It is through the archangel Auriel that the power of hope flows into the fabric of creation. Her eternal light illuminates even the darkest souls. Seeking harmony in all things, she is a mediator, a counselor, and when the need arises, a fearless warrior.
Demonic - $9.99 An angel can never truly become a demon. But once the Lord of Hatred corrupted Auriel's spirit, and bound it within a mistress of the Burning Hells, most mortals would struggle to tell the difference.
Master Hero level 10, 10,000 gold It is said that the power of the Nexus amplifies what lies within a warrior's heart. While Auriel's countenance has changed, the light of hope within her is more resplendent than ever.
Auriel shines when she has an ally that can consistently deal damage, steadily fueling her healing power. The consistent and predictable nature of Lunara’s damage also makes it a lot easier to use Ray of Hope’s healing efficiently, rarely wasting energy.
Two Heroes, each Bestowing Hope to Auriel? Who could have imagined that a two-headed ogre would offer so much hope (and power) to a team. Both Crystal Aegis and Resurrect also work great with Cho'gall, allowing you to protect or bring back two allies at the price of one cooldown.
Gul'dan turns Health into damage, and Auriel turns damage into Health. Together, they’re an engine of war. The sheer amount of area of effect and damage over time effects that Gul’dan provides really give Auriel a lot of energy to work with. And as long as she keeps healing Gul’dan, she won’t have to worry about her ally running out of Mana.
Auriel wants time for her allies to generate energy for her healing, but Diablo likes to press the issue. If Diablo chooses to concentrate his disabling effects on the character that generates the best energy for Auriel, he effectively cripples Auriel’s healing capabilities.
Zeratul’s ability to create havoc in the backline forces Auriel into really difficult situations. Zeratul is good at picking off the fragile Auriel, or her Bestow Hope target, without opening himself up to damage that would fuel Auriel’s healing. As an answer to this, Auriel might want her team whole team to group up together - but this can set them up for some nasty Void Prison setups.
While Auriel does have the potential to output infinite healing, it has the requirement of her team dealing damage to enemies. An enemy Chromie is able to dish out damage from often unreachable distances, making it possible for Auriel’s team to be whittled down without any effective reaction.
Auriel appeared in a trailer for the Eternal Conflict, but was not implemented through the expansion. However, the developers did not rule out future inclusion. She was confirmed as a playable hero in July, 2016.
