Dungeon Master's Kit

The Dungeon Master's Kit contains rules concerning the arbitration and administration of the fourth edition of the Dungeons & Dragons fantasy role-playing game, and is intended for use primarily or only by the game's Dungeon Master.

It is intended as a companion book to Heroes Of The Fallen Lands, which contains all of the basic rules of gameplay, and the Monster Vault, which is a reference book giving statistics and characteristics to various animals and monsters.

It contains information on the Dungeons & Dragons world, running the game, building adventures and rewards. More than half of its content was already included in the fourth edition versions of the Dungeon Master's Guide and Dungeon Master's Guide 2.
