From publisher blurb:
Limoneags, and Kalidahs, and Orks, Oh My!
This massive monster supplement details over 300 weird and wondrous creatures drawn from all the Oz literature in the public domain by L. Frank Baum, Ruth Plumly Thompson, and Jack Snow.
This Faerie setting encompasses much more than Oz, from the skylands of Un to the underground world of the nomes, from the Land of Ev to Merryland, Ix, and the Valley of Mo.
These monsters are divided by ecosystem: the Isles, the Overworld, the Sky, and the Underworld. Also included are rules for closed domains and random encounters in each ecosystem. Challenge ratings range from 0 (Crawling Bird) to 23 (Choggenmugger).
So put on your silver shoes and step out onto the yellow brick road. Your Oz adventure awaits!
