Well I want a Horde of Homolunculi for the purposes of crafting. In terms of RPing off the exact books this can TOTALY go awesome. Thanks for the idea of binding the Homoluncili to followers. Clever idea. Also clever idea.
OK, so here are some of the results of my theoretical experiment:
It took about a year of my 5th level character working (With a startup sum of 10,000 gold coins), but I ended up making a sweet startup Magic Item-torium.
It generates 16.7 GP a day, or 501 GP a month . This was in addition to a personal area that I pimped out for myself, and a solid starting crew. This took me about 8,000 GP to make.
It still cannot sufficiently run itself, so I spend another 6 months working there.
I increase in size. I need more labour, so I create a larger clockworkorium, and hire many more people to staff it.
Cashflow increases to 24.1 Cash a Day. Or 725 net gain of stuff a month.
Now I leave it alone with a manager; Partner. That takes down my daily earnings to 20.1 cash a day but thats cool with me. I tell them JUST to generate cash, to prevent capital attrition, (I mean even with it its still then a net gain of resources). At this point in time it can continuously grow without requiring adventurer money, and I prevent attrition as long as I immediately spend the resources to build stuff.
Overall I still need more cash, but this was just with the starting seed money of a level 5 adventurer. At level 10 the earnings are scary.
