Increase drop rate of skill up items. I tried for a week straight faming them in Z Mines, and never saw a thing. Was a waste of time.

Also, on the skill up note, can we get an official description of what the skill up foods do? After all this time and testing form the players, their is still no official conclusion. Their are a few prominent theories, but nothing concrete. (And I'm tired of hearing someone from each theory swearing they are right and damning everyone else) So an official declaration would be nice
