elite quest

Elite quests are harder to pass than the common quests. Every time you defeat a BOSS in the elite quest, you will get a Blueprint (BP) for equipment. Each BOSS can only be defeated once a day. But you can buy more challenges to BOSS by becoming a VIP player.

Click Elite Negotiation on the upper right to enter the interface of elite quest.

You can also Sweep in the elite quests to finish faster.
Before sweeping, you will see the time to be cost to sweep the current quest and the target to be swept and also the bag slots left, which makes the operation very easy.
Only the elite quest that you already passed can be swept.
