Special Red Mutagens are incredibly useful for players intheWitcher 3.

Thats a very nice bonus to damage output making them valuable to melee centric characters.

There are a number of different monsters to hunt down to obtain these Mutagens.

Witcher 3 Werewolf Wyvern

Alghouls can sometimes be found in large battlefields where multiple bodies are found.

Guranteed Alghouls will appear in the Contracts Woodland Beast and The Mystery of the Byways Murders.

Necrophage Oilwill help when hunting these creatures and theyre particularly susceptible to Axii signs.

Witcher 3 Alghoul

Even then they can be tricky to fight and are hard to take down in a crowd of Ghouls.

Theres another one that can be encountered during the Contract: The Griffin from the Highlands.

There is also Opinicus thats part of theContract: The Creature from Oxenfurt Forest but its quite the monster.

Witcher 3 Archgriffin

In general this is a hard Special Mutagen to obtain.

7Doppler Mutagen

Dopplers are capable of dropping the Doppler Special Red Mutagen.

The Doppler in the quest Skelliges Most Wanted will not drop one.

Witcher 3 Doppler

That means the player can only obtain one in the entire game from the Doppler in An Elusive Thief.

Relict Oil is highly recommended when getting in a fight with a Doppler.

Hunting them during the day is highly recommended as they have stronger regeneration at night.

Witcher 3 Katakan

The Yrden sign is very effective against them.

Interestingly they can also drop Lesser Blue Mutagens.

The only downside is that the drop rate is a bit lower when compared to other monsters.

Witcher 3 Nekker Warrior

They can be found throughout No Mans Land.

A single Nekker Warrior isnt much of a threat and even a group isnt too much of an issue.

Players can carefully farm groups using Ogroid Oil.

Witcher 3 Succubus

Theyre also great to farm for Monsters Essence, Lesser Blue Mutagens, and Lesser Green Mutagens.

One is Salma who is encountered during the quest Deadly Delights.

The other is found in Ard Skelling during the quest Practicum in Advanced Alchemy.

Witcher 3 Water Hag

Having Hybrid Oil can make the fights much easier.

3Water Hag Mutagen

Water Hagsare another fine source for Special Red Mutagens.

They can appear in Velen, White Orchard, and Skellige in different variations.

Witcher 3 Werewolf

Water Hags can be a bit tricky to fight thanks to their mud slinging and swimming abilities.

Necrophage Oil helps a lot.

Using Northern Wind to freeze her in place along with Quen and Igni can also do wonders.

Witcher 3 Wyvern

2Werewolf Mutagen

Werewolvesare a source of Special Red Mutagens.

Werewolves are very fast and capable of leaping large distances.

Fighting them can be very challenging and having a silver weapon is all but mandatory.

The Witcher 3

There are a number of these monsters encountered in the game.

One Wyvern can be found during the Contract Patrol Gone Missing.

They can also be encountered randomly in the wild, but those have lower drop rates.

By far the easiest way to get aWyvernMutagen is the one found in The Most Truest of Basilisks.

This creature is already injured and the player has backup to take it down.

Wyverns can be tricky to fight given their powerful poisons and swooping aerial attacks.

Golden Oriole helps negate the worst of the poison and Grapeshot can drop these beasts from the sky.

Hunting Wyverns is a lucrative activity given the abundance of materials and ingredients that drop from them.
