Complete the main storyline quests involving Drakuru listed below. To finish this achievement you need to complete 2 parts.

Cleansing Drak'Tharon

This is the last quest of an 8 level chain which starts at Drakuru - located at (16,47) on the west side of Grizzly Hills. Below are the quests you will need to do first:

1. Truce? - Just right click on the dagger stuck in the tree stump next to his cage. Easy enough!


2. Vial of Visions - Now Drakuru wants you to bring him some items. The Imbued Vial can be purchased from any Trade Goods vendor. Haze Leaf is located around 15,44 and Waterweed Frond is located at 15,40.


3. Subject to Interpretation - Just kill the trolls nearby and collect 5 Frozen Mojos. Then use Drakuru's Elixir at the brazier located at 13,60.


4. Sacrifices Must be Made - First you need to kill Warlord Zimbo for his mojo. He's located at 14,37 - the biggest hut in Zeb'Halak. Next, grab the Eye of the Prophets. The location is 17,36 on top of the temple. After this you can use the mojo to speak with Drakuru again. The brazier is located on top of the same building as the Eye.


5. Heart of the Ancients - The Heart of the Ancients is located at 36,32 at the Blue Sky Logging Grounds. It will be in the very top of the building.


6. My Heart is in Your Hands - You now need to bring Drakuru the Heart at Drak'atal Passage (46,29). First, you'll need to collect 5 Desperate Mojos from the nearby Drakkari Defenders. The actual Brazier is located at 44,28.


7. Voices From the Dust - The Drakkari Tablets are located underground around 69,18. This is also where Harrison Jones is! You'll need to kill the Oracles and Protectors above the passage to obtain 5 Sacred Mojos in order to summon Drakuru. His pedestal is at 71,26.

Completing all of the above will open up Cleansing Drak'tharon. You'll need to go into Drak'tharon Keep for this one. The mojo drops off mobs inside and everyone can loot them, which is nice. The Brazier is located behind the last boss, The Prophet Tharon'ja.

Betrayal

This is the last quest of an 9 level chain that leads to Betrayal. The following are the ones you need to do first:

1. An Invitation, of Sorts... - This is the item that begins the whole chain. The Unliving Choker drops in Zul'drak off Withered Trolls, located around (20,71).


2. Near Miss - Hand the choker over to the Blood Elf female, Bloodrose Datura. She's to the left of the quest giver.


3. You Can Run, But You Can't Hide - Collect 5 Putrid Abomination Guts from Putrid Abominations (around 19,74) and 5 Gooey Ghoul Drool (around 21,75). The drools are lootable sludge looking mobs on the floor.


4. Dressing Down - Use the provided Ensorcelled Choker to buy Bitter Plasma from Gristlegut at 19,75. He'll also have a side quest Feedin' Da Goolz.


5. Infiltrating Voltarus - Use the Ensorcelled Choker to teleport inside Voltarus. Just walk up to the blue circle in the center of the Reliquary of Pain (28,45). Drakuru will give you the quest Dark Horizon. He's at 29,48 on a platform. He does not have a yellow ? mark, but when you talk to him he will send you out on a bat to tour Zul'Drak. When you've completed his task, teleport back down to the Reliquary of Pain and use Stefan's Horn to turn in the quest.


6. So Far, So Bad - Once again he sends you to Drakuru to complete a task as well as one of his own. First, take the provided Diluting Additive and throw it into 5 Scourge Cauldrons. They are located around the perimeter of the Reliquary of Pain. After this head up to Drakuru. You'll of course need to be disguised to see him again. It Rolls Downhill is his task. All you need to do is use the given Scepter of Suggestion on a Blight Geist to take control of one. The Geists are all around the Reliquary of Pain and taking control of one will give you a pet bar. You'll only have one action and each Geist will only harvest one crystal. Don't forget to use Stefan's Horn to turn in the quest when you are done.


7. Hazardous Materials - Stefan wants you to get some of those crystals that have been harvested as well as complete another Drakuru task. You'll need your disguise as these are located up near Drakuru. These harvested crystals are actually inside crates that will sparkle all along the ring. Be aware that picking up the crystals will most likely make your disguise fail, so make sure you are in a safe spot before you pick it up! Drakuru's task this time is Zero Tolerance which involves you using the given Scepter of Empowerment to enslave a Servent of Drakuru and kill Darmuk. There are plenty of servents South of Voltarus and Darmuk is located at 29,51 on a platform. Your servent will have 3 abilities that you will need to use everytime they are available to ensure success. Don't forget to use your horn to call down Stefan after you've turned in Drakuru's task.


8. Sabotage - You are now tasked with destroying 5 Scourgewagons, completing another Drakuru task and learning his secret. Use the given Explosive Charges on the Scourgewagons located around 30,45. These are not the same as the cauldrons from the earlier quest! Drakuru's task is Fuel for the Fire. Use the given Scepter of Command to take control of a Bloated Abomination, kill 60 Drakkari Skullcrushers, and lure out 3 Drakkari Chieftains. Abominations are around 33,42 (Northeast of Voltarus) and you must be in disguise to charm one of them! The trick here is to run your Abomination into as many trolls as you can and then use your Exploding ability to kill them. There is also a Flatulate ability that will knock down enemies, so use this if you are getting a little overrun. The kills will only count when you use the explode ability so don't bother using much melee on these guys. Luring the Drakkari Cheiftains is random and you don't need to do anything in particular to get them to come up. After you turn in this quest, you will receive Disclosure. The place to teleport is the platform directly above the one you came up in. The circle in the center is green. Once in the upper chamber, click on the coffin to summon Malmortis, who will give you a tour of the area. Make sure you do not summon any companions while he is out as it will make him disappear! When you are finished with the tour, you can go to the middle and teleport back to Drakuru. Once you've handed in the quest, you will get credit for finding out his secret. Now you can go back to the Reliquary of Pain and summon Stefan to turn in.


Completing the above will open up Betrayal! Make sure you use your Sceptor to Mind Control a nearby troll, or you'll have a very difficult time completing this. He hits VERY hard! Your disguise should fail before you use the sceptor and if for some reason it doesn't make sure you remove it. You won't be able to attack Drakuru with it on. If you get hurt have your mind controlled target heal you and use his stun ability whenever it is up. Watch out for the poison looking spots on the ground. If someone else has already started the quest when you arrive, mind control a troll and help them out! The quest item is a lootable item on the ground, so no need to be selfish! When you loot the skull, there will also be an item that teleports you back down to the bottom. Use your horn to turn in the quest to Stefan and get your lovely blue necklace!
