I've recently used adaptable NPCs in a campaign and found it inspirational and useful. The NPCs within gave me great ideas. I was easily able to scale them to an appropriate level by removing some skills or increasing hp. The creative combinations of features and attacks gave my players some great surprises, but still felt like they had a theme for each NPC.

I appreciated the gender diversity in the book although more diversity in characters would be nice in the future. I'm also tired of female NPCs being depicted in the same way from product to product. There were some small typos/editing errors, but they did not distract from the quality of the NPCs.

I bought this as soon as it came out because I was very excited about the product from description alone. I have thoroughly enjoyed reading through these familiars and cannot wait to include them in a game. Heck, I'm excited just to have it as a coffee table book. The ideas for these familiars are extremely clever with every detail clearly closely considered from personality traits, to price, to stats, to summoning materials. In addition, the art and layout of this book is thematic and consistent giving the feel of a true buyers guide. On top of that, Bearthazar has a personality of his own with the flavor text. I would love to see the addition of an NPC guide on including Bearthazar himself in a campaign.

My only critique is that I quickly noticed some editing/typo style issues, but none of them were distracting or confusing. So, overall, not a bit deal.

Anyone and everyone should buy this book and I will be purchasing more from these creators ASAP.
