Project Update: Fiendish Forge: January 2026 Update

Howdy folks!

Hope everyone's year was well-rested.

Today's update is pretty straightforward: we're still internally reviewing the completed book.

Currently, we have 165 pages reviewed. Along with reviews, cleanup, and rebalancing, we're also getting more art done for the book to fill any open spots. Right now, the book is around 340+ pages and will probably grow a bit more as the table of contents and appendices finish up.

There is no release date at this time, but when there is, we will be sure to let you know. As always, the work is done when it's done, so when you have the book in your hands, it will be as complete as we could have made it.

Not much longer now. Thank you for your continued support!
Brett

Project Update: Core Book Content COMPLETE!

Hello everyone!

I'm thrilled to share a huge milestone with you - all monster content for Fiendish Forge is officially complete!
This includes materials, magic items, monsters, quests, and all other core book components. With this, we are now entering the final review phase before releasing the book.

What’s Left to Finish

We’re down to the final steps:
Monster Review
Our team will conduct a thorough review to correct errors, give final polish, and ensure consistency throughout the entire book.
Rulesets
These are largely complete. We are reviewing for clarity and may add one or two miscellaneous rules if needed.
Monster-Making Rules
These rules are entirely written (they were used internally to create the book’s monsters) and need to be moved into their final section of the book.

What about Playtests?

Last month, we mentioned the possibility of running one more playtest before finalizing this section of the book. After reviewing our progress, I decided to bypass last month's playtest. Since we were so close to completing the entire core book, focusing effort on another playtest felt unnecessary and would slow down our progress.
We’ve already received a lot of valuable feedback from previous playtests, as well as internal testing, and I've been pretty satisfied with the results. 

Release Window?

I am not ready to announce a release date at this time, as Io Publishing has always worked on "the book is done when it's done" - and I'd hate to let folks down with any unforeseen delays. What I can tell you is that we will be releasing the digital PDF and digital maps to our backers and pre-order customers first, before making them available to the general public. Think of this as early access for supporting our Fiendish Forge. This will allow us to get even more feedback and make any final updates before sending the book off to the printers, where it will be immortalized forever. Once the physical book is finished and in our warehouses, we will then release everything publicly. 

Thank You for Your Support

Your support and patience have brought us to the last stretch of development on Io Publishing's second major book. I look forward to sharing more as we progress into the final stages.
Thank you again for helping bring Fiendish Forge to life.

Project Update: Fiendish Forge: October 2025 Update

Hi everyone!  Brett here with your monthly update on Fiendish Forge!

Progress Report:

Here is where we are at:

Writing: | 90%
Design: | 85%
Art: | 98%
Total: | 91%

Progress continues, testing is good!

Running the new Elites and Bosses feels great in my games, and we've been playtesting over at the Io Publishing Discord. I feel confident and comfortable with the system we have in place, and excited as Monster designs and development continue!  Right now, I've finished with 31 out of the 49 stat blocks for the book. Elites and Bosses especially take a lot of time since they are very involved stat blocks, but we're moving at a good pace! Once the stat blocks are finished, I'll be able to move on to monster creation rules (Underlings, Elites, and Bosses) - which I'm hoping won't take as long.

November's Playtest: Madam Hush


After completing all the data for last month's playtest, we'll move on to our next release candidate, Madam Hush! I'm looking forward to your thoughts on this classic World of Io encounter.  As always, be sure to join our Discord if you're interested in being part of the playtest: https://discord.gg/e9RCf8bFke 

That's all for this month! Take care, and look forward to next month's updates!

Project Update: Fiendish Forge: September 2025 Update

Hi everyone!  Brett here with your monthly update on Fiendish Forge!

Progress Report:

Here is where we are at:

Writing: | 90%
Design: | 80%
Art: | 98%
Total: | 89%

Progress is moving along!

Been doing some personal tests, as well as in my streamed games, and have been satisfied with the results! I'm about half way through redesigning all the monsters. I'm hoping to be close to done (or maybe even finished) by the end of the month. Just finished a big move this September, and about to go on another trip, but once that's done, I should have more time to dedicate to Fiendish Forge.

October's Playtest: Fallen Hero

A foe who has mastered all class styles.
Once I'm, back from my trip, our next playtest will be the Fallen Hero! This Boss CR 10 has abilities from every class in standard 5e systems and should be an encounter with a lot of familiar variety! Look forward to it! Be sure to join our discord to participate in the playtest: https://discord.gg/e9RCf8bFke 

That's all for this month! Take care, and look forward to next month's updates!

Brett
