Alright. Got the airship. I wish I had the guts to level up by killing the Eye for 3000XP shots, but even if I go out and get a PRoRing first, I'm perfectly susceptible to reaching lv 40 or something, proudly marching to the exit of the cave to hit a sorceror random encounter and then get fried in a second, losing everything.

What? YES! THAT'S WHAT HAPPENED!
(SPOILER)Well, I didn't exactly level THAT much, but I levelled a little...

Anyway, I am faced with a tactical problem.

The nature of this challenge is not only difficult in that I am playing with the least adept killer in the game, but also, as with all solos, that it is kinda cheating to use the weapon slots of my deceased friends for storage.
I can't risk opening the wrong treasure chest and picking up an item that I don't want now, but will need for a later part of the game.

Now, I'm going to Ordeals right now. And then, most likely, to the Waterfall. When I'm done, this will be my gear:
Dragon Sword, Heal Staff, Defense
Gold Bracelet, Ribbon, ProRing, Zeus Gauntlets

Then I'll go after Kraken. In Kraken's Lair, there are 3 items worth considering in my inventory.
Light Axe (Screw it. I'll have a Mage Staff)
The Mage Staff
Power Gauntlet

I'm going to want to Power Gauntlets, but I don't quite see any way to carry them, since I'll need Zeus to kill the water monsters.
Bah! This isn't too hard to figure out. I'm not going to get any of it.

When I hit the sky castle, I'll replace Zeus with the Black Shirt and pick up a Bane Sword, wish that I had room to carry a ProCape, and then the game will be all but over.
