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
  • 100 fully fleshed out monsters complete with stat blocks, art, lore, adventure hooks, and tactics
  • 300 new boons and charms that can be bestowed using materials harvested from slain creatures
