How Do You Unlock Mutagen Slots in Witcher 3?

In Witcher 3, mutagen slots are used to increase the power of your character’s signs. There are a total of six mutagen slots, and each slot can be filled with a different mutagen.

To unlock a mutagen slot, you must first complete the “Blood and Wine” expansion. Once you have done this, you will be able to purchase mutagens from certain merchants.

There are four different types of mutagens: red, green, blue, and yellow. Each type of mutagen gives a different bonus to your signs.

For example, red mutagens increase the damage of your Igni sign, while green mutagens increase the duration of your Quen sign. Blue and yellow mutagens provide other bonuses, such as increased experience gain or increased critical hit chance.

To use a mutagen, simply drag it from your inventory and place it in the appropriate slot. You can only have one mutagen active in each slot at a time, so be sure to choose wisely! Mutagens can be swapped out at any time, so don’t be afraid to experiment with different combinations.

Mutagens are a great way to boost your signs and make them more powerful. Be sure to check out all the different types of mutagens available and find the ones that work best for you. With six slots available, you have plenty of room to experiment!.
