Temple of Ahn'Qiraj

This achievement and similar will result in the revisitation of Azerothian raids! Good for those who wish to see what it was like to raid in Azeroth - not so good for those who have painful memories of 20/40 mans that they raided to death. Still, fun.

C'Thun is the last boss of AQ40: Temple of Ahn'Qiraj.

*brain melting* Periods and commas, they are your friends. But yeah, it seems that he can be done pretty easily with just a few 80s, the problem is getting past twin emps.

For players willing to complete this achievement, I suggest you to look for some info about the last 2 bosses (C'thun and the Twin Emperors) in wowwiki. This is a level 60 raid, but you can easily wipe even at level 70 if not everyone knows the fight and if you don't make a set-up in your raid for each fight.
This post is extremely outdated. As long as you can pull over 60k dps, you should be fine on twin emperors. C'thun also shouldn't be a problem.
