In addition there are new monsters Mr.Nordin contributes the Yix'Caahl, Enslaver, and Omniscient Oracle of the Refulgent Maze monsters; and Doc adds the Predatory Mantis, Swamp Fell, and Nameless Folk. These monsters are very Lovecraftian to say the least. They fill in the giant monster category along with most of the 'what the hell' is happening sense we've come to expect from this setting.
A note on "magic items" the magic items of the setting are built like artifacts. The alien technology is one of those things that players will be grabbing for as soon as they start dungeon crawling. However unlike most 'magic items' there are cultural taboos & such to items like the infernal pigments of the Bone Men can get one killed. While the Rejuvenating Bath and Plains of Whispering Grass are magic items that seem right out of a Lovecraft story.
Final thoughts, this book packs lots of stuff into a very small package. THE MATERIAL IS MATURE. DID I MAKE THAT CLEAR ?!? If you don't like it then please don't download it. There is really no reason why this couldn't be used with other Retro clone, Swords + Wizardry, Labyrinth Lord, Mutant Future, or regular original edition Dungeons & Dragons. I personally think its worth the download & have been using it since 2009.
Its free & can be downloaded Here
