Doppelganger, D&D5e

Challenge your Dungeons & Dragons Crew with Body Snatchers

Found in the Basic Rules.

(Think – Invasion of the Body Snatchers)

Doppelganger Stat Block
Doppelganger Stat Block

A Doppelganger is a devious shapeshifter that take on the appearance of other humanoids, throwing off pursuit or luring victims to their doom with misdirection and disguise.

Doppelgangers are devious shapeshifters that take on the appearance of other humanoids, throwing off pursuit or luring victims to their doom with misdirection and disguise. Few creatures spread fear, suspicion, and deceit better than doppelgangers. Found in every land and culture, they can take on the guise of any individual of any race.

A doppelganger’s adopted form allows it to blend into almost any group or community, but its transformation doesn’t impart languages, mannerisms, memory, or personality. Doppelgangers often follow or capture creatures they intend to impersonate, studying them and probing their minds for secrets.

A doppelganger can read a creature’s surface thoughts, allowing it to glean that creature’s name, desires, and fears, along with a few scattered memories. A doppelganger impersonating a specific creature as part of a long-term plot might keep the double alive and close at hand for weeks, probing the victim’s mind daily to learn how to behave and speak authentically.

Chain Devil, D&D5e

Capture Lost Souls with D&D Hellraisers

Found in the Basic Rules

(Think Hellraiser)

Chain Devil Stat Block
Chain Devil Stat Block

This ominous fiend wears chains like a shroud. Driving lesser creatures before it with its fearsome gaze, a chain devil animates the chains that cover its body as well as inanimate chains nearby, which sprout hooks, blades, and spikes to eviscerate enemies.

Chain devils act as sadistic jailers and torturers in the infernal realms, relishing pain and living to inflict it on others. They are called on to torment mortal souls trapped in the Nine Hells, inflicting their sadistic fury on the horrid lemures in which those souls manifest.

Elder Oblex, D&D5e

A Science Fiction nod for High Fantasy

Found in Mordenkainen’s Tome of Foes

(Think – The Blob)

Elder Oblex Stat Block
Elder Oblex Stat Block

By experimenting on the slimes, jellies, and puddings that infest the depths of the Underdark, mind flayers created a special breed of ooze, the oblex — a slime capable of assaulting the minds of other creatures. Cunning hunters, these pools of jelly stalk prey, searching for the memories they so desperately crave.

When oblexes feed on those thoughts, sometimes killing their victims, they can form weird copies of their prey, which help them to harvest even more victims for their dark masters.

Oblexes feed on thoughts and memories. The sharper the mind, the better the meal, so oblexes hunt obviously intelligent targets such as wizards and other spellcasters. When suitable fare comes within reach, an oblex draws its body up to engulf its victim. As it withdraws, it plunders the creature’s mind, leaving its prey befuddled and confused. An oblex doesn’t require sleep.

Sibriex, D&D5e

Make your D&D Players Wish for Death

Found in Mordenkainen’s Tome of Foes

(Think Lovecraftian Horror)

SIbriex Stat Block
Sibriex Stat Block

Incarnations of chaos and evil, demons display endless variation in appearance and in how they go about wreaking havoc across the multiverse.

Thought to be as old as the Abyss itself, sibriexes haunt remote parts of the plane, where they use their vile abilities to breed new horrors and apprehend forbidden lore. Rivulets of blood and bile cascade from a sibriex’s body. Where these noxious fluids hit the ground, the landscape becomes polluted.

Sibriexes have spent eons amassing information from across the planes, hoarding knowledge for when it might be useful. Such is their incredible intellect that many seek them out, including demon lords.

Some sibriexes act as advisors and oracles, manipulating demons into serving their ends, while other sibriexes cling to their secrets, parceling out lore only when doing so would advance their plans.

Brain in a Jar, D&D5e

A Unique choice for Brainy Dungeon Masters

Found in Icewind Dale: Rime of the Frostmaiden

(Think – The Man With Two Brains)

Brain in a Jar
Brain in a Jar Stat Block

Through rituals combining alchemy, necromancy, and grim surgical precision, the brain of a mortal being is encased in a glass jar filled with preserving fluids and the liquefied goop of their body’s flesh. The transformation renders the brain ageless and imbues it with psionic power so that it can spend eternity plotting and executing its desires.

A brain in a jar can speak without vocal cords, psionically projecting its disembodied voice outward for all to hear. It enjoys conversation so much that it is prone to talking for hours on end, sometimes to itself if there are no others with whom it can speak. It also likes to think out loud and reflect on the events and decisions that led to its great transformation.

A living brain floats in a jar of thick solution, pulsating as it reacts to its surroundings. Some brains have been known to thump against the walls of their containers when excited or vexed. A jar’s metal casing might be rusty but serviceable, or an elegantly wrought masterwork, depending on its creator.

Still, other brains desire nothing more than to regain a body. This might be the brain’s original body, another frame they covet, or some more elaborate design of their own diabolical creation. While disembodied, a brain in a jar weighs roughly 125 pounds.

Gibbering Mouther, D&D5e

Creep your players out with this D&D “THING”

Found in the Basic Rules

(Think – The Thing)

Gibbering Mouther Stat Block
Gibbering Mouther Stat Block

Of all the terrors created by foul sorcery, gibbering mouthers are among the most wicked and depraved. This creature is the composite eyes, mouths, and liquefied matter of its former victims. Driven to insanity by the destruction of their bodies and absorption into the mouther, those victims gibber incoherent madness, forced to consume everything in reach.

