The Diablo 3 site has been updated with a new guide for Reaper of Souls, the forthcoming expansion. In it, the team lays out the plans for both enchanting of player items and 'transmogrification', or the changing of an item's appearance. World of Warcraft players will be familiar with this feature.
Have you ever looted an item whose stats were almost perfect, but one property just wasn't quite what you had hoped for? Or perhaps you found an item you love, but are starting to outgrow its power? With Enchanting, you will be able to reroll one property on a Rare or Legendary item simply by speaking to Myriam, opening up her Enchant menu, and then paying a material cost. It's that easy!
While not all properties can be rerolled, most can, and you'll be able to reroll a single property over and over again, as many times as you like. This allows Enchanting to feel meaningful, while still allowing lots of room for you to hunt for even better base items (which, of course, you can then Enchant into even more powerful items, and so on).
