I am always surprised when I learn that somebody missed something of ours, but it's not actually a surprise to any conscious being - I don't promote the stuff we do as much as I could. Generally it's because I don't want to annoy you. But too many people worked too hard on it for too long for me to allow my usual horseshit.
At root: in concert with Wizards of the Coast, the home of Dungeons and Dragons, we have created an honest-to-God, official supplement designed to invite players and Dungeon Masters into the world of Acquisitions Incorporated. This sort of arrangement is unprecedented to my knowledge, and I'm still freaking out. The book, whose handsome cover was created by Mike Krahulik, looks like this:
Preorders from our store include a special, free gift, though it's possible you may want to purchase a second one, which you can do from the Purchase Options dropdown. I present to you: The Green Flame Pin, which we've had in our back pocket for just such an occasion. It's pretty fucking cool and uses a new process, the specifics of which I think you'll be able to determine very quickly.
If you would like to crown this extravaganza with a conceptual cherry, consider the Dungeon Master's Screen made by the incomparable Kris Straub and myself. It is essentially a parody of the official 5E screen and has very little information in it that could possibly be of any use, although it's possible that something useful snuck in there during an ill-starred edit. There are more shots on the store page if you have had a bad day and desperately need evidence of a world where whimsy still exists.
This raft of crisp preorder goods ships from the warehouse on June 18th, so you may want to sequester these fascinating artifacts into their own order. There, I did it: promoted my own merchandise. Now it's not just my mom doing it in the Wendy's Drive-Thru.
