Sub Job only gives Job-specific command menu? What about Specialities?

[Keytee Tamira]

I wonder if i get anything else from Sub Job.

You do not get the specialties by default.

However later you might find some passive abilities to enable the sub-job specialties. Likewise one job has a way to use its sub job specialties using its own specialty.

Note that with some specialty like the beasmaster or freelancer one, being able to use them on another class enables game breaking combos but the job system is made to be abused in this game anyways.

Chapter 3 jobs spoiler : Spiritmaster learns a passive which allows your subjob's first specialty to take effect. Swordmaster's second specialty enables both of the subjob's specialties as long as you dual wield weapons from the same weapon type.

Chapter 6 spoiler : There is a 24th job, unlocking pretty late, that learns a passive which allows your subjob's second specialty to take effect.
