I haven't touched this game since last Fall. I got distracted by all the new releases, but I'm ready to finish it off. However, I have no idea where I left off or what I need to do next. I'm in World 3, all characters around lvl 45, no clue what to do next. I'm just flying around trying to trigger a plot event. These old games really are hard to jump back into once you've put them down for a bit. --- Pokemon FC: 4856 9308 0809 Name: Joel
Easy way to resolve that problem is to check your magic for the following:
Holy/Flare Meteor Bahamut Phoenix Leviathan
Each of those spells corresponds with a certain sidequest, and I think most of them give you a scroll for sealed weapons.
At any point in the third world that you have the airship (except I think you might need at least one sealed weapon scroll used) you can fly into the X-Zone near Tycoon and proceed to fight Exdeath after a lengthy dungeon. You don't actually need to do all the sidequests.
If for some other reason you can't do any of that, you might need need to go to the great library and learn about the sealed weapons.
