Note - this mission cannot be completed without the New Fei'Yin Seal.
Form a level 50+ party. You may use anyone from any nation currently on Mission 5-1, as it is the same for all 3 nations.
There is no longer a level 50 cap on this mission.
Even if you've done this mission before with another nation, you must be on this mission or higher in your current nation to help others (otherwise, you will see "A mysterious force is sealing the platform.").
In Fei'Yin, head east towards (K-8). At (K-8) you will see 2 dolls. There is a cermet gate on the east wall. Click on this gate to enter Qu'Bia Arena. The majority of the monsters in Fei'Yin detect by sound, but there are several monsters that also aggro to magic, so Silent Oil is recommended. If you have been here before and checked the Home Point outside of the BCNM area you can just teleport here.
