unknown hidden leaf ninja
as for cygnus knights, i believe they achieve it differently like killing a manon to get advanced combo
No one said anything about cygnus knights, but just to clarify...
Like all Cygnus Knights, to get your lv. 100/110 skill you have to go to Ereve, there you take on a quest to go to the 3rd/4th training room(100 = 3rd, 110= 4th)(the 2nd one you got your 2nd job at.) and once in there a random boss will spawn, one of four, and they are easier than the real ones. To get Meteor Shower, I had to fight Pianus, and I killed him in less than 2 min.s(not meant to brag, just meant to say how much easier they are.)
