All of Blizzard’s cross-game goodies collected in one convenient place!

Blizzard has released multiple cross-game rewards (both free, and paid), and I think it's about time someone put them all together in one convenient guide! Whether you're a completion, enthusiast, or just have a lot of time and money on your hands, this list will be your go-to source for all the currently available cross-promotion goodies! There's a few of these so let's get started with the freebies right away!

Diablo III x Heroes of the Storm (Part 1)

While you can't get a free Diablo hero for Heroes of the Storm anymore, you can still get the Malthael's Phantom mount in Heroes of the Storm by reaching level 70 with a seasonal hero in Diablo III on PC and Mac. This is retroactive if you already have a level 70 hero in any season after Season 4 of Diablo III.

Diablo III x Heroes of the Storm (Part 2)

Players who get to a player level of 12 on their Heroes of the Storm account will receive a free pennant and portrait frame in Diablo III (PC and Mac players only). This is retroactive to anyone who has already hit level 12 in Heroes of the Storm so don't worry if you already passed that level during beta!

Hearthstone x Heroes of the Storm

While there are no rewards for Heroes of the Storm coming from Hearthstone, you can get a nifty card back for your Hearthstone deck by reaching level 12 in Heroes of the Storm. Sure, it's not the greatest card back in the world, but it's free and retroactive like all other cross-promotion rewards!

World of Warcraft x Heroes of the Storm

World of Warcraft players who have reached a player level of 20 in Heroes of the Storm will recieve a free Grave Golem combat pet to aid them in their heroic endeavors across Azeroth. On the other hand, if you reach level 100 in World of Warcraft with any character you will get the Ironside Dire Wolf mount for Heroes of the Storm.

Hearthstone x World of Warcraft

This one's a simple one: play 3 rounds of Hearthstone to get a free mount for World of Warcraft! The Hearthsteed Mount is not the greatest mount you can get in the game, but once again: it's free, guys!

This marks the end of the freebies, but there's still more content to go! It's time for the Digital Deluxe and Collector's Edition bonuses!

Starcraft II: Heart of the Swarm - Digital Deluxe

At this moment the only way to get the Heart of the Swarm digital deluxe is by getting the Starcraft II Anthology Digital Deluxe. This comes with a hydralisk and zergling banner sigil and the Queen of Blades's wings for Diablo III, and a baneling pet for World of Warcraft. While the rewards are nice, they're hardly worth forking out $40, so only get this if you really want it.

Starcraft II: Legacy of the Void - Digital Deluxe

This digital deluxe also comes with the Starcraft II Anthology, but it comes with significantly more than the Heart of the Swarm bundle. Cross-game rewards in this bundle include: a card back for Hearthstone, a probe and Protoss-themed armor for Diablo III, Zeratul's ship as a mount for Heroes of the Storm, and an Archon battle-pet for World of Warcraft. It's once again $40 to upgrade to Digital Deluxe, but it's well worth it if you're missing the digital deluxe bonuses for Wings of Liberty or Heart of the Swarm. It's also great if you're just pre-ordering Legacy of the Void.

World of Warcraft: Warlords of Draenor - Digital Deluxe

Personally, I've never understood why anyone would pay to play an MMO like World of Warcraft. However, if World of Warcraft is among your Battle.net collection, then I guess you might as well pick up the digital deluxe. However, the rewards for this are abysmal compared to other digital deluxe packs. In my opinion the Hearthstone card back, the Diablo III pennant, and Starcraft II portraits perfectly reflect what I think about World of Warcraft: it's a $80 rip-off.

But hey... if this tickles your fancy, go for it. Who am I to judge?

This marks the end of the cross-game rewards currently available to Battle.net users! Feel free to check back in the future for any changes if Blizzard announces new games or content!
