I have all 6 dolls, if anybody wants to borrow them, send me a friend request (Gamertag: Metacarpi UG), and a message saying you're from these forums, and I'll meet you upstairs in the Cow and Corset in Bowerstone Market.
I now have a method that takes merely seconds to achieve the Dollcatcher, and avoids the strenuous hassle of trading them back and forth. My GT is in my signature, and once again this method is, Free of charge, of course!
I have Lucien dolls (7 total from the shooting range) that I am willing to trade. I am only interested in doll for doll trades to get the achievement. I need Hammer, Garth, Theresa, and Reaver dolls. Please send me a message in game, saying you found out about me from this forum. Thanks!
