The recent releases of Patch 12.1 and Season 2 have further expanded the playable content in WoW Midnight; among the new additions, the new raids and dungeons likely offer the greatest appeal and the rarest rewards.
However, before you tackle the new raid, you will discover that its location, Vaults of Atal'Utek in Coiled Isle zone, is itself a new addition to the game. Beyond the raid entrance, this area features numerous public events that offer their own rewards.
If you aren't quite ready for Venomous Abyss Raid yet, or simply prefer to clear these smaller, scattered tasks first, this guide is here to help!

How to enter Vaults of Atal'Utek?
First, ensure you have completed the main campaign questline The Curse of Ula'tek to unlock access to Coiled Isle. Vaults of Atal'Utek is an underground sub-zone within the island, accessible via three entrances located on the western side of the isle.
Regardless of which entrance you choose, the game grants you Serpent's Path buff within the corresponding tunnel, increasing your ground mount's movement speed until you reach Vaults of Atal'Utek itself (flying mounts cannot be used during this transit).
Unlocking and completing public events
Upon entering Vaults of Atal'Utek, your first step is to locate Warleader Abdumati or Mok'sa the Stone to pick up and complete the introductory quest, Into Vaults of Atal'Utek.
While the quest ostensibly tasks you with finding three NPCs, Naz'ara the Brave, Hawkeye Socho, and Commander Gazba, it effectively serves to familiarize you with the area's flight masters and other key locations.
Completing this unlocks the next quest: Vaults of Atal'Utek: A Toxic Tour. This requires you to complete a Temple Patrol, a Temple Strike, and a Temple Incursion once each, followed by the defeat of an Ancient Foe. These activities are the public events of Vaults of Atal'Utek, collectively known as Temple Assaults.
Once that quest is finished, you can complete the weekly objective Purging the Vaults by clearing a set number of public events and smaller tasks each week to earn additional rewards.
Temple Patrol
As the simplest type of public event, there are eleven variations of Temple Patrol; three spawn every 10 minutes. They must be completed solo, though fortunately, each takes only a minute or two. Completing one grants a small amount of gold and Corrosive Coins.
Temple Strike
This event supports both group and solo play but is slightly more difficult; each Temple Strike requires you to complete two specific objectives. Rewards include a Corroded Pouch, which contains Corrosive Coins and other special items.
Temple Incursio and Ancient Foe
These two parts are linked; Ancient Foe awakens once Temple Incursio is completed. Venom-Drenched Sack obtained after finishing this public event contains a richer variety of items.
There are three rotating modes for Temple Incursio. A single challenge involves multiple objectives that must all be completed within 10 minutes, so tackling them as a group is recommended.
Correspondingly, there are three Ancient Foes, Congealed Malice, Susarikk, and Khu'tulak, that rotate weekly and must also be defeated within 10 minutes.
Altar of Corrosion Mechanics
Beyond the various missions and challenges, Vaults of Atal'Utek and Coiled Isle zones offer exclusive ability bonuses. These abilities stem from Altar of Corrosion, which functions essentially as a special passive skill tree.

How to unlock the altar?
While exploring Vaults of Atal'Utek, you may encounter an NPC named Er'inye, triggering the quest Vaults of Atal'Utek: One Coin Too Many.
After completing that, travel to Amani Foothold to meet Er'inye again. Accepting and completing the quest Vaults of Atal'Utek: Altar of Corrosion unlocks Corrode Spirit mechanic, granting access to the various abilities at altar.
How to unlock more Corrode Spirit abilities?
Remember Corrosive Coins earned from completing Vaults of Atal'Utek public events? You can exchange them with Er'inye for special Corrode Spirit points to unlock additional nodes on the passive skill tree.
Altar talent tree features 18 nodes where you can invest Corrode Spirit points. Among them are four special nodes that require you to locate specific relics and turn them in to Er'inye to activate. Activating these is mandatory to unlock the tree's core damage node, Venom Coating.
If you have no plans to unlock further Corrode Spirit abilities, or if you have accumulated surplus Corrosive Coins, you can trade with Skull of Er'inye (located next to the passive tree) for various interesting cosmetic items.
How to utilize Corrosive Codex?
Defeating Ancient Foes yields a Corrosive Soul as a reward; obtaining this triggers an introduction to a new mechanic known as Corrosive Codex.
Upon acquiring your first Corrosive Soul, WoW Midnight grants you Codex of the Soul Coilers and initiates the quest Corrosive Gifts: Corrosive Power.
Completing this quest allows you to take the codex to Altar of Corrosion, where you can learn to convert Corrode Spirit into a Corrosive Gift and unlock your first one.
The key difference between these gifts and Corrode Spirit is that gifts can be utilized throughout the entire WoW Midnight world, rather than being restricted to Vaults of Atal'Utek or Coiled Isle.
Every 8 units of Corrode Spirit can be converted into a permanent Corrosive Gift. Once you have unlocked eight distinct gifts, you gain the ability to activate two simultaneously, significantly boosting your efficiency, though this naturally requires a greater investment of spirits and coins.
Success in WoW Midnight Vaults of Atal'Utek hinges on consistently progressing through weekly public events; leveraging your unlocked buffs to tackle new raids and dungeons will greatly improve your odds of success. Get started today!
