Final Fantasy XII, Leveling Up.?

Question

Ok. Hi. On Final Fantasy XII I want to level up Fran, Basch and Penelo. So far Vaan, Ashe and Baltheir are level 99, but Frans level 25, Penelo's level 55 and Basch is level 64.
And I forgot how I trained Vaan, Ashe and Baltheir. So I want to get them all to level 80. Any ideas?

Basch will weild Masamune, Fran will weild Fomalhaut and Penelo will also weild a Fomalhaut.

Thanks!

EDIT: I mean I want them all 80+

Answer 1

First, equip your lower level party members with the Embroidered Tippets, so they get double EXP. I've found the best place to accumulate mass EXP is the secret area of the Henne mines, which can be unlocked by the Geomancer in Jahara after you acquire 10 espers, but this may be too tough a place at your current levels. Other good leveling spots are The Necrohol of Nabudis, the Nabreus Deadlands, Giruvegan, and the Pharos at Ridorana.

Answer 2

Ok, since you are already in Giruvegan, this is a pretty decent place to level up for the level you are now. Equip those Embroidered Tippets, you will receive double EXP. Do you have the spell Bubble or Bubble Belts? Bubble doubles your HP, and it is so helpful. Also, if you can survive it, the Necrohol of Nabudis and the Nabreus Deadlands are good leveling spots too. There are even better leveling spots in the game, but I don't think you would survive them at your current levels. Good luck.
