From the publisher website: Steel and Glory, Magica is an expansion for the Steel and Glory game system. Now you can add magic to the mix and watch as the battle changes. Within you will find two new characters for each faction, rules on casting spells and a ton of magic cards to cast while your forces battle their foes on the fields of battle. This expansion is not a complete game, and you will need one or more of the Steel and Glory game sets to use this product.
