The map on the cover is not only a great illustration but also very legible for use in a game.
I liked the commitment to one theme throughout the booklet. Many of the Magic Items and Treasures are really interesting, I especially liked the Blackhand Staff and the Vanishing Pipe.
I would have preferred if the Lava Tubes and the Ravenous Temple used two different letters, such as "L" and "R" instead of sharing "A". If I ran this scenario, rather than progressing in the presented day order, I would roll a d12 on the Timekeeping table, saving the final 2 events for last.
