There is an armor that looks very very much like an enigma dusk shroud i think. One of those light armors. Basically the person puts it on and off and on and off of the trade screen. (the enigma). Then when hes finally ready to trade he puts something that LOOKS like an enigma, but isnt. YOu end up trading thinking it is the enigma and you get scammed. I hate fucking jackasses who do that.
