if someone can please pass this for me;
La la la la, patch to 1.2 or it won't work: http://www.mediafire.com/?jbmwwirg8iysjd8
Do you know where I can find one?
Not off the top of my head. I haven't actually played in awhile, sorry. I just help out with the Kayran because I'm a good-karma glutton.
When you patch to 1.2 you get the mysterious merchant DLC, and there should be a merchant across from where you get the reward for the Kayran... that guy might sell a silver sword, but I'm not sure on that.
