Trade
You can buy and sell supplies and treasures from merchants.
The number of goods available for trade is fixed and changes with the seasons (in January, April, July, and October).
Select Council > Trade from the command menu.
Market Price
Market prices may change depending on certain factors, such as the season, a bountiful harvest, or a famine.
Treasure
You can buy treasures if the merchant has them in stock.
Purchased treasures can be gifted to officers to increase their loyalty and abilities.
Treasures can also be presented to other clans during negotiations via Tribute to earn temporary favor. They serve as negotiation offers during direct talks as well.
*In order to purchase high-grade treasures, you must complete the Total Commerce clan target.
