To play multiplayer or to just get the "GOG-exclusive Treasure Key content" the game asks that I first setup an online account (separate from the GOG Galaxy one). But, to do that I have to create a user name, password, and enter my "serial number". Where is my serial number?

Thanks.

go to your libarary click on more & you will find serial number their.

dont forget to put caps lock for 1 letter of password

hey man went to libary to look for ser num there is no option for more.

Do not use Galaxy for your key. It's not there. Use web Gog, My account-Library-Click on Victor Vran- on view download page (default page) you will see your Treasure Key. Click on More and you will see your serial key. To redeem your gog treasure you have to use your serial key to create/login first, then in single player game, press esc-option-redeem key.

Thanks! That worked.

Yeah I noticed that, still if I wan´t to access the full functionality of the game (multiplayer) then I need said account. LANing ARPGs is fun and I much prefer setting up my own LAN to the limitations of online gameplay.

Yeah I wish it was lan as well =\

Thanks for helping me too! I couldn't find the serial as well.

I put my serial key in and it says server returned bad user code plz explain thx

So I don't need a serial key to play the game offline at least?

I also have the same message ...

There is a problem with the keys that Gog has we give?

Be warned, if you play offline you will not get the treasure scrolls which give you unlimited number of side quests with rewards.

Hey, sorry for the necrobump but I THINK I may have figured out the potential problem.

I believe you have to include the dashes that separate every set of four character when creating the online account.
