The mount is in Kasha's Bag, which drops from Halazzi’s prisoner. The bag is in a corner of the room, and is not immediately obvious. You have to loot the bag. I thought maybe the mount would come in the mail, or become automatically known. Not so. Loot the bag.Thinking about it now, MAYBE it's in my bags.. Geesh, hate when I think of this at work. On the otherhand, my druid may need to run this dungeon soon..
Soloing this dungeons is effortless at 100. I ran straight to each of the bosses and was able to engage them. Sure I aggro'd mobs along the way, but I could AOE them down. Now, they are all level 85, so those 15 levels meant they didn't instant die from my rain of fire. Actually had to dps them a little.
