The only problem is that meteorrain does so much less than what you'd expect, or what the official guide estimates.

I lvl up in the reactor until I run out of potions. You can't use inns or the restore materia, yet. So I haven't been able to get meteorrain yet at the reactor. Fort Condor is some place where they let you rest for free, you can use hypers, and those things in the forest build up your limit quickly, and they're in groups, so that would be a nice place to do some limit building.
