Heads up! Players who pick up a copy of Diablo III: Reaper of Souls™ will soon discover bonus loot in the form of an Expert Card Pack (or Packs!) for Hearthstone™: Heroes of Warcraft™.

Depending on the version of Reaper of Souls you have pre-purchased (or purchase in the future) you can expect the following:

Reaper of Souls: Digital Standard Edition – One (1) Hearthstone Expert Card Pack, delivered to your Battle.net account starting March 20.

– One (1) Hearthstone Expert Card Pack, delivered to your Battle.net account starting March 20. Reaper of Souls: Retail Standard Edition – One (1) Free Hearthstone Expert Card Pack, available in your Reaper of Souls box as a redeemable code.

– Three (3) Hearthstone Expert Card Packs, delivered to your Battle.net account starting March 20. Reaper of Souls: Retail Collector's Edition – Three (3) Hearthstone Expert Card Packs, available in your Collector’s Edition box as three separate redeemable codes.

Note: These Expert Card Packs require a Battle.net account to be redeemed, and a maximum of five bonus Expert Card Packs can be redeemed on a single Battle.net account. If you aren't already playing Hearthstone when the bonus Expert Card Pack keys are granted to your Battle.net account, don’t worry—they’ll be waiting for you in-game as soon as you download Hearthstone for FREE and get through the introductory missions.

So have fun in Reaper of Souls, proudly defend the mortal realms, and—when you're ready for your hero's respite—enjoy some free cards courtesy of Hearthstone: Heroes of Warcraft.
