    Tipp: This Contract is a good Target for the Even Odds Achievement
    The Witcher 3: Wild HuntEven OddsThe Even Odds achievement in The Witcher 3: Wild Hunt worth 66 pointsKill 2 monsters you have a contract on without using Signs, potions, mutagens, oils or bombs.


    You get this Contract Named An Elusive Thief (Level 13) in Novigrad from the Notice Board in Hierarch Square. Go to the Marketplace during Day and Talk to Sylvester Amello. Then use the Witcher Senses to the Thiefs House and follow his trail again.

    If you let him live you get a good Diagram for a Weapon: Gnomish Gwyhyr Steel Sword (if you have hit Level 42 :D)

    LavindatharConfirmed, I let him run off and got it. Didn't even realise there was an achievement for it

    CM TranceDo you have to do it before the "critical part" of the game? Because I can't find the contract on the boards and can't find this Sylvester...

    zeno2kI had to reload an old savegame and replay the mission killing him to get this unlocked

    WhyattThrashThere's an issue with lots of achievements in especially the GOTY edition that they don't unlock the first time you complete the objective. If you have an earlier save you can just try to redo it.

    xTMx VoytekI turned it in twice after letting him live and then once after killing him and got nothing. After doing a hard reset I reloaded and killed him again and it popped.. Definitely worth having saves before turning in achievement quests it seems.

    flipmodeXXIIIThe hard reset trick worked for me too.
