What is the monetary system of Loki's heroic biography?

The war currency system is a special navigation system before the revision of Loki the legend of heroes. It needs war currency to enter the copy battle. War currencies are divided into gold and silver, and the cumulative number of voyages of silver war currencies gradually increases the number of war currencies needed for navigation. Gold coins do not count the number of voyages and increase the experience gained in the campaign.

Now the game has replaced the war currency system with the fatigue system, which has advantages and disadvantages, so I won't point them out one by one.

Hope to adopt!
