It’s relatively straightforward in that sense: the more coins you earn, the more rewards you can receive. There are several ways to earn coins. For instance, every red ticket you use will give you one coin. Every precious mount box opened nets two coins. Using a Red Phlogiston in refinement gives three coins. An Azure Ticket gives three coins as well. Opening a Spirit Feather Box gives you four coins. Using a Red Phlogiston in refinement earns you nine coins. And finally, using a Large Sacred Object Treasure Map, Enchanted Treasure Map, or Spiritual Object Treasure Map will give you 28 coins.
And what can you earn with those coins? Turning in those coins will net you the following rewards:
- 35 Coins: White Jade x25
- 70 Coins: Exquisite Synergy Horn x6
- 200 Coins: Azure Ticket x10
- 350 Coins: Advanced Skill Key Chest x1
- 550 Coins: Serevar - Elite Enchantment
