Friends and neighbors, this one’s different.
For years we’ve been talking here at Grailrunner about how imagination works — why certain images crack open your brain, why odd bits of history or art or game design suddenly ignite a whole setting, and why creators keep coming back to the well even when the world’s noisy. We’re always on the lookout for new ways to break into exciting and innovative designs, imagery, and above everything ruling it all…to tell new stories.
OK, so what’s the freebie?
Hold on – a little context first. It was a life-changing experience for me personally to write and design our most recent publication, SALT MYSTIC: BOOK OF LOTS, a western-themed science fantasy roleplaying game book built around the fortune-telling mechanic of bibliomancy. I’ll tell you why. To build out the world of our signature IP at Grailrunner, I needed a ridiculously huge amount of outlandish concepts, crazy ideas, and just cool, new stuff! I kind of went down the deep well of concept art techniques like mind-mapping, thumbnail sketches and iteration, shape carving, scribble ideation, and mood boards. That stuff is like adrenalin for an imagination, honestly!
It was so impactful, in fact, that I wanted to go deeper. Yet it struck me that art school and super expensive concept art classes with some of the working masters in this field aren’t going to make sense for me. I imagine they don’t make sense either economically or logistically for a lot of folks like me. So it got me thinking I’d like a simpler, streamlined, but focused way of drilling deeper into JUST the parts of concept art that would help me – the techniques that help break your imagination’s walls to explore new ideas.
Sounds great. What did you do?
We don’t charge for AI-generated stuff at Grailrunner, and we always point out its use. In fact, we’ve built out some pretty amazing stuff that we give away just to experiment with possibilities and hopefully inspire anybody that hangs out here with us. If you keep coming back here, maybe you’ll buy a book or a game or drop a LIKE on our Facebook page. That’s the idea.
My absolute favorite giveaway so far has been an entire board game mockup set in the seas of Tolkien’s Middle Earth. Awesome. I just got a Silhouette Cameo 5 for my birthday, so I’m planning to break that puppy in with the printable tokens and cards there.

And specifically now for concept art techniques?
I curated a portfolio of concept art masters, provided an outline of content for my ideal coursework for a class, and instructed ChatGPT to act as the composite concept artist (meaning all those people) and write the chapters one by one for my outline as well as a preface and afterword. Then I went chapter by chapter and had it generate impactful exercises unique to each section which a student could conduct on their own with an internet connection and pencil and paper.
I mocked up illustrations of concept art techniques and examples to ensure the book is illustrated well and clear in what it’s saying. Then I bundled all of that into a professional textbook template and converted it into a pdf.

Inside you’ll find:
- A step-by-step ideation → thumbnail → refinement pipeline
- Practical exercises after every major section
- Guidance on using digital tools without letting them boss your imagination around
- A tone that assumes you’re already creative — we’re just lighting the boosters
That sounds nice. Your header says it’s “interactive” though. What’s that about?
I told you here that I’ve used AI tools to resurrect old masters and have them critique my own art to provide detailed feedback on what I could improve. That works surprisingly well, so I added instructions in the Preface on how to upload this very pdf to a student’s own instance of ChatGPT then have the AI act as the composite author critique their own uploaded exercises.
I mean. That’s totally possible and crazy to think we can do that kind of thing for free now. Anyone upset about AI being used like this needs to…and I say this with love…recognize this kind of workflow is an unstoppable industrial revolution. Your competitors are doing it.
Give me a download link, man! You’re killing me.
Grab the masterclass, run through the first exercise tonight, and then show us what you made. We’re still building this creative network in public — the more people who are sketching, painting, kitbashing, and worldbuilding alongside us, the weirder and better things get.
Enjoy, and make sure to let us know what you think.
Till next time,
