I'm level 68 and on the moon with the only summon missing is bomb. I am going to attempt to do this at end game or at least until I hit level 99. It amazes me how Final Fantasy games can keep me playing so far after I reach max level. What I am going to do is do the max stat trick once I hit level 70. You got 9 various level ups which you can gain at level 71-99 and I plan to get the best stats. This shouldn't take too long.
