In Crown of the Gods, groceries are sold in your own castle market. There are other groceries that can be exchanged for items at the Sailing Festival, and excess equipment can be broken down in the blacksmith shop. The Sailing Festival is held in every country. The items produced and the needs of the Sailing Festival in each country are different. You can check which country needs it based on your existing items, and go there before the Sailing Festival is held. Exchange with countries in need.
In Crown of the Gods, the blacksmith shop will be unlocked when the castle reaches level 2. It is recommended that you do not follow the main plot all the time. You also need to complete additional side tasks, so that the castle level will rise faster and the blacksmith shop will also Unlock faster.
The blacksmith shop is a place where equipment can be crafted and disassembled. The blacksmith shop can also be used for the furnace and modification of equipment. Through modification, the attributes of the equipment will become more flexible and can meet the combat requirements of the knights in a more diverse way. As the level of the blacksmith shop is upgraded, the success rate of making/strengthening/modifying/recasting equipment will be higher.
