There are some really scary monsters in The Witcher 3. These ones are the strongest in the game.
In the world of The Witcher 3, you’ll face many strong enemies as you travel the lands. The Witcher games are hard because you have to beat enemies that get harder and harder, like wolves, palace guards, and monsters from your dreams.
It’s true that you can always level up or bring new gear to a tough battle to make things easier, but some enemies just seem too tough no matter what. Besides some boss fights, there are other groups of enemies that will be hard to beat, no matter how prepared or high-leveled you are. Here is a list of them.
Basilisks

It looks like a chicken crossed with a dragon, and basilisks are big Draconids. They like to jump and claw from above, and when they want to attack, they like to spread their wings wide.
The best ways to attack them are with dancing star bombs and Igni. While rolling is the best way to avoid their hits.
Rotfiends

On their own, Rotfiends are not that hard to beat. On the other hand, they rarely show up by themselves. Instead, they usually fight in groups with Drowners.
They like to leap and swing their arms around. The blast that happens when you beat them is even more dangerous. People nearby can be hurt by the blast, but you have to be aware of your surroundings whenever you fight a Rotfiend.
Elementals

They come in three different types. Fire, Ice, and Earth. It looks like each form is big and rocky, and it can take a lot of damage. Quen is the best way to fight them because it spreads out the damage a bit.
The only fast ways to hurt them are with elemental oil and dimeritium bombs. The fire creature is a bit harder, but Northern Wind bombs and putting out its fire can help.
Giant Centipedes

Blood and Wine is the first game to have giant centipedes. They are armored beings that like to move quickly, dig holes in the ground, and then attack.
The best way to fight them is to slow them down with Yrden and hit them on the bottom when they stand up. They usually fight in groups, which can be annoying when you run into them.
Leshen / Leshy

Most likely, the most scary and creepy monsters in The Witcher 3 are the Leshen. Their size is intimidating, and they look very scary. Most of the time, you can find them walking around in woods at night.
They like to dig into the ground on their own and send out roots to attack from below. But they generally have help, like dogs and crows that can confuse you. It’s already hard enough to beat them, but they can also turn into fog. This can’t happen with a Moon Dust bomb, and Igni can help you do more damage to them faster.
Cyclopes

Cyclopes are a rare enemy in The Witcher 3. Just remember that “cyclope” means “two clones.” They like to swing their arms, jump into the air, and charge at you. They are huge and strong.
They can take a lot, which makes fights with them hard. To move things along faster, you must corner them. You can do this by rolling or using Axii to get behind them and hit them where they’re weaker. If not, the fight might last a long time and be very painful.
Werewolves

There are a lot of werewolves in magical books, so it’s not a wonder that you meet some in The Witcher 3. Their speed and strength are so great that they are very hard to beat. The thing that makes them so hard, though, is that they can fix themselves. It’s hard to take down one of these beasts because they heal so fast.
The one that roams outside the Ancient Oak is especially like this. This is one of the hardest things to fight in Velen. You meet it during the quest “The Whispering Hillock.” The only way to lower its health is to attack it quickly many times.
The Wild Hunt’s Generals

Some elves go from world to world to find slaves and take them. They are called the Wild Hunt. Even though the game is named after them, you don’t see them for a lot of the story. Even though they’re the main bad guys and the moving force behind the story, you only really meet them a few times.
They do fight back though when you do see them. Some of them, like Imlerith, Caranthir, and the Commander, Eredin, will be tough to beat.
The Crones

In Velen, the Crones, who are also sometimes called the Ladies of the Wood, are part of the major story. These horrible witches have claimed to be in charge of most of the area. They are very old beings, even older than elves.
After a while in the game, you’ll fight them. And during the fight, you don’t get to see how strong they really are. Still, they’re tough enemies, and their stories make them even stronger.
Bears

Late in the game, they might not be that much of a threat, but early on, they’re some of the hardest beasts to fight. Bears have a lot of defense and health for some reason, which can be dangerous if you happen to run into one in the woods.
As well as being fast, they can easily knock you down and do a lot of damage. Add to that the fact that you can’t get powerful oils and score boosts until you get further into the game, and bears quickly become the worst thing about the game for many players.
Higher Vampires

