Dual Blade Mastery Books

Newly created Dual Blades can receive free Mastery books from Lady Syl for their 2+ through 3+ skills. These skill books expire in 30 days. The quest can be accepted from a light bulb notification above your character’s head or from talking to Lady Syl in The Secret Garden.

Just wondering which skills are 2+ and 3+, and then also what mastery books still need to be purchased?

I think it's just the 4th job skills you have to buy now.

Don't those drop from monsters / come from mystery books like every other 4th job book?

Anyways, I'm going to make a Dual Blade (already planned this when I heard about the free books in KMS) because they're one of the few classes that uses all their skills (and has skills beyond "Single Target, 6 Mob, Rush, Ultimate and Buffs" to use). The fact that 3rd job no longer requires Dark Crystals is great, too.

Oh nicee Thanks for the answers.
