The Venomous Coiler is a terrifying, multi-headed serpent whose venomous presence and writhing form embody the deadly essence of the Vaults of Atal'Utek. Its sickly green scales, multiple heads, and the toxic miasma that surrounds it make it a favourite among collectors who appreciate mounts with a dark, monstrous aesthetic. The flavour text speaks to its lethal nature: "A native of the deadly venom pits within the Vaults of Atal'Utek, this monstrosity poisons the air it slithers past." For collectors who value prestige and the satisfaction of completing a challenging meta-achievement, this mount is a true trophy — a symbol of your mastery over the Vaults' most demanding content.
Introduced in patch 12.1.0 as part of the Midnight Season 2 update, the Venomous Coiler is the ultimate reward for completing the Assault the Vault meta-achievement. This isn't a mount you can simply farm or buy — it's a badge of honour earned by completing 10 distinct achievements tied to the Vaults of Atal'Utek's repeatable content. The journey requires you to engage with every aspect of the Vaults: patrols, strikes, incursions, Ancient Foes, and even mastering the Altar of Corrosion system. For players who enjoy a varied and comprehensive challenge, the Venomous Coiler represents one of the most prestigious rewards of Midnight Season 2.
The Venomous Coiler is awarded upon completing the Assault the Vault meta-achievement, which requires you to complete 10 sub-achievements related to content within the Vaults of Atal'Utek. This is a 100% guaranteed acquisition — there is no RNG involved, no rare spawns to camp, and no low drop rates to overcome. Simply complete all 10 achievements, and the mount is yours. Many of these achievements can be completed passively through regular gameplay in the Vaults. We recommend checking your current achievement status in your Achievements tab to track your progress.
This meta-achievement consists of 10 sub-achievements:
Below we will cover how to complete all of these achievements and earn the mount.
Before you can begin working on these achievements, you must first gain access to The Coiled Isle. The island becomes available during the main campaign questline The Curse of Ula'tek in Patch 12.1.0 during Chapter 2. The quest What Lies Beyond the Fog sends you to the island.
Once you've completed the introductory questline, you are able to fly over to the island on every character that is part of your Warband. If you haven't completed the campaign on your main character, you will need to do so before you can access the island on your alts.
As you progress through the main campaign, you will automatically unlock access to the Vaults of Atal'Utek, the subterranean heart of the island's repeatable content. The Vaults house Temple Patrols, Strikes, Incursions, and the Altar of Corrosion. No additional quests are required — simply follow the campaign until the Vaults become available, and you'll have full access to all activities needed to progress the achievement.
To complete Roll the Patrol, you'll need to complete the following patrols within the Vaults of Atal'Utek:
Temple Patrols are marked on the map with a circular star icon. Each location will have a Temple Patrol NPC to chat with, and doing so will give you a bonus objective to complete in the area. Temple Patrols rotate every 10 minutes.
To complete Submerge the Incursion, you'll need to complete the following incursions within the Vaults of Atal'Utek:
Temple Incursions are world events that temporarily replace Temple Strikes and appear on the map as a snake icon. Incursions only last for 10 minutes, so a group is highly recommended.
There will be a message at the top of your screen when a new Temple Incursion becomes available, and in order to start it you must complete the current active Temple Strike. Successfully completing each of the 3 different Temple Incursion events will award the achievement.
To complete the A Lone Wanderer achievement, you'll need to collect the large wandering Soul Globes during the Earth and Sky event within the Vaults of Atal'Utek.
During the Temple Strike: Purifying Earth and Sky, you'll use the Shrine of Sky to transform into a Spiritwing and collect the floating orbs. Large blue orbs called Wandering Soul Globes will also be drifting through the area. Simply fly into one to gain the achievement.
To complete Ritual Behavior, you'll need to deliver one of each of the following offerings to the Summoning Ritual event within the Vaults of Atal'Utek:
The Summoning Ritual event is a Temple Incursion that lasts for 10 minutes and is marked on the map with a snake icon. This particular Temple Incursion won't always be available, as they rotate between multiple.
During this world event, you'll need to gather 3 items to throw into the Ritual Cauldron. The Ritual Altar can be found just outside of the Amani Foothold within the Vaults of Atal'Utek.
Each item comes from a different location inside the Vaults: Venomous Ooze drops from Venomous Giants, Petrified Eggs are found on the ground, and Spirit Urns are also found on the ground.
Simply gather each item one by one and turn them in at the Ritual Altar to complete the achievement.

To complete Spike the Strike, you'll need to complete the following Temple Strikes within the Vaults of Atal'Utek:
Temple Strikes are world events that appear on the map as a snake head icon. Similar to other world events in Midnight, they won't move to a new location until the current strike has been completed.
To complete Oppose the Foes, you'll need to defeat the following Ancient Foes within the Vaults of Atal'Utek:
Ancient Foes are mini world bosses that spawn after a Temple Incursion has been successfully completed.
To spawn a Temple Incursion, you will need to wait for a message at the top of your screen that says "Complete the current Strike to begin an Incursion". Once you finish the active Temple Strike, a 10 minute event called a Temple Incursion will begin.
We recommend grouping with other players so you can complete the event in time and defeat the Ancient Foe.
To complete Dance While Everyone Watches, you'll need to dance while defending each of the stones in the Cache of Three event within the Vaults of Atal'Utek:
During the Temple Incursion: Cache of the Three event, there will be 3 shrines marked on the map you'll need to /dance near: the Shrine of Serpents, the Shrine of Shackles, and the Shrine of Venom. While the event is active, /dance in the circle surrounding the shrine for a few moments uninterrupted until confetti appears. We recommend using crowd control abilities or immunities to help avoid being interrupted.
To complete Soft Underbelly, you'll need to eliminate the following threats inside the Underbelly within the Vaults of Atal'Utek:
The Underbelly is located underground, at the very back of the Vaults of Atal'Utek.
3 of the threats are available during The Underbelly Temple Strike: Champion of the Scale, Priest of the First Rattle and Guardian of the Sacrifice. Once they are defeated, the threats will not respawn until Temple Strike: The Underbelly appears again in the rotation.
The other 2 threats (Szarith the Fanged and Vserix the Sneaky) are also found inside of The Underbelly area of the Vaults of Atal'Utek, but don't require The Underbelly Temple Strike to be active.
To complete Fully Corroded, you'll need to unlock every talent point at the Altar of Corrosion within the Vaults of Atal'Utek.
