The Vaults of Atal'Utek — what is in there, and where

  • Getting started
  • What it is: a 12.1 area on the Coiled Isle with its own map, and a second map underneath it, the Underbelly. It is open now — there is no season gate on it.
  • How you get in: a chain of four quests — Into the Vaults of Atal'Utek, then Vaults of Atal'Utek: One Coin Too Many and Vaults of Atal'Utek: A Toxic Tour, which you are given together, then Vaults of Atal'Utek: The Altar of Corrosion. Everything below sits behind them, so do those first. A Toxic Tour is a one-time story quest, not a daily — it asks for one Patrol, one Strike, one Incursion and one Ancient Foe, so it completes itself while you do the loop described below.
  • What you do here
  • What you actually do here — four things, and they feed each other. Temple Patrols wander the map and rotate about every ten minutes; they are the easiest thing to join and the one that is nearly always running. Temple Strikes are bigger, and they are what builds toward an incursion. Once enough Strikes are done a Temple Incursion begins, and every Incursion ends by waking an Ancient Foe — which is where the three rare elites come from, on a ten-minute clock. Coins, keys, gear and reputation all come out of that loop, so if you are wondering what to do, the answer is join whatever is running.
  • How do I actually find a Temple Strike? Open your map inside the Vaults and look for the event icons — a Strike is marked there like any world event, and it has no timer: it sits and waits until a group finishes it, so you can take your time walking over. A few players is enough; you do not need a premade, and other people are usually already on it. There are six, and each starts in a fixed spot — click one to set a waypoint: Cursed Depths (50.55, 15.70) · Overflowing Venom (47.36, 46.17) · Profane Pyres (47.67, 46.34) · Purifying Earth and Sky (47.26, 26.69) · Ruuk’Jar’s Clutch (39.32, 39.92) · The Underbelly (52.25, 36.27).
  • If the map shows nothing, run Patrols for a while. Strikes appear because Patrols are being done, so the fastest way to make one exist is to keep playing.
  • Getting around inside. The Amani Windcallers fly you between three points in the Vaults — the Amani Foothold hub, the Eastern Amani Outpost and the Northern Amani Bulwark. The flight master Eagletender Mal’Tiki stands at Amani Foothold (44.42, 62.21). You cannot fly inside the Vaults, which is exactly why they are there — the place is bigger than it looks and walking it is the slow way.
  • The repeatables — one weekly and seven group dailies. Purging the Vaults from Warleader Abdumati at the entrance is the weekly worth not missing. The seven dailies are Patrolling the Temple, Bounty of the Cursed, Relentless Strikes, Decisive Incursions, From Whence it Came, Essence of Malice and What's Out There? — take whichever your map offers today. Every one of them asks for the activities above, so they tick themselves off while you play, and a group daily just means the people already standing next to you, not a premade. And one you would never find by being here: Midnight: Vaults of Atal'Utek is a weekly meta for this place that you pick up in Silvermoon.
  • Coin and Soul
  • Corrosive Coin is the zone's currency. The game's own words: “Spirits of the Amani within the Vaults of Atal'Utek deal exclusively in this phantasmal token.” Your balance is the number above this article.
  • Corrosive Soul is not that. It is not a currency at all but an item in your bags, and it is what the Corrosive Codex asks you to offer. Guides swap the two names constantly; the game never does. If something tells you to spend Corrosive Coins at the Codex, that is the mix-up.
  • Where the coins go — two places, both at Er’inye at Er'inye (51.10, 62.76). Talking to him buys Corrode Spirit, which is what feeds the Altar tree; beside him the Skull of Er’inye is a merchant with three pages of mounts, pets, ensembles and recipes, priced from 500 to 25,000 coin. The corrode price climbs every time you buy it — seen at 1,500 and then 2,000 on one visit — so read the window rather than saving up for a number.

