The Harrow Deck is now available on Pathfinder NEXUS! Not only does this give you an easy-to-read version of the Harrow guidebook, but it also includes an interactive Harrow reading tool. Once you unlock the Harrow Deck source, click on the “Perform Readings with the Harrow Deck Companion” option from the table of contents or the opening of the book, and try your hand at fate.
If you encounter any issues with the Harrow Deck booklet or card companion, let us know in this thread.
