Iben Fahd's Sanctum

The Sanctum of Iben Fahd

Iben Fahd's Sanctum (a.k.a. the Sanctum of Iben Fahd) is a zone in Diablo Immortal.


The Sanctum was created by the original Horadrim. During the Hunt for the Three, the leaders of the Horadrim gathered her and imbued their essence into vessels, storing their memories and power for future Horadrim. These became manifest in 'living memories.' A portal device (or something similar) was built under the land where Westmarch would be constructed hundreds of years later, which led to the sanctum. Inside the sanctum, the Horadrim trained in the Aspirants' Grounds.

In 1270, the Memory of Iben Fahd guided a hero to the Sanctum, deeming them fit to carry the legacy of the Horadrim.[1]


The Sanctum appears in Diablo Immortal, and is unlocked during the "Legacy of the Horadrim" quest. It is classified as a Westmarch zone, but appears to be far away from Westmarch itself. It is here that players use the Legacy of the Horadrim system.


The monsters appear outside the sanctum proper, inside the Aspirants' Grounds.



Chests can be found after going through the dungeon section. They must be opened using Aspirant's Keys. There are 5 chests per room and 4 rooms total, with some mobs spawning in between. The first chest can be opened for free, and each successive chest requires more keys to open. After opening all 20 chests, a secret chest shows up in the middle.

In the below table, the free chest's stones are not counted towards the cumulative rewards since the chest doesn't require any keys to open, whereas the final chest can be opened for free, but only after opening all 20 chests, so its reward is added to the 20th chest's reward.

Since the ratio between stones and keys goes down and down, there is no point in saving keys for a single big run.
