Those drakes can be easily avoided though, as well as Mega Tormberrys. You don't HAVE to fight till lvl90+ (I think) and at that point you can run from the fight.
Cloister don't appear constant in every files. If you found any Elder Drakes, just get out of Via Infinito and enter again, you can get an easy map or harder, if you get harder one, get out again and enter back!

I think there are floor where you must fight Mega Tonberry in order to pass or to get out. I found it in Cloister 80+. And be sure to level up in Via Infinito, when I first entered Via Infinito, my party level is 70, at the end, all of my members level are 95+.

Once you got Cat Nip, you can fight against all monster easily, except for Mega Tonberry because they might attack your Cat Nip'ed character. All strong monster are capable of beating your Cat Nip'ed character in one hit but all of them are slow except Chac, Mega Tonberries and Trema often kill your character faster and you really need Mega Phoenix to revive them.
