Okay, I have a number of options for use of the money! Hoard it, so I can feel good about myself. Find some way to spend it on Concordia. Though I already have all the supplies I need. Buy a set of god armor, a god bow and a god sword, and kill minibosses and Enraged mobs on difficulty 7. Sell the drops for a profit. Invest in a business for a profit. Already paid AlarmGoesBeep 15k. Whether I see that again, time shall tell.
I do number one just generally because I hoard everything Though, number three sounds fun, because #Fragments! #DSFAM
