Just returned again, and was reading the update 50 stuff. I have a sword of shadows (and some other VON stuff), but everyone says if you can only have 1, keep it heroic (butwith new system, I could upgrade it). My question, are they still unique? Can I use my SoS to farm for a second, so that I can have one to upgrade, or does it have to stay in the bank for VON 5-6?
