Stretch Goal #1 Unlocked: More Monsters!
11 months ago – Sat, May 03, 2025 at 10:18:33 AM

We blew past the first stretch goal! Thank you all for your support! If you want to see this project get even more full of goodies, don't forget to tell your friends about the project :)

Book Option Poll!

Want to participate in the building of this book? Respond to the poll by commenting on this update with the number 1–3 according to your preference!

Would you rather see:

  • 1) Scaling stat blocks for big bosses like the chromatic crabs (e.g. young, adult, ancient), so that you can run the bosses at multiple tiers of play.
  • 2) Bigger groups of thematically cohesive monsters and bosses from the same plane.
  • 3) A wider spread of invasive species types and CRs across the different planes (elemental planes, plane of shadow, feywild, etc.)

$20k Stretch Goal Unlocked: More Monsters!

Blowing past the first stretch goal gives me the perfect excuse to take a deep dive back into monster making! Here's a sneak peek of some monsters I've been cooking up stat blocks for in preparation for hitting this stretch goal:

These oozes evolved in a demiplane with accelerated time designed by a bunch of wizards in a guided experiment of the evolution of oozes. The CR 20 "royal ooze" absorbs other oozes into its body and hijacks their abilities to use for itself in a process inspired by real-world endosymbiosis.

$30k Stretch Goal: More scaling environmental effects!

I'm excited to crank out more environmental effects in this book. Here are a few I've been noodling on that might make the cut, although there are many more where this came from!

  • Gravity storms: clouds gather, a portal opens, and a whole city becomes suddenly heavier (or lighter!). It's easy to imagine how much of a disaster this would be (and how to scale it—modified falling damage, projectile speeds, etc.).
  • Reverse Detect Thoughts: imagine an invasive flower whose pollen causes you to uncontrollably project your thoughts in a wider and wider as the infestation grows. Perfect for starting wars, ruining parties, and creating a whole lot of drama.

Project I Love: Humblewood Beyond the Canopy

Hit Point Press has released so many incredible books, and I am a big fan of their design choices in the original Humblewood book. I absolutely love these books.

Return to the magical world of Humblewood where animal and birdfolk live, explore, and adventure. Humblewood: Beyond the Canopy takes you past the edges of the Wood to discover the continent of Wesden through a lush setting guide and globe-trotting adventure. 

Uncover frozen mysteries in the Crystal Expanse, ride the mighty gargaths across the plains of Firnveldt, find a warm welcome in Warrens away from the tempests that shake Stormcrag, and feel the pulse of nature in the verdant Tanglewilds. 

New playable races, classes and more await you in this long-awaited standalone Humblewood sequel!

The project ends in less than a week! Check it out here.

Thank you all for your support! This is a great start to an exciting campaign! 🎉🎉 

I can't wait to see how many stretch goals we unlock! Each one we unlock will make the project bigger and better—and give me the excuse to make some things I've been dying to design (like a compendium of botanical horrors). 

Stretch Goal #1 ($20k): More Monsters!

The first stretch goal is a batch of new monsters for the book! One of the monsters I'm excited about is an ooze inspired by real-world endosymbiosis—the process by which early single-celled organisms developed organelles like chloroplasts by enveloping other organisms. Just imagine what a humanoid-sized ooze could do by absorbing others in a demiplane dominated by oozes and slimes.

Let's hit that $20k :)

New Add-On: Play with the Creator

I made a new add-on available in the campaign! I'm opening up my table to welcome backers who add the "Play with the Creator" add-on to their pledge. I'll run the prequel one-shot adventure, The Whispering Wood for you and up to four other players (signing up separately)! I love getting to share this horrible little adventure with people, so I hope you decide to join me. You can update your pledge at any time to secure the add-on before they run out (I can only run so many tables while I write this book).

Projects by my Friends

I wanted to give a special shoutout to one of my friends, Josh at Lone Colossus Games. He's been a huge help to me personally as I prepared for this big project, but he also makes really cool books. His latest book, Intangible Treasures II is in the final 48 hours of the campaign! I've seen bits and pieces of this book, and I have to say: it's awesome. 

Check here to check it out!

Hunt the monsters, steal their power. The second, standalone volume in a growing series, Tome of Intangible Treasures II expands your options for 5e-compatible story-based rewards with:

  • Ritual and Harvesting systems that allow players to absorb the abilities of fallen enemies
