There are a few socially dependent adventures within wfrp and they require a certain amount of cash, noble status and all the lovely craziness that goes with it. So I was thinking about putting together a faction sheet or something similar for that most dreaded of institutions, your bank.
So far it's looking like this:
Banks have two tracks, essentially credit and debit.
Credit tracks your money going out. Generally, this allows you to essentially ignore silliness like brass and silver and focus on the big league, but if your loan is big enough, you can even ignore expenditure as high as five or ten gold crowns a week. You can make a large purchase and move the credit track down, to represent you swinging your coinpurse about.
Debit tracks your money going back in. This is your track on how long it will take you to pay your money back and how much of a squeeze the bank is putting on you. You can borrow a certain amount, based on your social status, and that amount can "stretch" based on your noble rank and other factors. When you begin to borrow over this however, each point you are "overdrawn" counts as permanent, unremovable stress, as the bailliffs knocking on the door start to worry at the back of your mind. It also downgrades your noble rank for the purpose of social combat; noone wants to be seen with a defaulter.
There are a number of ways you can bring the debit track down. One is to make an education roll based around investment and then make a "finance" roll. Success means you've rubbed two crowns together to make three. You may adjust your track based on the results. Another is to be the life and soul of every party in town. Lenders love giving money to social climbers like these, as they can rely on that person being in their pocket for a long time into the future. Of course if they lose the run of themselves…
Finally, there are several types of bank. Some are legit, dwarven lenders are well known for crossing every t and dotting every i. They are difficult to appeal to for cash, but when you get it, oh boy the repayment period…
Some are not so legit. Certain Tilean families of questionable reputation are well known for how quickly they will gladly throw out gold crowns. Of course, they demand repayment quickly, but don't worry, if you can't make your payment, there are always a few "favours" they need done…
