This book does as promised adds new rules. There not bad but compared to Deeds and Glory they just don't add enough to really enhance the core rules. The dungeon scenarios are cool, I just don't feel that they fit the wargame genre.

Song of Gold and Darkness is an expansion for the miniature skirmish game Song of Blades and Heroes. It adds a number of new abilities, new creatures, rules for terrain and a new "game mode": dungeon exploration. If you liked the basic game, I believe that this book is worth, even if you don't plan on playing in dungeon maps. The only down side are the solo dungeon rules, which I think could have been a little more detailed.
