All Extraordinary Combat Professions, a total of 18 series.
This includes "Gunslinger," "Fighter," "Magician," and other basic professions. Any hidden occupation is a variation of a basic profession and does not start a new series on its own. "Gun Devil" belongs to the "Gunslinger" profession series.
Any hidden occupation begins from the "Second Turn."
That is, from Level 3.
But in the early stages, a Level 3 player basically has no chance to obtain the Hidden Job Transfer Book. At this point, you're faced with a choice: when you reach Level 14 and you obtain a Hidden Job Book.
If you feel that this hidden occupation doesn't especially suit you, just sell it for money.
If you feel it's a perfect fit for you, then start over from Gunslinger Level 1, and at Level 3, activate the Hidden Job Transfer Book.
This is also one factor that widens the class gap.
