I'm not quite finished yet, but I still have in excess of 40,000....
Cespenar's upgrades are a fantastic way of getting rid of the money bags, but at this point in the game after SoA, money really hasn't been an issue for me with the rampant amount of magic items around.
If one uses a bag of holding to materialistically and methodically pick up and store every magic item, then I'm sure you could reach the ridiculous fortunes that Dundee mentioned. [img]tongue.gif[/img]
