xD There's a little treasure chest after Abductor if you manage to beat it xD
Chapter Whatever- A Brave New World:
On what is commonly referred to as "World 2" (because square didn't really give it much of a name other than "galuf's world" you will run into precisely one enemy, which drops precisely one item, and lenna keeps having a cutscene where she urges you to use a tent. If you have plenty of tents, go ahead and use one, else fight the encounters to stock up!
When you use a tent, a cut scene will activate where the sisters are talking, but then they're abducted! An abductor comes for Bartz. You don't have to win this battle, but there's a cute little scene if you do
Afterwards, your party ends up in Exdeath's clutches, and the warlock himself sets about breaking numerous laws of physics, mainly those of Optics and how mirrors and lenses work. Ugh.
Shortly, you end up with control of Galuf and all your equipment (it was lying nearby in a handy chest)
If you would like to save or heal, head out the door to the top. There will be a save point and past that, a healing pool. The door at the bottom is locked, so when you get done saving/healing, head to the left and out that way. The next room only has one exit, at the top left corner.
This next room has our friend Gilgamesh standing in it. As you approach the center, make sure you're healed!
GILGAMESH:
He has nothing to steal (this time) so don't worry about having a Thief or Steal equipped. A heavy physical attacker with some healing will do just fine with him (I used a Ninja with Jikuu if you can believe that. Haste+Regen+2 moonring blades)
He has a hit for about 100-200 dmg, so with only one target, that starts adding up pretty quick, but he can't stand very many physical attacks!
After that, you regain your party, so it's all groovy. There's not really any where to go from here, so head back the way you came. Bartz does some crazy floor crawling when you go past the prison cells xD You can exit out the very bottom door in the first room, and voila, world map!
