Escaping the Tomb

For those of you who don't care how many people "Soloed him as ___!, yay!" The entrance to the tunnel you find Akuno in is at coords 31.2, 52.6, the Shadow Tomb. As soon as you exit the hallway to the main room he is to the left.

I was able to solo this as a 64 mutilate rogue - incredibly challenging. You can't let him tank one as he dies within ~15 seconds of doing so, so tank and kill both as best you're able. If you clear from him to outside and run back, you can just get him to skip the first spawn.

Mobs you need to clear:
2 - Interrogator next to him and the mob closest to the Interrogator (pull it carefully so you don't get its neighbour)
2 - the mobs in the next (second) room (one patrolling, one next to the doorway)
1 - the mob in the third room
2 - outside, the mobs on either side of the entrance

This is as far as I could clear and still have time to get back to him and get him to walk and not snag the newly-spawned. Then, walking with him, you fight:

0-2 mobs in the first room, depending on whether you get back fast enough
2-4 mobs in the third room, depending on whether he aggroes the ones on the sides (two spawn here)
2-5 outside - two more spawn here and there are 3 patrollers in the area as well. How many you fight depends on their pathing.

Good luck! This is extremely gratifying to solo, especially if you overcome unexpected adds.

My best guess would be that Mekeda's Gift and Unearthed Orb were different before they changed the spellpower mechanic to replace +spell damage and +healing, with one item being of each type, and it was only after the mechanic change that the items became identical.
