Remnants of a Shattered World

This isn't an item you have to loot. It is awarded in the chest received after completing the Vision of Orgrimmar.

For example, it is not an item you need to pick up in the room. Just kill Thrall and gg you'll be awarded it after evacuation.

Two tips before you do this quest (learned from experience lost 30,000 essence):

1. If you have a decent ilvl (420+), do this solo. Despite most guides saying to go with a partner, I found more mistakes were made, see below.
2. USE THE ORB PRIOR TO STARTING BOSS FIGHT. The Orb, which it does not state, CANNOT be used in combat, think of it as a OUT OF COMBAT REZ - heals everyone, rezes and resets insanity, but has to be cast PRIOR to entering combat. So clear the mobs up to the shadowy entry to Thrall and then STOP and use the Orb, then enter and pop CDs and blow up Thrall being sure to follow the basic mechanics of avoiding his wind up Stun and staying out of purple ground.

If you do the above steps this is very easy, if you do not, like me, running into thrall without using the orb, you will run out of insanity and die.

Hope it helps

After getting through the trash (as easy at it is), you're probably going to be at about 1/2 sanity when you get to Thrall. Be sure to use your Sanity Restoration Orb to top yourself off before you start the fight.

Edit: The FIRST time you go into a vision you won't have access to the orb. It will probably not go well. The next time you go in, you'll have done the Archives quest and gotten the talent to get the orb.
