What you need to do if you want to get Mercy's wings in Diablo 3.
Here's how you can get Mercy's wings from Overwatch in Diablo 3
As with many Blizzard games, the studio is doing some cross-game promotions that net you cosmetic bonuses in Diablo 3, StarCraft 2 and Heroes of the Storm, when you buy Overwatch.
If you've already pre-ordered the Origins Edition through Battle.net directly, you should simply find the Wings in your collection stash.
If you're going for a physical version, you'll find an included code that you can later redeem on Battle.net
This is valid for owners of Diablo 3 and Diablo 3: Reaper of Souls.
-On PS4 and Xbox One
You don't actually need to own Overwatch to get Mercy's Wings on PlayStation 4 or Xbox One. Blizzard has made the item available to all owners of Diablo 3: Ultimate Evil Edition for free.
All you need to do is make sure your Xbox Live or PSN account is linked to your Battle.net account.
You'll find the item in your inventory, under the 'Bag' category.
