I didn't know this was a GM Event item! Nice. Mine was given to me by a friend, Germania.
The stats are good except you have to take it off to buy/sell because of the -10 CHA. It'll make the prices a bit higher/lower and in some cases can determine whether you get 9gp 7cp or 1pp 5sp for something sold to a vendor. Not much but in my opinion it's worth it.
