This is the third time buying the beginners box for me. Once in physical form, once in PDF form (for Foundry Importing). And now, as this premium module.
Far and away, this is the best way to teach somebody the game. The new maps are awesome, the overhead tiles add so much immersion to the game (watch your players go UNDER spider webs!), and the boxed text modified to make it even EASIER on the gm to ask for specific checks is awesome.
I got this for running as part of the Beginners Box Day, but already owning the PDF makes the cost such a good price that it's worth picking up if you haven't already.
All of that, is on top of the fact that the base beginners box is the best introduction to playing a Table Top RPG that I've seen. Each room introduces a new concept, one at a time, to help both the GM and the players ease into the game. And, it ends with a super iconic boss fight!
Pick this up, and you will not regret it
