The Witcher 3: Blood and Wine unlocks the Mutations System when you complete "Turn and Face the Strange", a unique side quest in Toussaint with a reward you need to get ASAP. The Mutations System unlocks 4 new ability slots, while also allowing you to use a Mutation that has vast power, depending on your preference for weapon, defense, and sign. Below, we'll provide a full walkthrough of "Turn and Face the Strange" along with its many puzzles, then explain the Mutations System.
You can start the Turn and Face the Strange side quest after completing "Blood Run", the third main quest in the Blood and Wine expansion. Just make sure you're wandering around Beauclair in Toussaint, and a random messenger should approach and give you a letter (from Yennefer, or Triss if you romanced her).
Once you receive the letter, you're met with two options:
You should definitely tip the boy, as it's only 5 Crowns (and at this point you should have over 50,000 Crowns). This is also the easiest way to complete the Proof of Generosity task in a different side quest.
Yennefer (or Triss) will ask you to visit Orlemurs Cemetery near Lebioda's Gate (as marked on the map above), but when you enter the grounds, you'll find that the grave has been robbed.
You will need to use Witcher Senses and follow the footprints, but the trail goes cold. Open your inventory and use the Old Map of Toussaint quest item, which reveals your next location, where you can dive underwater and access a portal within the ruins.
Inside, you will want to follow the objectives through the tower, avoiding the floor spike traps (Quen mitigates the damage), and you will soon fight Guardians, which are spectral panthers weak to silver swords. Continue through the ruins below, where you will find a dead-end room.
Inside this room, there will be four stones on the walls that you can shoot with your crossbow. There's no time limit, so look at the stone squares in the images above and shoot them. They are all in the room with the locked door, so check the walls!
