Yeah, I know you can fight Behemoths there, but that takes forever. I've recently found out that fighting Behemoths at the End of the World and fighting Angel Star (right before Final Rest is the easiest to get to) are the only two options available. Oh well, thanks anyway.

As for Lucky Strike (I'm talking about only treasure, no HP/MP balls and Munny), even with it equip, if I choose the staff at the beginning, I hardly ever get treasures (including when Lucky Strike is equipped to all party members). Then again, that could just be my horrible luck .
