I've just started the level one Ozma challenge and I figure since I can't fight battles for a while, I should be able to gain money by equipping Flee gill. However, when I run, it seems like I am the one dropping money, and not the enemies. How exactly does flee-gill work? How can I go about running from battles without losing my precious money?? (I've never ran from more than one or two battles before until now, so I didn't even know that I lost money from fleeing.)

Yeah, so how exactly does this work? What do I have to do to get Flee-gill to work? (Yes, it IS equipped.)