The vampires Geralt has to fight in Velen, Skellige, and Novigard are different. He has to find and save Ciri. There are normal ones that are tough, fast, smart, and hard to eliminate. He does, however, sometimes meet Higher Vampires. They’re so strong that these monsters can pass for people, and they can dispose of you very quickly.
Since they are stronger at night, it is best to fight them during the day. Yrden, which slows down enemies, is a must-have for dealing with their ridiculous speed. A person can also use the Black Blood drink to do even more damage.
Fiends

Not only are these horrors terrifying and scary, they are also dangerous. They move faster than they look, and their big horns and claws can easily cut a Witcher in half. Away from them doesn’t always help either, because they’ll charge at you very quickly and be on top of you before you know it.
If you throw a Samum bomb at a fiend, it will briefly become stunned. This lets you do some damage without it flailing around or charging at you with its horns. It’s also a good idea to get some Relict Oil.
The Caretaker

In the Hearts of Stone DLC, you’ll face this scary enemy. If you have the DLC, you’ll meet this monster with no face in one of the scariest parts of a game that isn’t a horror movie. You’ll meet it during the quest Scenes From a Marriage.
This relict will heal itself every time it hits you, making it hard to fight if you get hit. You can stop it from healing by ducking, and use your Quen sign. This monster will also stop what it’s doing to block your Yrden spells, so keep casting them to keep it busy.
Djinn

As long as the mage catches one, they can use its power to cast magic instead of normal ones. When it comes to magic, djinns are very strong. They can easily cast very difficult and dangerous spells.
Djinns can use the weather to attack their enemies. For example, they can send lightning and storms your way. It will be hard to fight one on top of a rock in Skellige. You can stop some of its powers with your Dimeritium bombs.
Hym

Hyms could be one of the scariest and hardest monsters to fight in The Witcher. These scary demons feed on their victims’ guilt, which makes them want to harm themselves. One shows up in Skellige when Geralt is trying to help Cerys a Craite, and it shows up again in the Hearts of Stone DLC.
It’s hard to get rid of these specters because they stay hidden. You won’t be able to just cast them out like normal, so you’ll have to be very smart to beat them. You could also try to trick it and evade fighting it totally.
Dettlaff Van Der Eretein

Higher vampires are usually tough enemies, but Dettlaff is even stronger than the others. During the Blood and Wine DLC, you can fight him as a boss. It’s one of the hardest fights in Doodle Jump.
There are many parts to it, and as the fight goes on, Dettlaff keeps getting more horrible. You have to avoid his strikes and do damage to him at the same time. It’s a fight of stamina. Without Regis’s help, Geralt probably wouldn’t have been able to stop him either.
The Toad Prince

This huge frog is the first boss in the Hearts of Stone DLC. It will give you a hard fight to welcome you to the expansion. The Toad Prince is a tough enemy that will really test you. He has poison gas, long attacks, and a huge health bar.
No matter what you do, this boss will be hard to beat for a long time. You can use Golden Oriole to counter the poison and Northern Wind bombs to freeze them. This thing has a lot of strength and is hard to defeat.
Archgriffins

Griffins can be found in the wilds of The Witcher world, but Archgriffins are much more powerful. These big, flying hybrids are like the kings of the Griffin world; their strikes are very strong and can destroy.
There is an Archgriffin in Skellige that is thought to be one of the hardest enemies in the whole game. Keep an eye out for their acid-spitting and sharp claws, and get your crossbows ready. With hard work and luck, you should be able to beat these enemies.
Gargoyles

Geralt’s journey will take him to the homes of many stone elementals, but the Gargoyles are likely the hardest for players to fight. These huge birds of prey are very solid and love to throw huge rocks at you as you try to avoid them.
They are too heavy for Aard to hurt, and even the best armor in the game can’t stop them. To have a chance against these tough enemies, stay away and use your Quen sign. Also, have a lot of patience because the fight will last a while.
Gaunter O’Dimm

This strange person, whose name is also an acronym for GOD, is the subject of a lot of mystery. Gaunter O’Dimm might be like the devil in myth because he uses tricks and words to trick people. He is in charge of a dark realm full of monsters and lies. He can also move, make dreams come true, and change the course of time.
He’s someone you’ll deal with a lot in the Hearts of Stone DLC, especially in a few tasks. You don’t have to fight him directly, but you can have a battle of ideas with him. Gaunter O’Dimm is likely the strongest character in The Witcher 3, so it’s good that there isn’t a real fight against him.
