Item Exchange Center
Item Exchange Center is now in OPTS!
You can access it by clicking the diamond icon in the Plaza, and trade Diamonds for various goodies such as character medals, All-Medals, 7* Char Medals, and 3* Special cards. Note that some items have an exchange limit (e.g. 7* Char Medal). The available items will change from time to time.
The exchange button says “Remaining: 1”
Diamonds will be given out as rewards from clearing quests and missions (e.g. Challenge Quest). To celebrate the launch of Item Exchange Center, players will receive a total of 20 Diamonds over the next 10 days as login bonus. You can hold up to 9999 Diamonds at one time; any excess Diamonds will be discarded.
