From publisher blurb:
What if Every Horror Movie Was Written by Lovecraft?
Dive into the unknowable, the unthinkable, and the unspeakable with this collection of over 70 monsters for popular fantasy role-playing games.
This collection includes monsters inspired by popular horror movies and a diverse array of creatures from horror writer H.P. Lovecraft’s original works. These monsters are true to the source material, which contains surprises for jaded adventurers. Players who think they know everything about Lovecraft’s mythos might be surprised to discover that shoggoths glow, wamps chuckle, and vooniths howl. There are plenty of aberrations in this collection, but there’s also fiends, undead, and a few plants.
This PDF has a bookmarked table of contents, with monsters linked by creature type, challenge rating, and environment. Challenge ratings range from 1/8 to 25.
