This adventure seems like a great way to introduce players to a demonic monster as well as the Wizard Beads, which I find to be genius and I will be stealing for other games. Some good plot hooks and I like the Isometric map. Strong writing and easy to understand what's going on in it. Adequate amount of artwork for a short encounter but what is in it is very good and captures the OSR feel of the game. Overall a fun solid encounter to fill out a hex or a random encounter and worth the low price.
