A year ago, I started the Grizzly Hills quests in the current version (retail) and reached the My Heart in Your Hands quest. After that, I abandoned this storyline, but a couple of months ago I decided to go through it again. Then it turned out that this elixir was long gone from my inventory (as it turned out, it was temporary), and it was impossible to complete the quest without it, since thanks to it you see the spirit of Drakuru. I cancelled the quest, took it again, but the elixir simply did not appear and it was impossible to get it.
Blizzard support cannot distinguish the Drakuru elixir from the Desperate mojo from the defenders, which is also needed for this quest, but it drops from mobs, and the elixir is exclusively in the story. The gamemaster did not want to figure it out, and now I can not complete the quest storyline for the achievement with the quests in Grizzly Hills.
