Guide of Ra Den, available at Pinnacle of Storms (Throne of Thunder). Lei Shen's life changed forever when he staggered into the chamber obscura below what is now the Mogu'shan Halls. Legend has it that he found an ancient titan guarding a miraculous device known as the Nalak'sha Engine. No one knows what happened between these two beings, but Lei Shen came out of that place with enough power to forge an empire. The fate of the guardian and his current whereabouts remain a mystery
Ions: This is the "Algalon" of the area; an extra boss for more experienced raiders who have completed the main zone progression. Lei Shen is the real final boss in the area, and we wanted to make sure that was the case. Unlike what happens with Sinestra in the Bastion of Twilight, to reach Ra-den after having unlocked it, it will be necessary to go back a few steps. In the dungeon guide, the mechanics of the fight are intentionally unclear, so I won't say much more. The main objective of the dungeon guide is to provide players who are trying to learn about the encounters an in-game resource to avoid having to go out to read a guide in a web browser. In Ra-Den's case, we know that the first players to find it are probably the same ones who often write those guides online, so hopefully they'll experience a sense of discovery when they first see it.
Ra-Den skills
Heroic Only: Ra-den is only available on Heroic difficulty.
Shrouded in Mystery: There are no scholars with any recollection or record regarding the details of Ra-den's power.
Perhaps these memories have been hidden over time, or perhaps no one ever saw the Guardian of the Storms in battle and lived to tell the tale ...
