stop leveling? I wanna level as much as possible before its necessary to buy any mastery books, but it seems Ive hit a wall at level 45 because I cant make the advancement unless I dropped points into fatal blow (which I assume is a bad idea?). So do I stay at 45 then until I get slash storm upgraded?
You have to put points into Fatal Blow, even if you have mastery books. 8 minimum (recommended) to continue, but as garudamon said, you will not be able to do 4th job advancement at all if you do not have the required mastery books.
