Along with the Player's Handbook and Dungeon Master's Guide, the Monster Manual is one of the three 'core rulebooks' in most editions of the D&D game. Creature descriptions include game-specific statistics (such as the monster's level or number of hit dice), a brief description of its habits and habitats, and typically an image of the creature. The Monster Manual was the first hardcover D&D book and includes monsters derived from mythology and folklore, as well as creatures created specifically for D&D.
The Monster Manual ( MM ) is the primary bestiary sourcebook for monsters in the Dungeons & Dragons ( D&D ) fantasy role-playing game, first published in 1977 by TSR.
