Guide to Diablo 4 Secret Altar Event in Season 11

12/17/2025 5:57:11 PM

In the newest season of Diablo 4, there’s a super cool secret event where you get to fight four big bad bosses all at once! This hidden challenge is inside the huge world of Sanctuary, and it’s packed with amazing Diablo 4 Season 11 items and rewards that every player wants.

How to Collect the Special Purified Items

During Season 11, you can find special items called Purified Essences. These are rare and look different from the normal corrupted items you usually get by fighting lesser evils. To get these purified items, you have to defeat certain bosses called lesser evils. Each boss drops its own purified item, but only sometimes, so it takes patience!

  • Purified Claw of Andariel – dropped by Andariel

  • Purified Eye of Belial – dropped by Belial

  • Purified Horn of Duriel – dropped by Duriel

  • Purified Tongue of Azmodan – dropped by Azmodan

These purified items shine with special colors and have unique borders, so you won’t miss them in your inventory. You can also get them from some world bosses like the Infernal Hordes.

Once you have one of these purified essences, it can be used to open the way to a secret and very tough fight.

Where to Use the Purified Items: The Four Special Altars

Scattered around the Sanctuary are four altars. Each altar matches one purified item. To start the secret event, you need to bring the correct purified item to its matching altar and activate it. When all four altars are powered up, a portal will appear that takes you to a big battle where you face all four lesser evils at the same time!

Altar NameWhere to Find ItItem Needed
Andariel's AltarNahantu, Seven Stones area (northeast of Chakir stronghold)Purified Claw of Andariel
Belial's AltarFractured Peaks, Seat of the Heavens (east of Zenith dungeon)Purified Eye of Belial
Duriel's AltarKehjistan, Caldeum (west of city gates)Purified Horn of Duriel
Azmodan's AltarHawezar, Umir Plateau (northeast, Lost City of Ureh)Purified Tongue of Azmodan

You do not have to activate all the altars in one go. You can place purified items on different days and the game will remember your progress. Once the last altar is activated, the portal will open.

The Big Fight and Awesome Prizes

When you activate all four altars, a portal shows up at the last one you worked on. Step through and get ready to battle all four lesser evils at once! This fight is very hard, but the rewards are super exciting and make it worth the challenge.

Here’s what you can get from this secret battle:

  • Resplendent Spark — a rare, shiny item to help improve your gear

  • A cool horse trophy cosmetic to show your victory

  • One unique item from each boss’s special loot list, and all are guaranteed to be super strong ancestral items

  • Seasonal consumables tied to each boss

  • Extra goodies like runes and tributes that you can use to upgrade and craft

This fight can be done alone or with friends. Strong heroes like Paladins or Sorcerers can take down the bosses faster, grabbing lots of valuable Diablo 4 Season 11 items.

Some players say that teaming up makes it easier to get a special mythic key that unlocks even more adventures in the undercity. You can also try this challenge on different difficulty levels, including the easier Torment One, so everyone can join the fun.

Helpful hints:

  • Keep killing the right bosses to get all four purified items — they don’t drop often, so be patient!

  • You can activate the altars in any order and whenever you want.

  • Be prepared: the bosses are tough and can take a lot of damage, so bring your best gear.

  • After winning, collect your loot fast because some items might disappear if left behind.

Extra Tips for Players

If you want to get stronger faster, visiting the D4 gold shop might help. Buying gold can make crafting and upgrading your gear much quicker, so you’re ready for these big fights.

Remember, this event is only available during Season 11, so don’t miss your chance to try it out and grab those awesome Diablo 4 Season 11 items.
