Solidly written Old School Adventure. Too much of the module is save or die for my taste. Some examples : save or drown, save or be crushed, save or be cursed to lose 1d10 health every ten minutes. (A death sentence at this level)

Seems good for a "Roll up new characters and see who dies last" gaming night, but not useful for an ongoing campaign.

Another pet peeve is that magic effects are not better called out for the GM. If a player uses detect magic to looks for traps/items it takes a significant amount of reading to decide if a trap or mechanism is magic. Also challenges seem to assume intelligent players would be just circumvent them. Put in a puzzle requiring backtracking? Even odds my players just bypass the portal with a maul rather than go back for items to solve the puzzle. (They will solve it, but then delight in destroying the puzzle rather than stooping to its demands and thus avoid other possible traps and effects)

This module is so darn seductive. It reads so very easily that the information jumps out at you. I feel I could run it for a group with no preparation at all. Who ever did the editing and layout did a fantastic job.

It also does a great job of covering the feel and mechanics of the Jadepunk setting. I was on the fence about the setting. I like the mechanics but I didn't really want to use the setting itself since I am heavily invested in another setting currently. Well this module made me change my mind. I am going to let my group explore Kausao city as they wrote it. 1) So i do not have to tinker with these modules as they were lovingly crafted and 2) I fear I might tweak something only to later learn it was a deliberate wrong note intended as a hook for an event in a later book.

Get this module. For the price you will not regret it. Heck get it for the presentation alone.
