The B/X Player's Guide contains all the information needed to create and run a character throughout the BX RPG—a game of monsters, treasures, and heroic deeds. It includes rules for characters up to 18th level as well as spell charts and descriptions, weapon and equipment tables, and complete character class descriptions. In all, there are 14 character classes in the game (and yes, race is class). Rules for every facet of your character are included.
To play the complete game, the BX Dungeon Guide is required.
