Aah, Zanarkand, the place where my infameous expspamming was. I was so bent on getting Lv. 4 Key Spheres there, and Lv. 3 so much I finished their normal routes easily, and get on to another ones, and finished them as well, all to get those Key Spheres and special weapons
Since I was getting a lot of Exp in Bikanel Island, I was catching monsters as soon as I entered Calm Lands. I catched all of them, and rest of the fights was simply going through the Cave of Fayth to get Yojimbo, and Gagazet was all catching monsters in the process. That really sped up some things.
