Game Masters and players alike are familiar with dragons and the threat they present in the world's most popular tabletop roleplaying game. They've become so well-known, however, that some might say the magic has worn off them a bit. Even the latest dragon-centric gaming supplements have simply diluted their awesome, alien presence by revealing (almost) everything there is to know about the creatures. In The Game Master's Book of Legendary Dragons, readers will find more than two dozen truly unique, epic beasts, each of which comes with a complete backstory, a history, motivations, lair actions, legendary combat actions and more. These creatures are designed to be a worthy focus to any campaign, whether as a mind-blowing BBEG for a unforgettable, high-level climax, or as a motivating force that runs in the background of a lower level adventure. Game Masters will also find new dragon-kin, wyverns, drakes, kobolds and dragon races, plus new dragon-related organizations, skills, classes and magic, including dragon riders, dragon hunters, enhanced spells, aerial combat and airship options, dragon cults and magic items, plus three incredible one-shot adventures and a foreword by Luke Gygax, son of D&D co-creator and RPG legend Gary Gygax. The Game Master's Book of Legendary Dragons will provide endless ideas for Game Masters and countless hours of epic-level fun for adventurers willing to test their mettle against the baddest beasts the game has to offer.
