Because the number of backers was significantly higher than I originally expected, I have switched from DriveThruRPG "print on demand" fulfilment for the hardcovers, to an offset printed hardcover.
An offset print run will give me a much better quality book, with features like sewn bindings (instead of a glued, 'perfect bound' spine). This will be stronger, and lie flatter at the table. It does also mean the fulfilment time will be slightly later.
I have created new tier, "Chimeramancer," for newcomers who are choosing a hardcover.
DriveThruRPG doesn't allow me to update any details of rewards, once people have chosen them. This means that the "Errant Sorcerer" tier is incorrect—if you chose Errant Sorcerer you will get an offset printed hardcover, not a DriveThruRPG print edition.
