Key takeaways

Prioritize the main event loop: Temple Strike → Temple Incursion → Ancient Foe, as it gives the best Corrosive Coin and weekly reward value.
Spend early Corrosive Coins on Altar of Corrosion progression, especially Coin-generation and movement talents, before buying cosmetics.
Complete rotating Vault achievements and weekly rewards whenever available, since Ancient Foes, Strikes and Patrol variants can delay long-term progression.

There is quite a lot going on inside the Vaults, and knowing which activities to prioritize can massively speed up your Corrosive Coin farm and Altar of Corrosion progression. Read more for achievement guides, collector’s guide, and further mechanics.

Vaults of Atal’Utek guide

There are four repeatable activities inside the Vaults of Atal’Utek: Temple Patrols, Temple Strikes, Temple Incursions and Ancient Foes. The main event loop is Temple Strike → Temple Incursion → Ancient Foe.

Temple Patrols are optional. Temple Strikes remain active while waiting for the next Incursion, which can begin roughly 15 minutes after the previous Incursion ends. Once the timer is ready, completing the active Strike triggers the Incursion, and finishing it immediately spawns the weekly Ancient Foe.

Corrosive Codex does affect Vaults of Atal’Utek activities.

Temple Patrols

Temple Patrols are small optional activities that constantly appear around the Vaults and can be completed solo. The main event rotation is focused around Temple Strikes → Temple Incursion → Ancient Foe. Temple Patrols:

Reward 20 Corrosive Coins.
3 Patrols become available every 10 minutes.
Usually involve killing enemies, collecting items or interacting with objects.
Best used as filler between larger events.
Required for several Vaults achievements.

Do not travel across the Vaults just for a single Patrol if a Temple Strike or Incursion is active.

Temple Strikes

Temple Strikes are the main repeatable events inside the Vaults. There are 6 different types of Temple Strikes: . Temple Strikes:

Reward 75 Corrosive Coins.
Can be completed solo, but groups are much faster.
Usually involve several objectives and Elite enemies.
Completing the active Strike can trigger the next Temple Incursion.

Temple Incursions

Note

An active Incursion should almost always be your highest priority.

Temple Incursions are larger group events with a 10-minute time limit. There are 3 Temple Incursions:

Summoning Ritual – Collect ritual ingredients and defeat the summoned enemy.
Cache of the Three – Collect 3 staves and return them to the cache.
Supplies Must Flow – Escort a supply wagon and clear its path.

Temple Incursions:

Reward 175 Corrosive Coins.
Require several objectives to be completed.
Much faster with a group.
Completing an Incursion immediately summons an Ancient Foe.

Ancient Foes

Note

Only one Ancient Foe is active during each weekly rotation.

Ancient Foes are the final bosses of the Vaults event cycle. There are 3 Ancient Foes: Congealed Malice, Susarikk, Khu’tulak. Ancient Foes:

Spawn immediately after a successful Temple Incursion.
Reward 200 Corrosive Coins.
Have a 10-minute time limit.
Your first weekly kill gives additional progression rewards.

Best Altar of Corrosion talents

You will eventually be able to unlock the entire Altar, so there is no single permanent build you have to follow.

However, some talents are much more useful when your goal is to efficiently farm the Vaults.

Altar Talent	Priority	Why
Venomous Hunt	Essential	Reveals venom-enhanced enemies that can give Volatile Venom and additional Corrosive Coins.
Venomwalking	High	Reduces damage from venom pools by 75%, making traversal much faster and safer.
Swift Steps	High	Adds additional Spiritwing Gusts for faster movement around the Vaults.
Spectral Shipping	High	Adds extra Windcaller destinations, including The Underbelly.
Venom Coating	High	Gives your attacks a chance to Poison enemies and enables several Corrosive Codex interactions.
Volatility Overflowing	High	Makes venom-enhanced enemies more likely to release Volatile Venom.
Slithering Secrets	High	Allows venom-enhanced enemies to drop keys for additional caches containing Coins.
Venom Infusion	High	Improves Venom Coating, increasing its proc rate and eventually allowing it to affect multiple enemies.
Corroded Grounds	Conditional	Very good if you are gathering while farming, otherwise provides little value.
Egg Specialist	Conditional	Excellent during Ruuk’jar’s Clutch but not important everywhere else.
Venomous Sanctuary	Low	Useful defensively, but activating the shrines actually costs Corrosive Coins.

The exact order depends on which part of the tree you are progressing through, but your general goal should be to unlock Coin generation, movement and damage improvements before optional utility.
