Infinite Gold 

To do this trick you need Philia to be at a high 
enough level to have the special that acts as a 
R.Bottle. Go to a place that sells apples, buy as
many as you can, then use that special to turn

TIMES AS MUCH as much as apples. Sell those off 
and buy more apples. Repeat as desired.
