Tricks, Empty Rooms, & Basic Trap Design

A toolkit for creating dungeon rooms beyond monsters, treasure, and conventional traps. It provides structured tables and guidance for designing empty rooms, special features, tricks, and basic traps, helping gamemasters generate meaningful details and encounters for large dungeon environments. Rather than combining random elements without context, the system categorizes the ways a room can be empty or unusual and offers frameworks for developing them into coherent scenes.
