Classic Dungeon Design Guide Book III
A dungeon-design reference for fantasy roleplaying, featuring more than 1,200 room entries covering treasures, traps, magic, monsters, shrines, vaults, and other locations. Six matrixed D1000 tables generate themed dungeons from room size, floor plans, and random rolls. The guide also includes example layouts and room arrangements for caves, dungeons, manor houses, strongholds, temples, and tombs, along with themed sub-clusters such as arenas, hideouts, and haunted temples. It supports both planned design and random sandbox play.
