Chapter IV: Darkness Incarnate

(To Warlords of Draenor Legendary Ring Guide)

The legendary questline will require you to complete the Naval Missions in your Shipyard. You must upgrade your Shipyard to Level 2 in Command of the Seas Upgrading it in Upgrading The Fleet requires 15 Naval Missions, 1000 Apexis Crystal, and 1000 gold.

At this point, you will complete several missions until you get the [item=128693] for Master vs. Commander. These missions are hidden behind Blockade missions, meaning you will need to complete Blockade ones before accessing the legendary ones in different parts of the ocean.

[mission=633]
[mission=634]
[mission=750]
[mission=751]
[mission=752]

Another quest, We Don't Need No Library Card, sends you into [zone=7545] to retrieve 33 [item=127115]

Reward:
[item=124634]
[item=124635]
[item=124637]
[item=124638]
[item=124636]

I've made a video showing the full version of Khadgar's legendary quest line given during Warlords of Draenor. It contains both sides so Alliance and Horde, hope you'll enjoy!

Gul'dan and his shadow council were released to disconnect the dark portal, but by doing so we created a big problem. Gul'dan was willing to sell his own people to the legion and he will stop at nothing to gain more power. Khadgar recruits heroes of both the Alliance and the Horde to try and stop this evil warlock. His attempt nearly cost him his life to the assassin Garona Halforcen, but thankfully we were able to save him and even capture the half orc. After liberating her mind, we find out that the Iron Horde isn't happy with their current warchief and Gul'dan makes full use of this. It's become even more difficult to stop the evil warlock and his demonic masters...

why is this still under quests tab? its no longer possible to obtain?
