Registering Reaper of Souls before March 31st nets you two loot items

Diablo III: Reaper of Souls is about a month away from being release and today, Blizzard has unveiled what you can get if you register the key to the expansion pack before the end of March.

First up will be the Wings of Valor for your characters in Diablo III. They are fiery wings that sprout from the back of your character. Similar to the angelic wings that were available for those that pre-ordered Diablo III, the Wings of Valor look more like fire and will give your character an angel like appearance.

If you play Heroes of the Storm, then you'll get Valla the Demon Hunter to use in the game. There's still no release date, but once the game's ready, you'll have in your collection. 

To get both of these items, register your Reaper of Souls key before March 31 and they will automatically be added to your account.
