You get 2, and you always choose Mastery first and AFA second. For any class that gets a mastery in 4th, it's the first skill you should be maxing, AFA being 2nd or 3rd, depends on if you get skills like buff mastery or w/e, and if that's the better choice since they are only 10 points anyway.
Now, if I could have only chosen one, I would have gone with AFA, cause it's generally more expensive.
- Mihile can obtain untradeable Special Mastery Books upon reaching 4th Job Advancement. - Accept the quest through the event notifier on the left side of the game window. - The books are as follows. All of them have 100% chance to raise the master Level of their corresponding skills. - Expert Sword Mastery 30 - Advanced Final Attack 30 - Soul Asylum 30 - Special Stance 30 - Roiling Soul 30 - Four-Point Assault 30 - Radiant Blast 30
the above update notes did not say that mihile could only get 2 books, one at level 70 and another one at level 120. in other update notes for other jobs, nexon specifically mentioned the books that a character can get and at what level. in the above note, nexon said that "mihile can obtain untradeable special mastery books" and further said that "the books are as follows." then nexon mentioned the names of the books. nexon did not say that mihile can only choose 2 of the 7 books mentioned.
nexon should have stopped at the second line [should not have listed the names of the books].
When the going gets tough, they call on the sons of ******s.
