Quick Leveling

[Morbid]

For just pure XP grind for battle classes I suggest doing fates both at and 2 to 3 levels above you. XP comes much faster, less delay in between and it doesn't cost you 'tokens' / leves to spam them for a couple hours.

Match this up with running the dungeons right when they open and you'll fly through the first 25 levels or so. If in a FC Battle Ready II and Brave New World II buffs make this even faster.

I also suggest saving up a full catch of rest XP before starting the grind. Just stack as much xp bonus as possible even using weak foods since they still give the same 3% bonus.
