The entire map set in this series is absolutely amazing. The attention to detail on the maps is better than anything else I've ever seen. And this "boxed set" by far is the best one of the lot. Like all the maps that came before it, this dungeon level only left me wanting more.
The room template pages included with this set are an awesome idea, and I actually wish that 0one would publish similar room templates for each of the other 9 levels.
The customizable options in the pdfs, being able to turn off or on individual layers for printing is a great idea, and I'm glad they did this for all maps in the series. A minor caveat emptor about this feature however, is that these pdfs will require adobe acrobat to use. If you are using another reader, it is unlikely that you will be able to take advantage of this.
The only even mildly disappointing thing about these maps is that they appear to come with a grid marking out 5' squares, where in my opinion, 10' squares would have made the maps seem considerably more monolithic.
Other than that, however, it's spot on perfect. The only thing left to add to this series, IMO, would be room templates for each of the other 9 levels. Of course, even more levels wouldn't hurt either.Rating: [5 of 5 Stars!]
