This is a nice, short adventure of approximately 4 hours runtime which can be run as a one-shot or fill out a session of an ongoing campaign. Of note: The adventure can be incorporate seamlessly into the Storm King's Thunder campaign because the location of the inn (Dashing Satyr) lies along the way the characters will have to traverse for a quest in the campaign. The inn is described in detail, including the offered items, and the proprietor Wan Bai has a nice background story attached to her. Especially noteworthy are the maps which are offered. They are of the highest quality and will get the players into the right mood.
It has to be mentioned that the promoted level range of 1-3 has to be treated with caution. In most cases, a party of level1 or 2 will find their demise in this dungeon if the DM plays it by the book. This holds especially true if the players are beginners. The DM will have to adjust the difficulty of the final boss and one trap the characters encounter along the way if a party of level 1 or 2 should be able to prevail.
The adventure also offers room for further story developments. The whereabouts of the true villain remain unknown, and either the characters or the villain himself might decide to force an encounter at a later date.
In conclusion: You will have fun, so go right ahead and get it!
