A miniatures game that, on a statistical basis, faithfully replicates the results of combat in the Original RPG on a mass scale (with each figure representing 10 troops or 1 hero). To resolve attacks, each figure in a unit that is eligible to attack rolls a D6 against a target number to determine if it inflicts casualties on the opponent. A unit receiving casualties must then succeed in a morale check or rout. Rules are provided to convert troops and heroes from the Original RPG's statistics to Book of War. Magic rules derived from that game are also included.
