Wallenstein's Contracts is a technology in Age of Empires III that is unique to the Germans and can be researched at the Church once the Fortress Age is reached and the Treaty of Westphalia Home City Card has been sent. Once researched, it reduces mercenary cost by 15% and train time by 10%, and also halves the coin cost from German Home City mercenary shipments except infinite and TEAM cards.
