Yeah, once you got your steel armor, money is purely for high level magic, and even then there's enough cash in treasure chests that trying to get money is rarely a problem (FF1)

Try FF3j. At the end, you can buy Shurikens for your Ninja class, and they can do all 9s. But they're 65k a piece. Needless to say, if you have money, there's no reason to because it's always better to have more shurikens.
