Diablo 4 Season 11 Vault Of The Crucible Guide: How To Complete First Capstone Dungeon & Unlock Rank 2?
Posted: Dec 16, 2025 Views: 50
As is well known, the returning Capstone Dungeons have been redesigned in Diablo 4 Season 11, becoming key to advancing through Season Journey.
These Capstone Dungeons are essentially special high-level dungeons, acting as gatekeepers to higher difficulty levels. You must complete these dungeons to unlock Torment Difficulty Tier.
Capstone Dungeon
Five Capstone Dungeons have been added in Season 11, each with unique mechanics and highly challenging boss battles. Completing them yields substantial rewards, such as unlocking the next Season Rank, additional Diablo 4 gold, Paragon Points, Skill Points, and better loot.

- Vault of the Crucible
- Hellish Descent
- Enclave of Darkness
- Den of the Apostate
- Breach of Sin
It's worth noting that the monsters in these dungeons are of fixed and high level, regardless of the player character's actual level, making them a challenging test of your character's build strength.
Here, we'll focus on showing you how to complete your first Capstone Dungeon: Vault of the Crucible. This dungeon is the gateway to unlocking the second tier of your Season Journey. Unlocking new Season Ranks is crucial because, unlike other seasons, in S11 you need to complete this objective to gain extra skill points. Without further ado, let's take a look at this Capstone Dungeon.
How To Enter Vault Of The Crucible?
First, you need to open Season Rank system from the menu. On the right, you'll see a prompt to complete Vault of the Crucible, your first Capstone Dungeon. Click the yellow icon, and you'll be automatically teleported to the dungeon.
Enter The Gatehall, defeat Master Executioner and his minions, then go through the portal to the first floor.
Floor 1: Savage Path
Savage Path is a simple level. You just need to find and defeat all the elite monsters marked with red skull icons, collecting the Animus Carriers from their bodies. Don't worry, the map is small, so you shouldn't have to spend much time completing the objective.
Once you've collected all the Animus Carriers, place them in Animus Urn. Then continue along the newly opened path, where you'll encounter your first boss - Demonic Automaton, a giant scorpion.
After defeating the scorpion, you can proceed to the next level; the exit is located in the northeast corner of the map.
Note that there is a red flame barrier there; you cannot pass through it unless you step on the golden circles that cool you down. This leads to the key mechanics of the second level.
Floor 2: Scorching Furnace
Step on the circles to enter the second level, where you will officially arrive at Scorching Furnace.
Here, you'll find the ground scorching, so you need to step on all the golden circles as you move forward. During this process, you also need to defeat three elite monsters called Barrier Wardens to continue.
- The first is located at the top after entering the level.
- The second is almost in the middle of the map.
- The last is located in the southeast corner of the map.
After defeating all three Barrier Wardens, you can find the exit by heading to the northeast corner of the map. These elite monsters are quite difficult, so it is recommended that you buy Diablo 4 items with better defensive affixes before starting to avoid accidental death and wasting your progress.
Floor 3: Curator's Forge
This last floor combines all the elements encountered so far, meaning you'll need to fight enemies while navigating through golden circles on the map to reach the northern part. Then, you'll need to fill a progress bar; once completed, simply keep heading north until you find the exit. You'll eventually reach the boss fight area, called Curator's Forge.
As before, you'll need to fight while stepping on golden circles to avoid being burned. You can also try standing on ice pillars to gain Ice Aegis, a 10-second buff that allows you to pass through flame barriers in the dungeon and provides damage over time reduction.
Curator boss here has a large-area attack that can deal fatal damage. However, you can dodge it by standing in the gaps between green pillars of light, or if possible, by getting behind him before he attacks to completely avoid the attack.
When Curator's health drops to about half, Demonic Automaton boss you encountered on the first floor will also appear. So you'll need to fight two bosses simultaneously. However, I recommend dealing with Demonic Automaton first, then Curator, as the latter is much more difficult and harder to defeat. Insisting on dealing with Curator first might lead to being surrounded.
Once you defeat Curator, you've completed Vault of the Crucible Capstone Dungeon. You can then unlock Rank II and continue to the next objective.
Rewards
Finally, upon completing Vault of the Crucible, in addition to accessing Season Rank 2, you'll receive some other valuable rewards to upgrade your character, including:
- 2 Skill Points
- Lesser Player Title
- Emissary Player Title
- Rank I Capstone Cache
- Archetype Cache
- 1 Smoldering Ash
This concludes the complete guide to the first Capstone Dungeon in Diablo 4 Season 11 - Vault of the Crucible. Overall, this dungeon isn't particularly difficult; as long as you master the techniques outlined in this guide, you can easily complete it and obtain better rewards in Season Journey.
