About this mod

An ever-expanding list of new enemies to enrich the game experience with fresh challenges.

Permissions and credits

offers not only new enemies to include in your games, but also the necessary settings for them to appear in your world and new Raids and Events associated with these enemies.

All enemies created for Monsternomicon have been balanced and tested to bring them as close as possible to the original Valheim experience, but at the same time creating new and unique mechanics to surprise and challenge new and veteran players.

At the moment, Monsternomicon has nine new enemies and a secret boss for the Mistlands biome, eight new enemies, one ally, two secret minibosses and a secret boss for the DeepNorth biome, eight new enemies, two secret minibosses and a secret boss for the AshLands biome, two new enemies and a secret miniboss for the Ocean biome and a new enemy and a secret miniboss assigned to world events. My desire is to continue expanding Monsternomicon with new challenges for these and other biomes.

To make sure there are no issues, it is necessary to remove the old Monsternomicon folder from your BepInEx/config/ folder before installing this update.

Many of you have contacted me to let me know that after the latest Valheim updates some of the creatures created had started to cause problems, so I've set out to fix these problems so that you can continue to enjoy Monsternomicon. Thank you very much for all the feedback.

This update, far from being simply a bug fix, has been a complete overhaul of the creatures present in Monsternomicon, adding new attacks, animations and textures to existing creatures... but there's also much more that I am sure you will soon discover. 

These new changes mean that you will need to delete the old Monsternomicon files to replace them with the new ones (and unfortunately, update any other dependent files) but it strengthens the foundation for further expansion of Monsternomicon with new challenges.

As always, I hope you enjoy Monsternomicon!

  • New textures and game rebalance
All enemies present have been reworked to take advantage of Valheim's latest updates, improving the foundations for future updates... expect to find spiders slowing you down, hungry polar ulvs or huge explosions of fire and tar.

  • Discover two new enemies, two new minibosses and a new boss
From the treacherous Growth of the Ashlands to the huge Wurms of the Mistlands, these new enemies represent a new challenge to the familiar biomes. The ruthless Kraken and the Father of All will be two new threats that together with the new Ashlands Boss will make the gameplay experience even more unique.  

  • Unpleasant surprises after the death of enemies
Drop That has been added as a dependency of Monsternomicon in order to include new interactions after the death of enemies, while making it easier to easily modify the rewards of all Monsternomicon creatures.

  • Take back the Mistlands!
The Forgotten Biomes attachment has been updated to not only repopulate the original Mistlands, but to find new locations in other Biomes.


Sentinel GloomWeaver

"The presence of the swarm watchers is usually only noticeable when their eight legs are at your back, unfortunately it is usually too late by then."

Suffocating GloomWeaver

"Not all GloomWeaver weave their huge webs among the giant trees of the Mistlands, some simply prefer to drown their prey with the venomous poison."

BroodMother GloomWeaver and Brood

"Don't be fooled if you see one of the swarm mothers alone, her dozens of eight-legged offspring are usually close, very close... and all of them are hungry."


"With their divinity ripped away and dragged into the Mistlands of Valheim, the dark elves are mere pale shadows of their former selves... shadows hungry for vengeance and driven by their grief."

Duskseeker Svartálfr

"Able to command at will the very Darkness itself, it is not surprising that they have learned to twist the roots of the World to guide their people to the path of their redemption... starting with those on the Mistlands."

Inexorable Svartálfr

"Considered the personal guard of the Mourning Queen itself, It is said that the sound of their heavy hammers makes the Fulings tremble, whether true or
false, their name certainly pays tribute to these unstoppable creatures."

Moonlit Warden

"As ancient as the very dark forest they protect, these colossal creatures warily guard every little corner of what they consider their sanctuary... Sadly, they consider YOU a threat to their sanctuary."

Moonlit Moth

"These harmless winged creatures scurry through the twisted branches of the trees, dodging the sticky webs as they illuminate the darkness of the Mistlands with their blue wake."

World-devourer Wurm

"Many are the souls who have perished because they discovered too late that one of those huge Mistland roots was really one of these terrible beasts."

The Mourning Queen

"The devoted queen of the Svartfar still mourns the death of her partner. It is said that she is not afraid to exchange the souls of the wretched with Hel herself in exchange for bringing back from the underworld. "

Silver Golem

"The ancient magic hidden in the coveted silver has gifted the stone with life, turning these colossi of rock and metal into the enforcement arm of DeepNorth itself."

Boreal Spirit

"Used by the Dvergar of as guiding beacons in the cold, dark nights, the temperament of these elusive spirits varies as much as the harsh weather in the DeepNorth."

