It feels like forever ago that Blizzard announced Malthael from Diablo III: Reaper of Souls would be making his (its?) way into the Nexus, but it was actually only like a week ago. He’s been playable in the game’s PTR ever since he was announced, but he was only recently added to Heroes of the Storm‘s official roster.
Malthael is an assassin who relies heavily on his Reaper’s Mark trait, which is applied to enemies via basic attacks and certain abilities and lasts four seconds. The mark reveals enemies for four seconds and deals 2.5% of their health as damage every second it’s active, making him killer (lol) versus high health enemies. He also looks supremely badass.

“Once the Aspect of Wisdom, Malthael abandoned heaven after the Worldstone’s destruction,” explains the description. “In secret, he had resolved to end the Eternal Conflict by becoming a Reaper of Souls and eliminating everything affected by demonic corruption, including humanity. Now he’s made his way out of the high heavens, and into the Nexus. Death approaches!”
