How far can a Db go without mastery books? I made a Dual Blade once it was newly released and bought a few mastery books from the cash shop, which is still possible of course. I deleted that Dual Blade quite some time ago, and now I am unsure of how far it could go without the Master books. So my question is, how many levels and how many job advancements can I do before I am at a halt in the lack of a mastery book? Can't afford NX until end of month, hence my question...
