    This achievement is gained by unlocking a mutation after completing the quest "Turn and Face the strange". This can be done on any difficulty.

    To start the quest complete the main quest "The Beast of Toussaint" and you will be in a warehouse next to then river after fighting a vampire. Go up the street to the south and there should be a quest marker (about where my marker is on the map below). You do not have to complete the main quest, but it follows on nicely and smoothly if you do.

    Go towards it and a cutscene should start. You will receive a message and start the quest. Follow the quest until the end in the laboratory (for help reaching it see puzzles below) where you will get the ability to press "y" in your character menu to develop mutations. You will need greater mutagens and skill points (2 skill points and 2 greater mutagens of either red, green, or blue), I found these in containers throughout the elven ruins and lab, so loot everything you can.

    There are two puzzles in the elven ruins:

    Puzzle one:

    Open the door in the broken room with the rope. There are four plates on the walls that you can shoot with your crossbow. One to the right and one to the left of the door, one on the broken wall above the rope and chasm, and one opposite the last on the normal wall.

    Puzzle two:

    Navigate through the portals. The statues in the centre of the rooms face the portals you must go through. From the entrance to the room, go though the left portal. In the next room the portal is straight ahead, drop down towards the statue then climb up to the portal. Finally in the last room stay on the floor you start on and follow it around, jumping over a broken section to reach the portal.


    Note: a potential bug is that the achievement simply doesn't pop even though you have a mutation. Try using a potion of clearance, then doing a different mutation. Thanks to Bastiaen for this bug and fix.

    BastiaenI've unlocked a mutation, the one for freezing Aard, but no achievement. Anyone else having this problem?

    QozulPresumably that means you also unlocked "Magic Sensibilities" mutation, which is the one I unlocked. Have you checked that the achievement isn't on "Done... Unlocking"?

    BastiaenYeah, the achievement is unchanged, and that is the mutation that I got. But still no achievement. I'll have to try a clearance potion.

    Dr NeoI have the same problem. I've unlocked 3 mutations and no achievement at all. I will try reloading an old save...

    QozulThis was a recent comment on my guide for "Playing House" from someone for whom that achievement was bugged, a similar fix may work for you:

    "Finally got it to unlock by doing a hard reset of my xbox and then loading a checkpoint that the game made from when partway through buying all the upgrades and buying them all again"

    Loadme TacosI did the quest, and when I did the first mutation, the achievement pop out. No problem here. Thanks.

    WhiteWolF IIIII did this, got the Sword at the lake and have all the Skellige Gwent Cards. All in all 3 achievements, which did not pop. Seems to be a problem there. Have a save just before I got the mutation, just in case.

    BastiaenUsing a potion of clearance to remove my sign mutation, then unlocking the combat mutation, got me the achievement.

    No you don't, I've got the quest and running through it now. So for those doing secondaries & exploring before taking on the main quest line you don't have to progress to get this one just so you know :)

    *After having finished the quest, go to mutations screen and press Y to further develop mutations; Deadly Counter, Magic Sensibilities or Toxic Blood. Upon "researching" the mutation and successfully doing so you will unlock the achievement.

    phenom57I had the same problem with it not unlocking. Clearance potion didn't work but the hard reset did.
