats in general quite common in most cities; however, rumors of the rat king are seem to only exist in the sewers of the largest of cities.

Abominable Vermin

The simplest definition of the rat king is that it is a monstrous amalgamation of hundreds of rats merged together into a large hulking form. Some of the more tame accounts, seem to describe a colossal rat with a writhing body hide of rats. More grotesque accounts describe a bulbous mass of flesh with various rat and tails protruding from its form.

Its body its made with wrinkled folds of merged flesh that seems to writhe and move as if rats are swimming beneath its skin. Upon being heavily wounded, its body seems to spill out giant rats and it has a strange ability to absorb nearby rats to rebuild its form. Its limbs for arm made froom dozens of gnawing rats teeth and writhing tails. To make things worse, the rat king seems to have the strange ability to temporarily transform into a swarm of rats, slipping through the smallest of cracks.

Vile Origins

It is not entirely understood how these rats fused into this form. Some believe that the continual intake of refuse and waste resulted in horrific mutations they merged these creatures together. Other scholars believe that rat kings are made when they consume the corpses of dead forged by necromantic magics. Upon consuming such vile magics, these rats underwent horrible transformations as its absorbed more rats into its bulbous form.

The final theory seems to suggest the rat king is not actually a singular creature but the creation of singular hive-mind complex. This theory derives much of its proof from the fact that the rat king seems to disperse into multiple swarms upon the apparent destruction of its fused form.

Sewer Lurker

The first sign to suggest a rat king's presence is the uncanny presence of rats in the vicinity. These rats act with an unusual and seemingly unified intelligence acting under the accord of the rat king. It is believed that this monstrosity is able to control the minds of these rats and is able to perceive through its thralls sense's. This makes finding the location of the rat king is nigh impossible as it resides in the deepest often forgotten corridors of the sewer system which is constantly surveyed by its minions.

Rat King Tactics

The rat king is at its most powerful while it resides in the sewer and never leaves its home for any reason. The rat king is a gluttonous creature sending its vermin swarms to kill and bring food to it. Intrepid adventurers searching for it must traverse labyrinthine sewer tunnels or catacombs while harassed by waves of rats under the control of this creature.

Living Vermintide

Battling a rat king is a grueling task, for if one manages to endure its horrid stench and incessant rat swarms, one must attempt to account for hide of writhing rat teeth. One of its most dangerous features is its ability to engulf its prey into its form subjecting to an infinite barrage as the rats inside its form eats the creature alive. As one continues to wear down its form, the rat king seemingly begins to bleed rats as more vermin drops from its form to harass its attackers.

However, upon killing a rat king, the threat does not end, instead, the rat king seems to dissolve into multiple rat swarms which completely disperse upon being destroyed. Such a strange demise leads to the question of the true nature of a rat king and whetther it can truly be killed.
