[WoW Classic Era] I used the Scroll of Myzrael to summon Myzrael, but failed to kill her and she despawned. I have read that in this event, you are supposed to go back to Theldurin the Lost in Badlands to get a new scroll, since they are single use. I have come back to Badlands, but I cannot get a new scroll from Theldurin; I can’t even talk to him.
Specifically, it says you need to abandon the quest and reobtain the quest.
