Monsters' Lairs vol 1: Goblins' Caves

From the Introduction: "The Goblins-Caves" is a description of a generic location you can place in any classic fantasy setting. It's not an adventure but it contains ideas for dozens upon dozens of adventures. You can pass through the goblins' caves by hack and slash, but it's much easier using reconnaissance, knowledge and hit and run tactics. Additional User Summary: The supplement includes a detailed map of a goblin cave complex and environs. Key encounters are provided using D20 stat blocks.
