I think that what helped Bilbo was dispersing the gold, in the same way that Tom B. spread the treasure from the Barrow out in the sun to disperse the curse.Summerhawk wrote:As for curses, I'd say a curse of weakness (Dragon-sickness) would be likely. And you're all right, the idea of using it for good is probably unlikely as it would have a lot of darkness to it. The player heroes have good intentions with it, but it will probably lead to trouble.
On the other hand, Bilbo's generosity with his dragon gold seems to undo much of the curse, so there is an interesting question about how much good intentions make a difference with cursed items.
So feeding the scale through a paper shredder and spreading it to the four winds might work...
