Hello, good morning/afternoon/evening!

As the title says, I would like to be able to buy Temporal Spells with Instance Coins. I think it would be very helpful for some characters who have difficulty soloing the boss.

Thank you very much!

The difficulty of soloing the boss is momentary. When you least realize it, you will hit the MVP and he will die. In the meantime, help maintain the market and buy from the players. :
