From publisher blurb:
The Elixir of Kosomodes is a level-1, city-themed, fantasy adventure for 6–8 characters for the Dungeon Crawl Classic Role-Playing Game inspired by the classic 1950s sci-fi thriller Invasion of the Body Snatchers.
Designed to drop into any fantasy city setting with little or no adaptation, it works equally well as stand-alone, one-shot adventure or as a segue between major episodes in a campaign.
Included with this module are instructions for running a physical representation of the adventure's main puzzle that allows players to mix real-world components and craft their own elixirs at the gaming table.
Lost in an unfamiliar city, you take refuge in a run-down merchant district only to discover its taciturn townsfolk have been surreptitiously turned into emotionless automatons. And soon, you too are targeted by the mysterious machinations of otherworldly invaders.
To uncover who (or what) is behind this insidious plot, you must first solve the puzzle of Kosomodes’ elixir.
And you must hurry....
For the invasion has already begun!
