even though i must point out that in the original you got 0 information even after buying..
you always had to use magic to get to know the stats...
It's kind of a roleplaying dilema. When you buy a weapon in a real roleplaying P&P, you wouldn't get to know values either. Since there is a wiki planned, that should be a reasonable solution for both, the player who wants to know values and the one who claims they destroy atmosphere.
