I have to spend a lot more time running errands in FF3j, mainly because luck is so difficult to manipulate in this game. A good example is me grabbing the Ice magic in Sasoon Castle before I enter the Cave of the Seal. It took a lot of time, but it was necessary. This run will definitely be longer than FF1.
EDIT: new WIP--this time, I exit Bahamut's nest. Not much progress, but I managed to get one extra level up required to cast lv. 2 magic. I still need one more to get a safe margin for Big Rat, though. Just one cast of lv. 2 magic won't be enough, even though I still have two Southwinds and one Zeus' Rage.

EDIT: updated first post. Please suggest things for version 2 if you have any ideas. :) (Version 2 will be when I restart the entire run from scratch to perfect it--this current version is mainly for experimenting and finalizing the route.)
