In The Monsters Know What They're Doing, the essential tactics guide for Dungeon Masters, and its sequel, MOAR! Monsters Know What They're Doing, Keith Ammann reverse-engineered hundreds of fifth edition Dungeons & Dragons monsters to help DMs prepare battle plans for combat encounters before their game sessions.

Now, in Making Enemies, he explores everything that goes into creating monsters from the ground up: size, number, and level of challenge; monster habitats; monster motivations; monsters as metaphors; monsters and magic; the monstrous anatomy possessed by real-world organisms; and how to customize monsters for your own tabletop roleplaying game adventuring party to confront. No longer limited to one game system, Making Enemies shows you how to build out your creations not just for D&D 5E but also for Pathfinder 2E, Shadowdark, the Cypher System, and Call of Cthulhu 7E. Including interviews with some of the most brilliant names in RPG and creature design, Making Enemies gives you the tools to surprise and delight your players--and terrify their characters--again and again.
