Blueprints can pave your way to success
Blueprints are considered to be one of the most prized possessions in this game. It is not easy to collect Blueprints as they are rarely available on the map. You can find these Blueprints by decimating an Elite or a boss, or you have access to a secret location. Even if you get your hands on one of the Blueprints, it is wise to only buy the vital items.
