what is becmi d&d BECMI D&D is a classic, modular edition of Dungeons & Dragons published between 1983 and 1986, edited and expanded by Frank Mentzer . [ 1 , 2 ] The name BECMI is an acronym representing the five separate boxed sets that made up the complete game, designed to take characters from absolute beginners all the way to cosmic deities: [ 1 , 2 ] The Five Sets of BECMI Basic (Levels 1–3): Taught the core rules, focusing on basic dungeon crawling. Famous for its iconic "Red Box" . Expert (Levels 4–14): Expanded the game into outdoor wilderness exploration, hex crawling, and initial faction play. Companion (Levels 15–25): Introduced high-level domain management (building castles and ruling lands) and mass combat rules called the "War Machine". Master (Levels 26–36): Added advanced options like weapon mastery and high-stakes epic quests. Immortal (Levels 36+): Allowed characters to transcend mortal existence and become gods. [ 1 ] Key Features and Legacy The "Basic" Line: Unlike Advanced Dungeons & Dragons (AD&D) running concurrently at the time, BECMI was a continuation of the simpler, streamlined "Basic" D&D stream. [ 1 , 2 ] The Setting: It served as the primary vehicle for the classic Mastara campaign setting, originally known simply as the "Known World". [ 1 ] The Rules Cyclopedia: In 1991, the first four sets (B, E, C, and M) were combined into a single, comprehensive hardcover book called the Dungeons & Dragons Rules Cyclopedia .
