Mutagens

Mutagens are used in combination with character abilities to give bonuses to your character Geralt of Rivia. These items are obtained from slaying monsters throughout the Northern Realms.

Types of Mutagen:

There are common, lesser mutagens, and then there are mutagens dropped from specific monsters killed for Geralt’s Witcher contracts.

There are also three colors of Mutagen: red, green, and blue. Each color coincides with the specific skill trees.

  • Red: Attack Power bonuses in the Combat Sign area
  • Green: Alchemy and bomb bonuses; increases Vitality
  • Blue: Increases Sign Intensity

Mutagen Slots

 

The ability slots in the Character Screen are divided into groups of three. Each of these has a mutagen slot to provide special bonuses to the abilities in that group. Since there are only three types of mutagen and four mutagen slots, double up where needed for the bonuses. If you use mutagens that coordinate with the abilities, you’ll get even higher bonuses; e.g. Green Mutagen combined with Alchemy abilities.

You start the game with no Mutagen Slots unlocked, but by the time you reach Level 28, all four slots will be unlocked.

 

Decoctions

Decoctions are for the experienced Witcher, thanks to their high toxicity and the risk that comes with them. Yet so worth it!

These are alchemy potions made with specific monster mutagens that Geralt gets during a Witcher contract kill. These provide great bonuses, but come with a very high toxicity, so it’s best to weigh your options before using.

  • Troll Decoction: Constant Vitality regeneration in and out of combat. For Witchers expecting multiple waves of enemies.
  • Ekimmara Decoction: A Witcher restores Vitality with every successful strike against an enemy.
  • Succubus Decoction: The longer the battle, the harder the Witcher strikes!
  • Alghoul Decoction: Adrenaline is generated more quickly by a Witcher in combat, but the effect is broken upon the first successful strike from an enemy.
  • Werewolf Decoction: Running, sprinting, and jumping outside of combat doesn’t use Stamina.

More will follow in my Potions Guide coming soon which will include how to make bombs and more.
