As a newer DM, this is really helpful in making adventures that are more than hack and slash. It is hard to find this kind of stuff and there are suggestions for how to incorporate the puzzles into adventures, which I find helpful.

I can see myself using this product every session I run. It is nice to have ready made NPC's that cover a range of levels and they seem well balanced. Between this list and the Monster Manual, there aren't a lot of gaps left that need to be filled when I need an NPC for my group.

I am also impressed with the professional quality of the product. The layout looks like the listings in the Monster Manual, which makes it easy to use.

I would highly recommend this product for both new and experience DM's. It is a nice list to have handy for when your players do the unexpected!
