Important note: Unlike the Heart, because the Essence actually drops off a boss, you may not receive it if you already have a Mythic Darkheart Thicket lockout for the week.
~~The good news is, at present, the followup to this quest leads into Emerald Nightmare which isn't open yet, so you need not rush to get it.~~

After this, A Vainglorious Past and Tempering Darkness are completed, Kalec will give you the quest Lucid Strength.

Comment by rokeno

VERY IMPORTANT: do NOT do the mything dungeon again for this quest if you have already done in that week. You will not receive the item from OakHeart because is lootlocked. You will only receive credit for killing the Shadow.

Comment by generalhiggins

I picked up this quest and ran mythic+2 Darkheart and did not receive credit. I'm assuming this is because you cannot loot the quest item since you can't loot anything in mythic+. I also did not receive credit for killing Shade of Xavius.

Comment by ATxAlien

I got the essence and turned it in and absorbed the power, but the Archmage Kalec is just stating "incredible! But the power of one essence is simply not enough." It does not give another step, only to absorb the power. Do I need to go back to darkheart thicket?

Comment by Masserati

I have had the same issue, tried to clear after clearing mythic many weeks ago. I eventually dropped the quest and went back in to do it on heroic, and still could not loot the corruption. Any thoughts on how to actually complete this?

Hand-in is at Azurewing Repose in Azsuna.

19g 40s ! Not a grand reward, what is the purpose of this quest in the long run? Quest descriptors could be more enlightening about progress.

If this quest truly is just for the gold, I would have the quest admit this.

Introduction
This quest is part of a comment-size guide for "Balance of Power." questline. Quests are pretty much self-explanatory and all it takes is some time and good will to complete them. Completing this questline rewards Artifact Appearance (Appearance 3, Tint 1).

Part 1
Image of Kalec appears in your Order Hall and gives you the following quest:
The Power Within (Meet Archmage Kalec at Azurewing Repose in Azsuna.)
Reasons behind appearance of Archmage Kalec in your Class Order Hall are not yet completely understood but most people noticed him few days after they completed their Class Campaign.

Part 2
From there you take a next quest from Senegos:
The Heart of Zin-Azshari (Retrieve the Heart of Zin-Azshari and defeat the Wrath of Azshara in the Eye of Azshara on Mythic difficulty.)

Part 3
After completing the previous quests you receive a few new quests (exactly 3: two from Senegos and one from Archmage Kalec).
Senegos:
A Vainglorious Past (Obtain a Vainglorious Draught from Veridis Fallon.)
- You can purchase Vainglorious Draught from Veridis Fallon in Crumbled Palace in Azsuna for 150g (Requirement: Court of Farondis - Honored).

Fallen Power (Recover a Corrupted Essence from Oakheart and defeat the Shade of Xavius in Darkheart Thicket on Mythic difficulty.)

Archmage Kalec:
Tempering Darkness (Obtain 30 Blood of Sargeras.)
Should not be a problem since by the time you get that quest and if you did not spend any Blood of Sargeras you should have some stacked up simply by completing Dungeons and World Quests.

Part 4
Archmage Kalec:
Lucid Strength (Absorb the power from the Corrupted Essence using the Heart of Zin-Azshari.)
Right next to you.

Part 5
Senegos:
The Wisdom of Patience (Await the opening of The Emerald Nightmare, then report back to Senegos in Azsuna.)

Part 6
Archmage Kalec:
In Nightmares (Obtain a Deathglare Iris and the Horn of the Nightmare Lord from The Emerald Nightmare.) NOTE: NOT doable with LFR. It has to be Normal difficulty or higher. In order to complete this quest you need to kill 2 bosses: Il'gynoth and Xavius and loot mentioned quest items.

Senegos:
Essence of Power (Collect 30 Corrupted Essence from The Emerald Nightmare.) This quest gave me a weird WoD and Khadgar flashback. NOT doable with LFR. Only Normal or higher difficulty. Essences ~~do not~~ have a 100% drop rate and bosses can drop 1-2 3 Corrupted Essences at the time.

Part 7
Senegos:
Essential Consumption (Absorb the combined power of the Corrupted Essences using the Heart of Zin-Azshari.)
Right next to you.

Part 8
Archmage Kalec:
Repaid Debt (Meet Archmage Kalec in the Shal'Aran in Suramar.)

Part 9
Thalrenus Rivertree:
Lost Knowledge (Obtain the Scroll of Elun'dris from First Arcanist Thalyssra.)
- Costs 120g. Requirement: The Nightfallen - Revered).

Part 10
Thalrenus Rivertree:
Borrowing Without Asking (Recover a Containment Crystal from the Vault of the Wardens on Mythic difficulty.)

Syrana Starweaver:
Rite of the Captain (Take Advisor Vandros' Eon Winder from The Arcway on Mythic difficulty.)

Lothrius Mooncaller:
Literary Perfection (Find Lothrius' first edition copy of "Wards, Sigils, and the Nightborne Way" in the Court of Stars on Mythic difficulty.)

Part 11
Syrana Starweaver:
Twisted Power (Use a Greater Portal Stone to summon Vizuul the Twisted at the Altar of End Times in Faronaar and collect his runebindings.)

Part 12
Syrana Starweaver:
A True Test (Absorb the power from the Twisted Runebindings using the Heart of Zin-Azshari.)
Right next to you.

Part 13
Archmage Kalec:
Seeking the Valkyra (Seek out Ashildir at the Vault of Eyir in Stormheim.)

