Super early game:how do you make money?
Beat random NPC's up, take all their shit, sell at appropriate stores in the mall.
The moment you get a slaver's license:
Enslave NPC's and sell them at the slave market. Best targets are slimes in Submission. They're not difficult to beat. You can order them to transform into whatever you want (dragon-morph is most valuable as far as I know) and then you can enchant a biojuice cannister that they're probably already carrying to make them flesh. They sell for like 100k a piece if I remember correctly.
