How much wealth you are able to trade with your friends has been made more generous. Exactly how much depends on how long you’ve been friends (i.e. how long you've been on each other's Friends Lists).
If you’ve been friends for at least one month, your trade limit will be doubled; for two months your limit is tripled; and for three months your limit is quadrupled!
As before, when trading, you will continue to be limited by whomsoever has the lower trade limit, but remember that you are able to increase your trade limit by earning Quest Points.
