Wally DM's Journal of Puzzle Encounters

A collection of 60 puzzles for fantasy role-playing games, designed to add mystery and interaction to dungeon encounters. Players may swap gems in an owl statue to open a door, turn a hand to stone to unlock a portal, or taste a cube to determine whether it is bitter or sweet. The book also includes a table of 100 unusual rooms for populating dungeons. Each puzzle can be used as written or adapted as a starting point for custom encounters.
