Here are all the mutations that can be applied to Geralt and how to get them.

After spending two Ability Points and two Greater Green Mutagens your blood will become toxic.

Even at basic levels, its another source of DPS that makes fights a lot shorter.

Witcher 3 Mutation

11Deadly Counter

Deadly Counter is similarly cheap requiring only two Ability Points and two Greater Red Mutagens.

This one is a bit more niche, but under the right circumstances is brutal.

10Magic Sensibilities

The other cheap mutation on this list is Magic Sensibilities.

Witcher 3 Toxic Blood

It costs two Ability Points and two Greater Blue Mutagens.

This mutation is better for players that like to use signs.

With this mutation in place, signs can now deal critical hits.

Witcher 3 Deadly Counter

The chance of a critical hit occurring and the damage it deals increases with Sign Intensity.

It also has the effect of causing enemies to explode if killed by one of these critical hits.

Its considerably more useful than Toxic Blood as it applies a damage bonus to swords and Signs.

Witcher 3 Magic Sensibilities

This mutation is different from the others in that it focuses on durability rather than damage output.

This is great for Adrenaline based builds or anyone who needs more durability rather than damage.

It has a tricky damage boost that takes some skills to utilize long term.

Witcher 3 Euphoria

Where things get tricky is that every time you receive damage the counter resets back to 5%.

It also causes either a dismemberment or finisher to trigger whenever you deal a fatal blow with a sword.

It will dramatically improve the effectiveness of your crossbows.

Witcher 3 Mutated Skin

If an opponent has full health when hit by a Crossbow theyll lose 15% of their health.

Its very handy if you find yourself usingAard Signsa lot.

Whenever an Aard Sign is cast there is an additional 25% chance of the opponent freezing.

Witcher 3 Bloodbath

If the opponent is frozen and knocked down it will die immediately.

Even if the opponent doesnt freeze each sign will get a major boost to damage.

Its very effective when fighting groups.

Witcher 3 Cat Eyes

It gives a nice boost to swords that have sign damage.

Whenever you draw a magic, unique or Witcher sword its sign damage will increase by 50%.

Witcher 3 Piercing Cold

Witcher 3 Adrenaline Rush
