Malthael’s Bargain Special Event
The latest Heroes of the Storm Special Event is Malthael’s Bargain, where you must play 15 games with a friend to get two cross-game promotional rewards. There is a catch: you must play those 15 games with a Diablo hero. The first reward is Leoric’s Phantom mount for your Heroes of the Storm loadout, and an epic loot box. In addition, you will get the Ghost Kerrigan wings in Diablo III (hopefully, next server maintenance).
