I'm about to rebirth my dancer. I've never used a mercenary before but I know a common strategy is to get higher level mercenaries before rebirthing and use them to level quickly. I'm wondering if people who use mercenaries can advise what class and level to best get? Is it better to get 4th grade fencer because they have magnum break? Or just go as high as I can? What about spearman or bowman?
Thanks!
