Items for both games
Blizzard has explained the cross-promotion efforts for Diablo III and Heroes of the Storm, which can net you some nice little extras depending on how much you play. First off, anyone who owns Diablo III (has a license) will get Diablo in the next Heroes patch — not bad! Also, if you reach level 12 (which takes a day or two) in Heroes, you’ll net a pennant and potrait frame for Diablo III.
Finally, if you reach level 70 with a Seasonal Hero in Season 4 of Diablo III, you’ll get the Malthael’s Phantom mount. I don’t think I’m willing to max out another character in Diablo III right now, but I’m still playing Heroes on a regular basis.
