actually....I got the Actual Princess Xenthis's sword. It looks like a regular Temerian sword but the pommel is a gold crown and the hilt is gold too. Stats are 31-35 with poison 10% and bleeding 20%. It's a common class sword....big disappointment after all the mesage board hubbub. I think this last update fixed it or maybe im just lucky. But, the sword actually exists and its not some piece of crap rusty sword....I swear. How I won was I beat him with a full bet both times...back to back without leaving the conversation. first time I beat him with four 2 dice and the last time was with a pair of 4's and a pair of 3's...I think. Got the dun bannar cloak too. Sorry to everyone who isn't getting it...If anyone cares anymore for that fact.
Edit 1: And...btw, here's a link to the actual wiki on the sword http://witcher.wikia.com/wiki/Princess_Xenthia_sword
....although...the one I have IS actually called the "Princess Xenthia's Sword" but it isn't a sabre design......so the sword in the picture isn't the one I have...Stats are all the same though.
Edit2: Well...I took screenshots of everyhting...but this site won't load them.....I can email anyone proof if they want...just lemme know.
