It's a new Adventurer. And it falls under the Rogue category class. Probably you will need to play a beginner > Rogue > the new Dual Blades Job just like any other adventurer. Since most adventurers got 3 classes (eg:Warrior: Fighter, Page, Spearman. Mage: Cleric, I/L, F/P), it could be Thief 3rd class. Oh yeah, did i mention that the new Job will have 6 Job Advancement instead of 4. And it have it's own Cash Shop just like the KOCs and Aran. Gee..So weird.. just imagine..

As i said before, the new job is not even out in the test server, so everything i said here couldn't be confirm yet till the test server patch is out.
