Creature Weekly Volume 4
A collection of seven illustrated creatures for use as challenges, adversaries, allies, or player characters in fantasy, modern, or science-fiction campaigns. Entries include the desert-dwelling humanoid idos, intelligent cactus-people called higgus, the sonic Cacophony Beetle, and the undead-hunting Sobekor. The volume also introduces the Archdaemon Guulloth and his guuldaemons, along with the Bosch fiend, a menu-based construction system that combines nine statistics blocks with fiendish abilities to create hundreds of variants. Each entry includes variant rules and genre-adjustment guidance for adapting the creatures to different settings.