The gibbering mouther’s body is an amorphous mass of mouths and eyes that propels itself by oozing forward, fastening several mouths to the ground, and pulling its bulk behind. Though it moves slowly, it swims through water, mud, and quicksand with ease.

When a gibbering mouther senses prey, its mouths begin to murmur and chatter, each with a different voice: deep or shrill, wailing or ululating, crying out in agony or ecstasy.

This cacophonous gibbering overcomes the senses of any creature that hears it, causing most to flee in terror. Others are overcome with madness or stand paralyzed, fixated on the horrific creature as it oozes forward to consume them.

Zombie Clot, D&D5e

Build a sense of dread with The Living Dead

Found in Van Richten’s Guide to Ravenloft

(Think – World War Z)

Zombie Clot Stat Block
Zombie Clot Stat Block

Among the undead, a lone zombie ranks far from the most menacing. The horror of the shambling dead lies not in their individual menace, though, but in their numbers, their persistence, and their disregard for their well-being. A throng of zombies will douse a forest fire with their ashes or march into a dragon’s maw until the monster chokes.

In the course of their relentless marches, zombies might suffer all manner of trauma, potentially reducing them to masses of crawling limbs (see a swarm of zombie limbs), infecting them with terrible diseases (see zombie plague spreader), or crushing an entire horde into a single, rotting titan.

Nothic, D&D5e

Immediate option for Dungeon Masters to Challenge Player Characters

Found in the Basic Rules

(Think – Stranger Things)

Nothic Stat Block
Nothic Stat Block

A nothic is a monstrous creature with terrible talons and a single great eye. When driven to violence, it uses its horrific gaze to rot the flesh from its enemies’ bones.

A baleful eye peers out from the darkness, its gleam hinting at a weird intelligence and unnerving malevolence. Most times, a nothic is content to watch, weighing and assessing the creatures it encounters. When driven to violence, it uses its horrific gaze to rot the flesh from its enemies’ bones.

Rather than gaining the godlike supremacy they crave, some wizards who devote their lives to unearthing arcane secrets are reduced to creeping, tormented monsters by a dark curse left behind by Vecna, a powerful lich who, in some worlds, has transcended his undead existence to become a god of secrets.

Nothics retain no awareness of their former selves, skulking amid the shadows and haunting places rich in magical knowledge, drawn by memories and impulses they can’t quite understand.

Nothics possess a strange magical insight that allows them to extract knowledge from other creatures. This grants them a unique understanding of secret and forbidden lore, which they share for a price. A nothic covets magic items, greedily accepting such gifts from creatures that seek out its knowledge.

Flesh Golem, D&D5e

The Best D&D Monsters from a Horror Classic

Found in the Basic Rules

(Think – Frankenstein)

Flesh Golem Stat Block
Flesh Golem Stat Block

A flesh golem is a grisly assortment of humanoid body parts stitched and bolted together into a muscled brute imbued with formidable strength. Powerful enchantments protect it, deflecting spells and all but the most potent weapons.

The construction of a golem begins with the building of its body, requiring great command of the craft of sculpting, stonecutting, ironworking, or surgery. Sometimes a golem’s creator is the master of the art, but often the individual who desires a golem must enlist master artisans to do the work.

After constructing the body from clay, flesh, iron, or stone, the golem’s creator infuses it with a spirit from the Elemental Plane of Earth. This tiny spark of life has no memory, personality, or history. It is simply the impetus to move and obey. This process binds the spirit to the artificial body and subjects it to the will of the golem’s creator.

Golems can guard sacred sites, tombs, and treasure vaults long after the deaths of their creators. This allows them to carrying out their appointed tasks for all eternity while brushing off physical damage and ignoring all but the most potent spells.

Flesh Golems can be created with a special amulet or another item that allows the possessor of the item to control the golem. Golems whose creators are long dead can thus be harnessed to serve a new master.

Oni, D&D5e

Bend Dreams and Reality with This D&D Bogeyman

Found in the Basic Rules

(Think – The Babadook)

Oni Stat Block
Oni Stat Block

In nursery rhymes, oni are fearsome bogeymen that haunt the nightmares of children and adults alike, but they’re real and HUNGRY. They find human babies especially delicious. Oni have blue or green skin, dark hair, and a pair of short ivory horns on their foreheads. Their eyes are dark with strikingly white pupils, and their teeth and claws are jet black.

Night Haunters. By the light of day, an oni hides its true form with magic, gaining the trust of those it intends to betray when darkness descends. These creatures can change their size as well as their shape, appearing as humanoids as they pass through towns, pretending to be travelers, woodcutters, or frontier folk. In such a form, an oni takes stock of the selection of humanoids in a settlement and devises ways to abduct and devour some of them.

Magical Ogres. Oni are sometimes called ogre mages because of their innate magical ability. Though they are only distantly related to true ogres, they share the habit of joining forces with other evil creatures. An oni serves a master if doing so proves lucrative or provides it with a luxurious, well-defended home. Oni covets magic, and they work for evil wizards and hags in exchange for useful magic items.
