There's a new legendary quest series in Mists of Pandaria and anyone that's 90 can begin working on it. Multiple people in your raid can work on it at the same time, and it can even be completed in LFR. We'll show you what you need to get started this week.
A few things set this apart from past legendaries:
All players in a raid can work on the legendary questline at the same time.
Legendaries are for everyone. Players complete quests for legendary gems, which are then socketed into Sha-Touched weapons from raids. There are nine weapons classified as Sha-Touched, covering all possible specs.
With this system, guild are only limited by the number of Sha-Touched weapons they see each week.
Legendary gems can be placed into weapons from LFR. Quest items can also be looted in LFR.
This legendary series will span the expansion, with more elaborate rewards each tier.
The reward for this first tier is an epic weapon with a legendary gem, not an actual legendary weapon.
