My players and I very much enjoyed this adventure. I was looking for a way to ease into Tomb of Annihilation, and this adventure did the trick. We have since concluded our Tomb campaign after more than a year of adventuring, but we still talk about "Danny Darkelf," the NPC we created and promptly killed at the start of Cellar of Death.

Cellar of Death if a fine adventure, and it is a great alternate way to start Tomb of Annihilation. Highly recommend!
