At the starting of the next area simply follow the bridge up and kill the trash Blade and Soul gold mobs. You will encounter a force blader. Note that he will windwalk away from you when he’s down to around 30% ish hp. After this the next mini boss will become active:
Whipi is pretty easy to Blade and Soul gold kill. His aoe skills are very easy to dodge by simple movement, kill him and then carry on moving forwards.
Wun Gwangyi is a Blademaster so she possesses the typical Blademaster skills such Blade and Soul gold as block & a few aoe’s. Her main skill is a charge up aoe (you will know when you see it) which can deal a lot of damage so be sure to try and stun her before she gets that off.
Remember the 2 force bladers that ran off? Well, here they are guarding their Blade and Soul gold captain. I like to kill them first as they can be quite annoying. Wun drops similar loot to the first main boss.
