N Emblems of Heroism/Valor/Conquest

If you are a few emblems away from the next target, then you may consider get them soon.
After that, we will see Dungeon & Raid Emblems and highest emblems achievement is 2500 Dungeon & Raid Emblems.

Ulduar: But I'm on Your Side

Purchase Iron Boot Flask that can turn us into every one hour. It will also change sex as well as dance moves. However, don't be on their side immediately after engaging the Assembly of Iron, just in case the attempt is not successful. Wait until 10% health of 3rd boss, then it is time to on their side.
