This is the Dungeon Master's Guide for the 5th edition Dungeons & Dragons roleplaying game. As the Dungeon Master (DM), you lead a party of adventurers through a story-driven, tabletop game, and this is the book you need to do that. Inside you'll find world-building tools, tips, and tricks for creating memorable dungeons and adventures, optional game rules, hundreds of classic D&D magic items, and much more!
The Dungeon Master's Guide is the second of three D&D core rulebooks, along with the Monster Manual and the Player's Handbook.
