This adventure is pretty solid. It's part of a larger 4 or so part series of related adventures but I plucked it out on its own and inserted it into my ongoing campaign with out much trouble. The upside to using it in sequence is that it comes with several maps including the local town and the local region if you want them, including a high level magic user who acts as support/patron/quest giver, but that's easy enough to remove if it doesn't fit your setting. While those are great I would rather have not had those and had maps of the the tower itself where the final series of encounters takes place which unfortunately are not included. Thankfully finding generic tower maps is not a difficult task. I also would like to have seen a bit more information on Zalath, their goals and connection to the world but if you're using it as a one shot its not absolutely necessary and if you're splicing it into your ongoing campaign you can use whatever feels most applicable to your setting. All and all while it could have been better it was a very enjoyable adventure and for once wasn't crazy loot heavy for a prepackaged module making it easier to add into your campaign.
