A new Heroes of the Storm patch that brings World of Warcraft dragon queen Alexstrasza to the fight is now live on the PTR. Alongside the new hero, the update also brings in numerous improvements to AI, a large number of bug fixes, and what appears to be a fairly major overhaul to Li Li.
Alexstrasza's basic abilities include Gift of Life, which enables her to sacrifice 15 percent of her current health to heal an ally for 150 percent of that amount; Abundance, which will heal nearby allies for 20 percent of their maximum health; and Flame Buffet, a fireball that flambés enemies for 75 damage over 5.5 seconds, or 125 bonus damage if they're already on fire. Her Lifebinder heroic ability chains her life force to an ally, giving the lower of the two a health percentage boost, while Cleansing Flame drops fireballs from the sky that restores 300 health to nearby allies, and does 150 damage to enemies.
