Putrid haunts are walking corpses who died while lost in swamps, and become infused with their own resentful fury and merge with the swamp. Mud and moss fuse to the body, filling its blood vessels and undead leeches rapidly replicate along the skin and within the systems. Where one haunt occurs, others soon follow, and packs of them may gather together to lie under the muck until another person comes close enough to spark their fury.

Possessed pillars are an ancient creation. The original ones look like animal headed humanoids, representatives of ancient gods or demonic figures. The most common ones from these older civilizations have jackal or ibis heads, though baboons, crocodiles, elephants, and hawks were also used. Other possessed pillars have been made in other designs, some even eschewing humanoid form entirely. One universal aspect of these constructs however is their ability to steal weapons from those who attack them, the weapon sticking to the pillar's body to disarm and help neutralize intruders.

Pomberos are squat fey figures who dwell in shadowy wildernesses. With long limbs and thick hair on the back of their hands and tops of their feet, and a face too wide for their head, they look just unusual enough that they tend to stand out on the rare occasion they're seen. They are primarily tricksters, who shun bright light and enjoy creeping into places they don't belong to steal interesting objects.

A living piece of music, ostinatos are born from extreme emotions and live by implanting themselves in a person's mind and feeding off of the energy and personality of other creatures. When they inhabit a host they manifest as a bit of repetitive music stuck in the host's mind, constantly mildly distracting but occasionally working as an inspiration or muse for musicians.

A festering slime bubbling with rank marsh gas and acidic secretions, corrupting oozes dwell in out of the way corners feeding on whatever flesh they can get. Despite being functionally mindless, they are drawn toward certain unholy creatures, easily directed by fiends, in particular heralds of darkness or blood who often can use them as foot soldiers. Most unnerving about them is their tendency to form into a rough humanoid shape, shambling forward on two legs, though impossible to mistake for a person.

Also known as mockmires, oozasis are massive oozes that are far more intelligent than is usually associated with such creatures. Crystal clear, they mimic a safe watering hole, creating an illusion of a healthy and safe place to rest while the oozasis decides if they are well suited for its inscrutable purposes. Those who drink of its waters or eat plants watered by it are susceptible to demands it makes, it can telepathically force a mission upon them for cryptic reasons.

How does a floating swarm of independent eyes come about? Obviously forbidden magical experimentation, this is no natural evolution. Or even an unnatural evolution. Attempts to create a living scrying sensor did not work as intended, the eyes becoming self-aware and fiercely dedicated to survival, putting them at odds with their creators who expected a disposable tool. With just that oculo swarms would probably be rare and stay well hidden, but in addition they are able to rip eyes from almost any living creature and add them to their collective consciousness.

Once other humanoids, noctiny are corrupted by fell power and transformed. While they superficially resemble the people they were before, the transformation they submit to for power washes away much of their previous identity, leaving them a much more homogeneous group. Sallow and gaunt, with sickly gray skin even before they smear it with ash and dust to wash away all living color.

Nkosi are a type of bestial humanoids, with aspects of lions to their form. Eyes, tail, fur, and teeth. They do not merely have lion aspects however, being born with the innate ability to shapeshift into a lion's form, though most do not have the strength or size of a true lion. Their scouts and warriors favor curved blades such as the mambele, and mix weapon strikes with snapping lunges from their large, curved fangs.

Nightgarm are unholy creatures created by a foul ritual performed over a pregnant warg. The cubs from such a ritual are nearly always stillborn, but rarely the ritual instead sticks and the newly born is a nightgarm. Always female, they are dedicated to harassing and destroying the servants of the gods, and will have their spawn infiltrate settlements to bring them down.

Nichny are deeply xenophobic and aggressively carnivorous fey beings that live in primeval forests and dispense luck, both good and bad. Despite their intense desire to be left alone, they are often sought out for the luck they can provide and for their oracular powers. Legend holds that a nichny bound in gold and orichalcum cannot escape, and can be forced to answer questions.

These almost universally female faerie drakes are extremely elegant and majestic, plumed with feather-like hairs and glittering, multicolored scales. They are capable of taking on a humanoid form, which is consistent and specific to each naina, and will often be either an elderly human woman or a young elvish woman, though some naina have different, similarly distinct appearances. Their reputation as cruel tricksters and manipulators makes others hesitant to work with them, though they are often quite old and have a lot of stored knowledge and wisdom they can be convinced or tricked into sharing.

The myling was first made a while back as a backer request, but now that I've reached this point in the book itself I've gone back and edited those stat blocks with more experience and under my belt. The differences aren't too extreme, mostly just formatting and adjustments. Myling are small undead who are born from those that died of exposure and were never given a proper burial or other final rest.

Each version of these games has a different sentient mushroom people, so each game will therefore need distinct fluff on how the deathcap shows up in that game's setting. Generically, deathcaps are mostly peaceful despite their extremely toxic spores they produce. They will use their spores to defend themselves and where they live, but will usually try to find some kind of powerful or organized ally to ensure they are secure and safe.

These mummies are created with wrappings soaked in strong venom, infused with magic and divine power to ensure it never loses its potency no matter how much time passes, and charged with acting as agents of vengeance for their patron. This poison carries a divine curse with it, inflicting those the mummy attacks and latching onto the soul, making it highly difficult to remove.

Moss lurkers look like a troll the size of a gnome, with a personality more toward brutal bullies. Despite their small size, they are often fans of large, heavy weapons, often wielding blades that seem too large for their bodies rather than their natural claws or something more appropriately sized. They also have a fondness for dropping heavy rocks onto enemies, and train to improve their accuracy with such threats, as well as finding ideal locations for such tactics in their environments.

Morphoi are shape-shifting plant creatures that can take the form of nearly any creature. In their natural form, they appear as 5 to 6 foot tall androgynous beings with blue skin, and two eyes on each the front and back of their head, and no other features. They have a dark red sap in place of blood. They don't need to eat, gathering nutrients from sunlight and water, but while disguised as humanoids or other creatures they will consume small amounts of food to maintain their cover.

A gigantic, dark gray, 11 armed starfish, the mordant snare is an artificially created bioweapon designed to eliminate entire villages at a time. They use spiked filaments within their many arms to inject acid within the bodies of living creatures, dissolving the internal structures then pouring additional filaments and acid within to puppet the corpse about, using a crowd of them to lure in additional prey.

Beautiful and elaborate suits of armor animated with shadow magic and fueled by a flickering blue flame that is both freezing cold and burning hot to the touch, these constructs are more decoration that guardian, being fairly fragile for their cost. They are inordinately expensive, both in terms of material construction and magical animation, far beyond their combat prowess is worth.

Mngwa are elusive cat-like creatures with high intelligence and the ability to speak with other felines. They are strong and cunning, picking hunting grounds among rocky and terrain and foggy weather to better suit their hunting skills. The strongest mngwa will recruit other great cats into prides to aid in hunting, and sometimes even cat-like humanoids. Inspired by the Tome of Beasts 1.

A pair of fey beings for this update. Mirager Fey creatures of deserts and oasis, miragers in their natural form appear to be roughly humanoid sand figures, though few see them in this form. They typically remain disguised as humanoids, taking on attractive appearances clad in veils and flowing robes to accentuate their beauty and lower the guard of those who find them.
