A really good set resource if you're planning any sort of subterranean campaign or adventure. You could build multiple play sessions and rich stories using any of the things described within.

One of the most original, inspiring and easily-playable RPG systems I have ever encountered. I have played quick one-shot games with Downcrawl, I have also played sweeping campaigns that have lasted for months with the same players. The game is easily customizable, endlessly inspiring and gives an amount of agency to both GM and players in a way that's rare these days! Downcrawl gives you room to explore, if you want to. It also gives you extremely solid foundations to build off of when you don't. 10/10

I'm absolutely blown away. 10 pages in I could tell this book was going to be something special. Now I'm in the closing pages and I'm stunned by the sheer creativity on display here. I'm itching to roll on these tables and see what kind of wild and evocative scenarios come out in a real game! Practically every page is dripping with good advice or entrancing flavor. This book feels like a must for anyone wanting to run an Underdark adventure.

A fantastic system for making travel in the underdark/deep down/underworld interesting and difficult at any level! The second arc of my current 5e campaign is focused on the "World Below," and my players said they still wanted travel/navigation to be interesting/difficult, but that can be really hard in a campaign going from 10th level on. So the lack of teleportation magic and the instrinsic difficulty of navigating shifting cave systems is a perfect match to make things interesting but not too complicated for them. Plus the no long rests while travelling rule! They were so nervous and excited when I told them about it!

Beyond the systems, the tables for making fun, weird, interesting folk and places to fill the world with are absolutely worth it by themselves. I've spent several days during breaks just spinning up extra interesting places and people for them to end up, and tieing it all to my pre-established factions. So much fun!

Magical. Genius. Inventive. I really enjoyed reading thorugh this book and look forward to integrating it into a campaign.

This is a great resource for anyone wanting to add some exploration to their games. Even without the travel mechanics, the tables for creating regions and denizens are incredibly useful!
