Heroes of the Storm Cross Promotes Diablo III

Blizzard Entertainment is really taking advantage of their broad IP base. Starting now and until September 8th— all players who own Diablo III on PC or Mac will permanently receive the Diablo hero for free after logging into the game. Thats 5,500 gold or 7.49 USD for free!

Reaching level 12 in Heroes of the Storm will also reward a player with a pennant and unique portrait border for Diablo III and braving level 70 with a Seasonal Hero in Diablo III will grant the player Malthael's Phantom Mount for HotS. With the World of Warcraft and Hearthstone crossovers already in game... we can only expect Starcraft and maybe even Overwatch to come next!
