From publisher blurb: Welcome to Advanced Olde Swords Reign, a tabletop roleplaying game with modern mechanics taken from the 5E SRD (System Reference Document) and based on the original 1974 edition and later Advanced Editions of the World's Oldest Roleplaying Game and some of those editions supplements. It is not a retro-clone but more of an homage to the "old-school" style of play that is more readily accessible to modern gamers. Rules and Magic is filled with over 300 spells, 12 classes, 7 races, feats, backgrounds, rules for combat, and more.
