This book is quite honestly just a heavenly resource, containing answers to all the questions you could have about writing D&D content without having to sort through books upon books to try to figure out the standard way to format things. It also has helpful reminders about grammar and the proper way to put things in American English, which is also helpful.

I had a lot of fun with this adventure. It was my first introduction into solo adventuring, and while I didn't feel like replaying it, I'm not a replayer in general, and the character I made eventually turned into a fairly well-liked NPC in the game I DM for.

My only complaint about this book is that there aren't more puzzles in it! While I haven't used every one yet, I've used a few of them and read through every one multiple times. My players have managed to solve them all and have fun doing so, and it helps me save so much time coming up with puzzles myself that would likely be too easy or too hard.

This book provides a lot of amazing monsters - my favorites are easily the NPC statblocks as humanoid enemies are lacking in D&D. Behind that, I quite enjoyed the Demon Lord Aspects and made use of a few of them (including the Covergirl, Lolth) in my campagin to the delight of my players.

This is an awesome book that really provides an awesome amount of character options, even today!
