Last month I backed up Joseph Bloch's latest Kickstarter for the 10th Anniversary of his mega-dungeon "Castle of the Mad Archmage". I chose the digital copy since I already have the original one in print, and it will make a suitable addition to it. Everything that the Greyhawk Grognard has ever published about it, all in one single tome!
This month Robert J. Kuntz, through Three Line Studio, digitally released "The Return of Robilar". A complete guide of this iconic D&D and World of Greyhawk figure; his stats, history, magical items, companions (Otto and Quij), mounts (3 green dragons!) and more. A must have to celebrate the Lord of the Green Dragons 50th birthday!
