Season 11 of Diablo 4 brought a wave of mysteries, and one of the most talked-about features has been the Purified Essences. Players have been stumbling upon these rare items and the mysterious altars scattered across Sanctuary, prompting a community-wide search to figure out their purpose. This guide goes over what Purified Essences are, how to farm them, and exactly where you can use them, including detailed altar locations.

What Are Purified Essences in Diablo 4 Season 11?

Purified Essences are rare items associated with each of the lesser evils: Asmodan, Belial, Andariel, and Duriel. These essences are distinct from the corrupted versions, which are used for boss chests and other loot. Throughout Season 11, players have gathered these purified versions without initially knowing their function, adding a layer of excitement and confusion. Eventually, it became clear that these items in Diablo 4 Season 11 are key to activating hidden altars around the world, leading to a unique boss encounter and substantial loot.

Where To Find & How To Farm Purified Essences

Each Purified Essence is tied to specific activities and bosses:

• Purified Tongue of Asmodan: This is obtained by defeating Asmodan. Running Asmodan encounters, particularly in Havizar, gives you a chance for this drop.

• Sanctified Eye of Belial: Farm this essence by venturing into the Pits and defeating Belial. The Pits are the primary location for Belial-related drops.

• Purified Horn of Duriel: This item drops from Duriel, typically found by participating in Hell Tides. Summoning and defeating Duriel during these events can yield the essence.

• Purified Heart of Andariel: This essence is earned by tackling Andariel-related activities. Many players report getting it from the Undercity, but it may drop from other Andariel encounters as well.

Purified Essences are rare drops, with players often receiving corrupted versions more frequently. The purified ones tend to drop more sporadically, so persistence is required. You might notice your inventory filling up with these items, and for a while, their use may not be clear. Collecting one of each is the first step toward unlocking their true purpose.

Where & How To Use Purified Essences (Altar Locations)

Once you have gathered one of each Purified Essence, each representing a different lesser evil in Diablo 4 Season 11, you are ready to use them at specific altars hidden throughout Sanctuary. These altars remained a mystery for much of the season, with players stumbling upon them and sharing discoveries across Reddit and Discord as the secret unraveled.

What You Need Before Visiting the Altars

• Collect one Purified Essence from each lesser evil:

• Purified Tongue of Asmodan

• Sanctified Eye of Belial

• Purified Heart of Andariel

• Purified Horn of Duriel

It’s recommended to wait until you have all four purified essences before interacting with any altar. Using them one at a time is possible, but you’ll need all four to trigger the final event, so collecting them in advance makes the process smoother.

Altar Locations for Using Purified Essences

There are four unique altars, each tied to a different lesser evil. Here’s where you can find them and how each works:

1. Altar of Lies (Belial) - Sanctified Eye of Belial

• Location:
  This altar is found in the Fractured Peaks region, close to Zenith. Players can spot it on their map after some searching or by referencing community-made guides.

• How to Use:
  When you approach the altar and interact with it, the game automatically consumes your Sanctified Eye of Belial from your inventory, provided you have it. Once activated, the altar's animation speeds up, and several eyes appear, indicating the essence has been accepted.

• Observations:
  After using the essence, nothing else happens immediately, but this is the first step in the larger process.

2. Asmodan's Altar - Purified Tongue of Asmodan

• Location:
  This altar is located in Hawezar, near Zarbinzet, not far from the renowned blacksmith. You can reach it by following the southern path out of the city.

• How to Use:
  Interact with the altar while carrying the Purified Tongue of Asmodan. The altar consumes the item and changes its animation, similar to the Belial altar.

• Observations:
  The altar’s appearance shifts, but as with others, there’s no immediate, obvious effect. This step is needed to progress toward unlocking the hidden event.

3. Altar of Anguish (Andariel) - Purified Heart of Andariel

• Location:
  Find this altar in Nantu. The most direct route is to use the portal nearby, then head into the marked area.

• How to Use:
  Approach the altar with the Purified Heart of Andariel in your inventory. Upon interacting, the altar will animate as it accepts your offering.

• Observations:
  Sometimes, when a purified part is used on an altar, a message appears: “the lesser evil is satisfied and your offering was enough.” This message seems to display randomly but confirms successful activation.

4. Duriel's Altar - Purified Horn of Duriel

• Location:
  The final altar is in Kehjistan, just south of Caldeum. Head down the path from the city exit; the altar is situated in a small area along this route.

• How to Use:
  Use the Purified Horn of Duriel here. The altar's animation changes as it accepts the offering.

• Observations:
  The process mirrors the other altars, with visual changes indicating successful use.

Activating All Altars - What Happens Next?

Once all four altars have been activated with their respective purified essences, a portal appears. This is the entrance to a special boss battle event, often described as a boss rush reminiscent of Diablo II’s Uber Tristram.

• Boss Rush Event:
  Inside the portal, you face off against the lesser evils in sequence or combination. The fight is intense, with multiple bosses attacking, and demands a solid build and preparation.

• Loot & Rewards:
  After defeating the bosses, you will be showered with loot, including a Resplendent Spark, Shield Crest of Exile, Tribute of Ascendants, and a substantial number of uniques. The sheer volume of drops can fill your inventory, so it’s wise to clear it out beforehand.
