take your original legendary, enchant your propriety, equip it and leave game, start new game in another difficulty and in your invertory there will be your original leg, and your equipped enchanted one.
yeah, keep in mind these are legendary items before ptr, they were copied not dropped in ptr, don't have one yet but if i get one i will try to dupe it, i don't want my account banned, so how can i report this please?
