Campaign Builder: Dungeons & Ruins — D&D 5E Dungeon Design Guide

The dungeon is where legends are made — and Campaign Builder: Dungeons & Ruins gives you everything you need to build ones worth remembering. This is the ultimate dungeoneering toolkit for D&D 5th Edition, covering dungeon design from first principles all the way up to full megadungeon construction.

Whether you're dropping a single trap-filled vault into an existing campaign or building a sprawling subterranean complex that will anchor an entire arc, this book has the tools, tables, and player options to make it sing. Compatible with both D&D 5E and Tales of the Valiant.
