Evisceration only. Element type doesn't matter, but slag would be amazing. I don't have much to offer as all my guns are under 61. The only thing i can think of that I could trade is the frozen wrath skin for maya. Or any other skin from BGH. (except axton's)
I'm about to be 61 and I already did the mission to get Rubi so I kind of screwed myself. Just hoping someone is kind enough to trade/dupe it with me.
