Quick Guide
Accessing your content
The Tarokka Deck is an addon .
These content packages are available via a dropdown menu in the Game
Addons section of the Game Details Page. Select the one you wish to add
and click on the blue Add to Game button beside the drop down menu. I would also add the info earlier in the description that this is already in the campaign: This Card Deck is also available within the full module version of Curse of Strahd . Hope that helps?
