DriveThruRPG is running a Halloween sale, in which a bunch of stuff is 31% off for the next seven days or so (as of this post). We opted into this sale, but DriveThru didn't put everything we wanted on sale, so we went ahead and discounted the rest of the stuff that we wanted to include.
There's also a monster design contest going on over on the Dungeon World reddit. First place gets you a free illustration of your monster by yours truly (colored by Melissa, of course), a free monster class from us (you choose, but it can't be Playbooks of the Dead because that's four monsters) and Victor's Halloween Party Bundle.
Second place gets you the Halloween Party Bundle, which is still great because Victor is one of the few guys making Dungeon World classes that does more than the cover-plus-two-page thing. He also creates pretty strange things, like a possessed/haunted kid and a scarecrow (though there are some "normal" things like a barbarian and scoundrel).
A Sundered World: Player Fragments, the first supplement for A Sundered World, is finally out!
If you're looking for a class that lets you play almost any were-thing you want (plus a bunch of related extra content), then check out The Therianthrope. There's also The Dragon, a class that lets you play almost any dragon-ish thing you could think of.
By fan demand, we've mashed all of our 10+ Treasure volumes into one big magic item book, making it cheaper and more convenient to buy in print (which you can now do).