Altar of Corrosion: the four keys

  • The Altar of Corrosion is the node tree the last quest of the chain opens. Most of it unlocks as you spend, but four nodes sit behind a key you have to go and find — and all four work the same way: an item drops, you use it on one object somewhere in the Vaults, that gives a quest item, and Er’inye takes it from there.
  • Corroded Key → the Venom-Worn Coffer → Run of the Vaults (Glideways, or Swift Steps) · Spirit Loupe → the Feather of Tok’jara at Feather of Tok'jara (48.46, 25.80) → Spectral Winds (Spirit Walk, or Spectral Shipping) · Excising Knife → the Eye of Szarith, in a venom pool in the Underbelly → Broodmaster (+100% damage to eggs, or −75% damage from egg bursts) · Dispelling Charm → Jin’tal’s Reliquary in the Profaned Mausoleum → Spiritual Protection (ghostly allies at Curse Surges, or getting straight back up when you die outside the Vaults).
  • Showing a key to Er’inye does not unlock anything. He is blind, and he tells you what he feels — that is a hint about where the thing belongs. Where the keys drop is not settled: three careful reads of the same database gave three different answers, so we are not going to name one. Run Strikes and Incursions and they turn up.
  • Spend your first coin on the tree straight away. Its first four nodes cost nothing and unlock as you spend elsewhere, and they raise the Corrosive Coin you earn by 25, 50, 75 and finally 100 percent. The tree pays for itself, so every lap after the first one is richer — saving up is the expensive choice. And note the asymmetry that sets this zone’s pace: coin has no cap, while Corrosive Souls are rationed. Farm coin freely; do not plan an evening around souls.

The Honored Dead & the rares

  • “The Honored Dead” — twelve memorials on the Vaults map, one achievement, and the clearest thing here to just go and do. In one walking order, from the top of the map downwards:
  • To a sister 46.79, 7.51 (46.79, 7.51) · To a shield-bearer 56.49, 22.88 (56.49, 22.88) · To a father 47.22, 28.77 (47.22, 28.77) · To a stranger 42.57, 33.18 (42.57, 33.18) (under the bridge) · To a captain 52.91, 33.90 (52.91, 33.90) · To a dream 55.62, 40.60 (55.62, 40.60) · To sons 42.84, 39.93 (42.84, 39.93) · To a lover 52.21, 45.12 (52.21, 45.12) · To Comrades 38.50, 47.66 (38.50, 47.66) · To parents 55.31, 48.45 (55.31, 48.45) · To a daughter 49.50, 56.59 (49.50, 56.59) · To Failure 45.81, 61.79 (45.81, 61.79)
  • The Underbelly is the map below, entered at The Underbelly (47.30, 11.20) on the Vaults map. One rare lives down there, Szarith the Fanged at Szarith the Fanged (38.40, 17.69), and the Underbelly carries its own achievement, Soft Underbelly.
  • Three rare elites on the main map — Congealed Malice, Khu'tulak and Susarikk — make up a third, Oppose the Foes. They have no fixed spot, and that is the answer rather than a gap: one of the three wakes up the moment a Temple Incursion is completed, and you have about ten minutes to kill it. So you do not go hunting for them — you finish Incursions, and one comes to you.

Corrosive Codex — which gift do I take first?

  • Twelve gifts, and you may use one of them. Every single one costs 8 Corrosive Souls, so all twelve together cost 96. Because the price is the same for all of them, your first pick is about what you need — never about what you can afford.
  • One thing explains the whole system
  • It is a poison loop. Half the gifts get stronger against an enemy that is Poisoned, or while you yourself are poisoned.
  • That is why every good pair is one gift that poisons + one gift that pays off on poison. Once you see that, the combinations stop looking random.
  • Which one first? Pick by your problem, not off a list
  • I just want to hit harder → Ula'tek's Gift. It works on its own, with no second gift and no setup. Every guide we read names this one first.
  • Groups of enemies take too long → Plague of Corrosion or Ophidian Maw.
  • I keep dying in delves → Virulent Mucus swallows the big hits, Gorgoneion Gaze freezes everything around you the moment you drop below half health.
  • Casters keep getting their spell off → Accursed Poison. It interrupts one cast for you.
  • Watch out with Mephitic Cloud. It lets affected enemies heal whatever they are attacking. In a group that works against you.
  • What we measured ourselves, and what we did not
  • Out of the game: the price of 8, and the full text of Ula'tek's Gift. Those are ours.
  • Out of guides: the order above, and how many gifts open the second slot. The game itself only says "until your offerings are sufficient" and names no number. Six sources say 8 — including Wowhead's own spell page, which puts it in a table — and one blog says 6. So 8 is very probably right; we simply have not seen it happen ourselves. You will know the moment your second slot appears.
  • Ula'tek's Gift has already been tuned down once. A ranking from August is not automatically true today — which is exactly why the poison loop above is the part worth remembering.
