Aberrations and cosmic horrors
Crimson slime covers this ungainly creature. Its tiny black eyes sit in an abnormally large head, and dozens of sharp teeth fill its small mouth. Its limbs end in large, grasping claws that look strong enough to crush the life out of a bear._ **...
_With webbed claws, bulbous eyes, and two nostril-slits that ooze an oily black substance, the creature is not quite hideous—but it might be, if most of it wasn’t concealed by a thick coating of muck and mud._ **Bathing Uglies.** When a bagienni...
_An asasonbosam is a hirsute hulk with bulging, bloodshot eyes, often perched high in a tree and ready to seize unwary passersby with talons like rusty hooks._ **Iron Hooks and Fangs.** They resemble hairy ogres from the waist up, but with muscu...
_Long, simian arms snake through the trees like furred serpents, dangling from a shaggy, striped ape in the leafy canopy above and trying to snare those below._ An arboreal grappler is a malformed creation of the gods, a primate whose legs warpe...
_This collection of hundreds of eyes floats along, trailing ganglia and dripping caustic fluid that sizzles when it hits the ground._ **Failed Experiment.** An oculo swarm results from an experiment to create a live scrying sensor that went poor...
_This horrible gigantic crimson leech slithers upright on four muscular tentacles, each 30 feet long. At the top of its writhing trunk, a great lidless eye glows with baleful orange light, surrounded by quivering, feathered antennae fully 5 feet l...
_This horrid creature looks like an enormous flying jellyfish, with long, wicked tusks curving from its gaping mouth and tentacle-whiskers trailing behind it._ **Alchemical Flotation.** These aerial jellyfish waft through the air like balloons, ...
_Mordant snares were created by war mages of ancient times. Each resembles an immense, dark gray, 11-armed starfish weighing eight tons, and yet a mordant snare is never obvious. Instead, it controls a few humanoids shuffling about aimlessly, thei...
_Watching with many rows of eyes, this mantis creature strikes with slashing claws and recurved barbs dripping with venom._ **Dimensional Travelers.** The clandestine xhkarsh are beings from another cosmic cycle. Their devices and armor are inco...
_Tiny wisps of grayish smoke ooze from the slate-colored coat of this leonine beast._ **Ethereal Lions.** The elusive mngwa (MING-wah; “the strange ones”) are the offspring of a sentient feline beast from the Ethereal Plane that mated with a lio...

Tiny Aberration, CR 1/4. From Tome of Beasts.
_This tiny monstrosity combines the worst elements of a dead frog and a rotting fish. Its slimy, scaly, vaguely humanoid form has three clawed arms arranged radially about its body. Its slimy green bat‑like wings seem too small to work, yet it fli...
_Writhing black tendrils stretch from this indistinct orb of pure shadow. The faintest flicker of something green, like an eye, appears for a moment in the center of the globe and then fades to black again._ **Called from Darkness.** Voidlings a...
_This enormous pig is as large as an ox, and its mouth bristles with mismatched tusks. Its body is a lopsided mass of tumorous flesh that gives way to eyes and vestigial mouths, and long tentacles trail from its sides._ From time to time, a brea...
_These hideous, reeking creatures resemble toothless, cadaverous hags, their large eyes glowing with unearthly green light, and their fingers tipped with ragged claws._ **Twisted Nymphs.** Qwyllion (the name means “polluter” in Old Elvish) are n...
_A bit of catchy, repetitive music emanates from nowhere, drifting and moving as if dancing in the empty air._ **Born from Drama.** Incredibly moving arias, passionate performances, and ditties that drive you mad are often the product of ostinat...
_These human-sized parasites resemble ghostly centipedes surrounded in erratic violet radiance. Their flesh is translucent and their jaws are crystalline—they are clearly creatures of strange planes indeed._ **Destiny Destroyers.** Fate eaters i...
Medium Aberration, CR 9. From Tome of Beasts.
_These twitching balls of tentacles surround an inhuman face dominated by a squid-like beak._ **Servants of the Void.** The dorreqi are servants to ancient horrors of the void and realms beyond human understanding. They are guardians and sentrie...
_A chelicerae resembles a massive spider perched on tall, stilted legs. Most often, the disheveled body of a robed arcanist swings from its clenched mandibles._ **Feed on Spellcasters.** These massive arachnids are largely confined to the great ...
_A shoggoth is an intelligent, gelatinous blob that can reshape itself at will. Created by an elder race as servants, the shoggoths rebelled long ago and slew their masters without pity. Since that time, they’ve lived in isolated or desolate regio...
