There we go.

As soon as I saw Thunder hitting you for 100 damage I knew how that was going to end xD

See this is where your whole pick-dresspheres-the-viewers-voted-for system comes right back to bite you since switching dresspheres is pretty damn useful sometimes. Like when you have to fight elementals and you don't have any magic to deal with them. Maybe consider adding a clause for this kind of situation?

Oversoul goes by species. You'll keep encountering oversouled elementals until you kill one. That one fight where the Red Elemental was the one that oversouled might've been a good opportunity for that, actually.

Sure, let's forget that the White Mage has Vigor for instant self-healing. Would've saved you a lot of trouble^^ Learning Reflect might be a good idea too.

Oh and of course simply equipping the Thunder Spawn GG would've trivialized everything. I seriously recommend making use of those elemental GGs (and being flexible in switching it up depending on the circumstances).

Goddamnit Flee, why must you be so terrible. Escape is always the safer alternative since it's instant. I guess it's good if your other characters are charging up something big when you decide to flee, but let's be real, how often are you gonna encounter that situation.

In all fairness, you had a pretty terrible dressphere setup for this particular mission. Two physical attackers with horrible magic defense and a White Mage. Ironically the Songstress probably would've gotten you through the troubles just fine. Matador's Song + Samba of Silence ftw.

Well, good luck on the return trip. Hope you don't run into any Amorphous Gels! ...you probably will though, since that crystal path is murderous sometimes. Good luck with that.