Part 14
Ashildir:
The Mark (Prove your worth to the Valarjar, then receive the Mark of the Valkyra from Eyir.)

Part 15
Ashildir:
Retrieving the Svalnguard (Retrieve the Svalnguard and defeat Helya in the Maw of Souls on Mythic difficulty.)

Part 16
Ashildir:
A Feast Fit for Odyn (Acquire flank meat from Thunderhoof in Stormheim, Spinesever's spine in Highmountain, and a steak from Leytusk in Azsuna.)

Presentation is Key (Retrieve 4 Adamantium Casing Scraps and defeat Dargrul the Underking in Neltharion's Lair on Mythic difficulty.)

Part 17
Ashildir:
Odyn's Blessing (Obtain Odyn's blessing in the Halls of Valor on ~~Heroic or~~ Mythic difficulty.)
- Use Grand Feast of Valhallas when you enter the dungeon - at the start. You can enter the dungeon alone, put the feast down, get out and then get a group to defeat Odyn and get his blessing. After you defeat him wait for him to finish his speech (RP) and then you can collect his blessing on the loot chest.

Part 18
Archmage Kalec:
Planning the Assault (Await the opening of the Nighthold, then meet Archmage Kalec in Shal'Aran.)

Part 19
Archmage Kalec:
Into the Nighthold (Collect 20 Nightshards from the Nighthold on Normal difficulty or higher.)
- Try and complete this quest without killing Gul'dan because if you kill him before acquiring The Nighthold: Darkness Calls quest in Part 20 he won't drop quest item for you this week and you'll need to wait for a next reset to complete The Nighthold: Darkness Calls quest in Part 20.

Thalrenus Rivertree:
The Nighthold: Delusions of Grandeur (Collect the core of Trilliax and Grand Magistrix Elisande's Millennia Tome in the Nighthold on Normal difficulty or higher.)

Part 20
Archmage Kalec:
The Nighthold: Darkness Calls (Bring one Gul'dan's eyes to Archmage Kalec on Normal difficulty or higher.)

Part 21
Archmage Kalec:
Balance of Power (Absorb the combined power of the Nightshards and the Eye of Gul'dan using the Heart of Zin-Azshari at the Lunar Crucible.)

Congratulations on completing this questline and acquiring new Artifact Appearance. Enjoy!
Foxies, out.

Comment by hannibalektr

Did this on Mythic+ (unknowingly, thought it was mythic. But you would think Mythic and above would make this quest item obtainable right? NO! One has to do this quest exactly on mythic or have to wait until reset to get it.

Not being able to loot this item on Mythic+ is completely and totally ludicrous. Blizzard needs to fix this lame bug. If not people should be made whole when they submit a ticket.

Here is the response I got when I put in a ticket.
===============
Hey there,

Cyaniculex here, at your service! I'll be more than happy to check on your credit for Fallen Power. ^.^ Things can get a bit tricky when it comes to credit for certain quests as there are sometimes a few parameters that get missed - I hate it when I don't receive certain credit needed so I understand any concerns you have!

For this one in particular, you'll only be able to loot the quest item when you run Darkheart Thicket in Mythic. As I'm sure you're already aware, you ran twice: one in Mythic+ and the other in Heroic, which means won't be able to loot the item. Quest criteria, in this nature, is specific for which difficult to earn it in so you'll need to run the dungeon in standard Mythic so you will be able to get that item.

I realize this wasn't the resolution you were seeking but I was happy to clear things up for you. Thank you for your time and take care, my friend!

PS. If you wanted to send some ideas on changing this (as you wouldn't be the only one!), be sure to send it through the Suggestion feature from the in-game menu!

IF YOU HAVE ALREADY CLEARED DARKHEART THICKET & HAVE LOOTED OAKHEART ON MYTHIC FOR THE WEEK, YOU WILL NOT BE ABLE TO LOOT THIS ITEM AS IT DROPS DIRECTLY FROM THE BOSS.

After making a ticket to Blizzard asking about how this could be solved, this was their exact response:

Many thanks for the thorough description of the issue, this was super useful. Having looked through your case and as you have correctly identified, if you have already looted Oakheart this week prior to picking up Darkheart Thicket: Fallen Power, you will be unable to loot another Corrupted Essence. Please kindly note that Customer Support is unable to reset these types of instances, and on this occasion you will need to wait until the weekly reset to get the item again. This will be a limitation that cannot be bypassed, and full details pertaining to this can be found here:
https://support.blizzard.com/article/000053782

Although we haven't been able to provide you with the item or reset the instance in question, what we would suggest is that you provide your feedback on the community forums to the development team about this in game functionality. You can also provide your feedback in game by using the 'Submit Feedback' option. It is invaluable to hear your personal feedback and suggestions on these elements of the game, as it's player's like yourself who make us wish to continue on this journey and improve on our services. The direct link for the community forums, and the steps with which to submit your suggestions in game can be found in the following article:

Darkheart Thicket: Fallen Power

Recover a Corrupted Essence from Oakheart and defeat the Shade of Xavius in Darkheart Thicket on Mythic difficulty.

	Corrupted Essence (1)
	Defeat the Shade of Xavius (1)
	Suggested players: 5 (1)

Description

Once we have the proper implements we can use the Heart to infuse great power into your artifact. We need only a source.

Deep within the Darkheart Thicket lies the ancient Oakheart, once a great and mighty protector of Shaladrassil. He has regrettably fallen to the nightmare like so many of his kin.

As the darkness within him has taken root, an essence of the corruption has manifested. I ask that you recover the essence so that we may draw from its power, and put noble Oakheart to rest.
