One of the issues people have with Final Fantasy II is that its progression system can make it a little tricky to determine what “level” you are.
This means it can be quite easy to go into a new situation either woefully underpowered or vastly overpowered — though let’s be honest about this, the latter option has always been part of the fun of role-playing games, hasn’t it?
At this point, an encounter in Leviathan’s stomach on the way to track down the Ultima Tome would seem to confirm that yes, indeed, we have taken the latter option. Oh well. No turning back now!