Frozen Corpse

"Even death resists standing still in the icy north, making the gnawed bones of the fallen and the cold metal of rusted weapons creak with the same violence as the blisters."

Icebreaker Lox and Calf

"These huge beasts roam the frozen moors of the DeepNorth on an eternal pilgrimage. Their snow-coloured fur and larger size set them far apart from their Plains kin."


"The story of how the Dvergar arrived in the lands of Valheim is unknown, and like Haldor the trader, they are sparing with words although fortunately they are willing to help a lost traveler on his journey."

Pale-coat Fenring and Ulv

"Their enormous size and strength make even their mountain littermates pale, while the white fur of these ruthless hunters camouflage them in the wintry snowy barren wastelands."

Frost-Brood Serpent

"Giant Frost Serpent are in the habit of spawning on the icy shores of the north. Their offspring may not be as dangerous as an adult Serpent, but they can end up being a tough challenge if enough of them gather."

The One Who is Always Hungry

"Always hungry, never satiated… Run while you still can."

The Forgotten One

"Forgotten by time itself, the icy bones of this tormented soul still roam the barren frozen realms hoping to redeem its fate in combat. "


"If the gods themselves have trouble defeating these colossal beings...what can a mere mortal do against them?"

Fire-breathing Drake

"Natural predators, these huge winged beasts fly over the tortured landscape of the AshLands searching for new treasures with greedy, hungry eyes."

Surtling and Elder Surtling

"Malicious spirits that burn with the fire of wrath. The AshLands have become the perfect habitat for these treacherous beings, who warily guard those fallen gifts from the heavens."

Ash-eater Neck and Tadpole

"The harsh conditions of the AshLands have changed these territorial creatures into their grotesque forms. The little tadpoles may not become a threat, but these had better not alert their parents..."


"Considered a nuisance pest rather than a real threat, these nasty insects fly over the scorched ash-covered plains looking for new victims to turn into breeding nests."


"The Ashlands are capable of claiming a life, but also of giving one to the dark tar itself. "

Burned Bones

"Already more coal than bone, these forgotten fallen warriors wander aimlessly through the desolate hills covered in soot and fire, leaving a furrow in the ash of the ground with their worn weapons."

Swollen Body

"The shores of the Ashlands are littered with shipwrecks and corpses that the Cinderwings use to create their hives - unfortunately, some of these fetid corpses refuse to just lie on the sand."

The Father of All

"Legends speak of an icy mother hidden in the mountains, so it is not so far-fetched to think that there is also a fiery father who watches over his offspring."

The Damned One

"Little more than a hate-fuelled soul and a pile of charred bones, this cursed warrior is said to have claimed vengeance against the Gods themselves."

Hrungnir's Heartburn Scion

"Little is known of these immovable and intimidating masses of lava, obsidian and tar except that they are one of Hrungnir's many bastards. Unfortunately, they retain not only their titanic strength, but also their legendary irascibility."

Storm-herald Wyvern

"Lightning is not the only thing that precedes thunder, but also this hideous hunter that hides in the blackness of storms and illuminates the dark sky with his breath laden with lightning and death."

Drowned Soul

"Not only do fish and treasure lie waiting to be discovered in the ocean depths, but also the vengeful souls of those who fed the ocean itself with their lives, waiting patiently to drag the unwary to their sea graves." 


"Njörðr does not need to punish the fearless sailors who dare to sail the ends of Valheim... the Kraken does it for him."

Storm-devourer Vargr

"Their howls are often mistaken for thunder in the rain, a mistake not often repeated by those few who survive the onslaught of this deadly pack."

The One Who Hunts in the Rain

"Some predators prefer to hunt under the cover of darkness, the more astute ones choose the sound of thunder to drown out the cries of their prey and the rain to hide their tracks."

Recommended Mods

Although it is not strictly necessary I strongly recommend downloading the following mods to enhance your gaming experience:

Forgotten Biomes

The AshLands and the DeepNorth may look empty at the moment but with iAlree's mod you can expand theses biomes (and even others) with landscape decorations, unique points of interest and even new status effects that will make your visit to theses biomes a real challenge.

A custom configuration for Monsternomicon is available for download in the File section.

Terraheim - Weapons Tools and Armor

And what would be the point of visiting the AshLands if there is no reward? Luckily DasSauerkraut has created a whole new set of blazingly deadly weapons to combat all these new enemies using the resources found in this desolate wasteland.

I want to thank neurodr0me, ASharpPen123 and DefendYourBase, creators of the mods requiered for Monsternomicon. Without your work and effort, Monsternomicon would never have been possible. Thank you very much!
