limit 3-2 from here just give her the lvl 4
Hope this helps, and i found that the best places to lvl are in the Cave of GI and Mt. Nibel(in the room with the materia keeper), because a group of monsters can give up to 3k xp and up to 300 AP (which is 600 with rune blade, drill arm, etc.) and for the dragons you fight in Mt. Nibel(in the room with the Materia Keeper), you can use lvl 4 suicide (enemy skill gotten early in the game, u can go back and get it if nessecery) and it will bring him from 3000hp to 48hp :). You can also Steal Gold Armlets from these dragons. As for anything else, by this time you should have lvl 2 magic and at least lvl 3 ALLs(which should be combined in your "armor" slot, since there arent any "double" materia growth armors at that point. Have any armor besides Edin Coat, Mage Armlet works great, as well as gold armlets, or carbon bangles), so simply cast bolt2-all or fire2-all (ice2-all works too, its just not as effective[bolt3-all is possible if you used force stealer the whole game and had double, which is what i did and i had bolt 3 by the time ) until the groups have been vanquished. Training in this area brought me from lvl 31 to lvl 36 and my Aeris from 25 to 32 in about 10-15 minutes, so this is one of the better places to train, especially right before you go and fight the Red Dragon and the Demon’s Gate.
Hope this helps you get Aeris’ limits, even though i myself havent XD
-=((Side note))=- With my char.s at this lvl, and having bolt 3, big guard, white wind, and aqualung, i beat Red Dragon in a matter of 5-6 turns, and demon wall in about 10-15 turns.
