Q: How do I open an instance? How many times can I challenge an instance each day?
A: Players can enter instances through the instance entrance. Challenging instances or sweeping instances requires a certain amount of Stamina. When you don't have enough Stamina, you will no be able to enter an instance. Stamina can be obtained through the Treasure Trove or the Shop, and a certain amount can be collected at fixed times.
Q: If I quit an instance mid-way through, can I continue the challenge?
A: If you quit an instance, the system will not save your progress. The instance will reset, and you will still lose your Stamina.
