Oooo, you guys. This short but useful supplement is a great adaptation and discussion of the works of H.P. Lovecraft, transforming some of his lesser known creations into interesting encounters, spells, and feats. Great conversions, really interesting choices, and a breakdown by the authors of why they chose these elements and how they came to the results. I had never thought about how the Terrible Old Man had dispatched his would be robbers, but really interesting twist that could be the seed for a one off or something to use in your game if the players anger the wrong person. And who doesn't love a Cat Swarm? Worth the price alone.
