    I went to the signal tower and looted the 4 chests, the one on the bottom floor, one on the 2nd and the two on the top and there was no diagram for the black unicorn :/

    Same for me too Spencer. It seems to be randomized but those chests have the best chance.

    And it wasn’t there for me as well, what a joke. Cleared the whole game and couldn’t manage to find the Oathbreaker armor or the Black Unicorn, the two items I wanted most, I’m not even surprised.

  8. Hi all, I found the diagram for this sword on Ard Skellig, in Kaer Gelen to be more precise.
    It’s at the top of the fort, in the room protected by a level 29 Katakan.

    The Tir Tochair Blade does 364-446 damage has 50% crit damage bonus 5% crit chance and 15% chance to cause bleeding and 2 runestones spots, it also requires level 46 and I think it’s better than the unicorn.

    looks shit compared to TW2 version

    I checked all the places above and nothing. I eventually found it at Clan Tordarroch Forge in the watery cave. Can’t tell you exactly where as the place is huge. But to get out I had to climb up a bunch of ladders. There are a lot of chests and other things to loot in this area. Not sure if the diagram is always there but I did find it.

  14. G

    There’s no possible way this info is accurate as I’ve had Black Unicorn since at least level 24.

    1. H

      i had that diagram in a chest during a witcher contract the missing brother in a huge cave

    2. N

      Me also, i have a lvl 10 Black Unicorn.

    I found it on my first play through. Just saw the name and didn’t realise it was a sword. Thought it was some random diagram for a stuffed unicorn… All I could think was boom chikka wow wow, Yennifer’s going to love this.

  16. K

    I got a lvl17 (also relic) version of this sword in Novigrad lol, was a nice surprise.

  17. C

    Black Unicorn can be found almost anywhere and numerous times
    The best version is the diagram you get from the Dark Legacy quest in the heart of stone DLC
