The Witcher 3: Wild Hunt is an RPG where the possibilities are seemingly endless. The world is vast, the species of monsters are limitless, and you can enhance your character, Geralt, in a number of strategic ways. From weapons, armor, and decoctions, to bombs, signs, and mutations, a player can craft Geralt into the most powerful being alive. Today, we’ll discuss the different mutations a player can craft in the game and rank them from the worst (as in, the least useful in combat) to the best.

12. Toxic Blood

Though Toxic Blood is not as great as the other mutations listed ahead, it’s still a great starter mutation that will come to your aid during battle. Each time a player is struck during combat, their foe will suffer 1.5% the amount of damage for every level of toxicity Geralt has. Geralt’s toxicity reaches a maximum of 150%, so a player has the ability to deal a significant amount of damage to their foe.

• Alchemy Mutation

• Requires 2 Ability Points and 2 Greater Green Mutagens

Toxic Blood Usefulness Score: 25/100

11. Deadly Counter

Next we have Deadly Counter, a powerhouse of a mutation that allows the player’s swords to inflict 25% more damage to humans resistant to counterattacks and monsters. Not only that, if your enemy’s vitality is below 25%, Geralt's counterattack will immediately activate a finisher, leaving your foe dead with you coming out victorious.

If you love using signs during combat, then the Magic Sensibilities mutation is for you. This mutation allows signs to deal critical hits to opponents, a huge perk when dealing with the more difficult foes. Opponents also have a greater chance of exploding - yes, literally exploding - when struck with one of these critical sign hits. Exploding gets the job done quicker, I suppose.

• Requires 2 Ability Points and 2 Greater Blue Mutagens

Magic Sensibilities Usefulness Score: 35/100

This must be how it feels to chew 5 Gum. Perfect for fighting a large group of enemies, Adrenaline Rush increases attack power and sign intensity by 30% per enemy. So when battling a group of 10 enemies, the bonus is 300%, a massive increase in power for quick and efficient kills.
