Editing Dwimmermount: If Trouble Was Money (section)

=== Banking and Money Transport ===
*You can change GP into gems and jewelry for a 5% surcharge. So, buying a 100gp gem costs 5gp, or a 1,000gp gem costs 1050gp. This is something you pay at the time of purchase.
*You can also get bank notes, which are bearer paper. The available denominations are:
**1,000
**2,500
**5,000
**10,000
*Both are most likely to be available in larger communities. You're going to have trouble making major transactions in Muntburg, although Adamas can accommodate large purchases of gems and plenty of movement in bank notes. 
*Bank notes need to be kept in a scroll case, which counts as a Thing, but you can fit a fairly large quantity of them in one case. 
*Also, they are not totally risk free, in that sufficient reversals of fortune among the merchant houses could result in the money being lost. On the other hand, there's no fee.
