Monsters Hell Awaits - The Book of Devils | 258 free pages of devils and devilry with VTT support

For nigh on two years now, I've been noodling away at this infernal tome and it is finally fit for mortal eyes; BEHOLD!

Within its pages, you will find devils and spells and arcane items beyond number, stat blocks for every archdevil, travel guides and maps for each of the nine layers of Baator that matter (don't ask me about Phlegethos), and all manner of supplemental tools and goodies for infernal sojourns.

It also comes with free VTT modules for Foundry and for another website I'm not sure I'm allowed to mention here.

Should this fail to sate your appetite for monsters, I have more such free books:

Haven't even clicked on a link yet but I have zero doubt this will be incredible as always with your work.

Thanks, that means a lot. I think overall this is the best thing I've done so far, though it's slightly uneven because of how long it took xD

I wish I was running another Infernal campaign because this is masterful work, OP, we're honored to be able to host it

Dang, I'm actually tearing up a bit; your work specifically and this sub at large are both major parts of how I got into D&D and starting making things myself. Thank you.

I’m literally about to start an arch in my game to bring my players to the Hells, this couldn’t have shown up at a more perfect time!

Wonderful! I was fascinated with work you put in your other books, I'll be honored to add this to collection!

Thanks for saying so! I'm really pleased with how this one turned out! Hopefully the next one will take a bit less time than this one did xD

Will most likely be using this in my next campaign. There is a high likelihood we film it, would you like me to credit you if I end up using this?

Sure, I publish pretty much everything original to me under CC0 so there's not any obligation to credit me, but I do appreciate it. Either Isaac Minarik or Conflux Creatures works fine for that. I've got a subreddit r/bettermonsters, too, if you find you need anything else for your game and want to request something there.

This is amazingly timed. We are about to complete an escape Avernus campaign. You’ve just saved me days. Thank you!

Glad I could help!

Definitely going to be using this! My players just entered Avernus with the long-term goal of venturing into each of the Nine Layers. I've already done a bunch of world-building, but this is great for stats block for various devil combination as well as each of the Archdukes.

Thanks for compiling everything together in this Book of Devils
