Dungeon Master's Guide: Core Rulebook II (Dungeons & Dragons)
Like previous editions, the 3rd Edition DMG further explains the rules introduced in the Player's Handbook.
But this book goes beyond rules and offers valuable tips on pacing, story
creation, conflict, villains, motivation, and player rewards.
Novice DMs will benefit from the sections on creating individual adventures and describing
action, while even experienced DMs will appreciate the notes on extended
campaigns, detailed world creation, and high-level play.
Well-considered optional rules are offered to daring DMs, including rules for monsters as PC races. high
technology, and guidelines for creating custom races and classes. The nuts and (lightning) bolts of DMing are also covered in great detail.
Artwork, examples, and diagrams are liberally placed throughout the book. All this attention to detail makes the
DMG an easy and effective read
