The latest season of Diablo 4 introduces a slew of new Uber Endgame Bosses. To encounter these demonic bosses in Diablo 4, you must play on specific World Tiers and complete in-depth summon rituals. This primer goes over how to summon all the Uber Endgame Bosses and what loot you can get from these terrifying creatures in the iconic action role-playing game from Blizzard Entertainment.

How to summon Grigoire, The Galvanic Saint

You can encounter Grigoire, The Galvanic Saint, in World Tier III and IV, but first, you must collect an adequate amount of Living Steel from the Tortured Offering in Helltide. Grigoire, The Galvanic Saint drops exclusive Uniques, plus the Demonbinder Mount Armor Cosmetic.

How to summon Echo of Varshan

Echo of Varshan appears in World Tier III and IV. To summon this Uber Endgame Boss, you must defeat Grotesque Debtors during Whispers of the Dead and gather parts of Varshan's body. If you have the Tree of Whisperers collections, which you get by turning in Grim Favors, you'll always get a part of Varshan's body.

With enough parts of Varshan's body, you can summon Varshan. If you're playing on World Tier IV, you will need a Malignant Heart, too. Echo of Varshan drops exclusive Uniques, and you can also get the Flesh-Weld Rod Trophy.

How to summon The Beast in the Ice

Only available on World Tier IV, you can summon The Beast in the Ice by gathering Distilled Fear while completing Tier 30 or higher Nightmare Dungeons. Once you get enough Distilled Fear, visit the Occultist and craft the Glacial Fissure Nightmare Sigil. Finally, activate the Glacial Fissure Nightmare Sigil to summon The Beast in the Ice.

How to summon the Dark Master

Defeat any World Boss or complete a Legion Event on World Tier IV to get Exquisite Blood. Scavenge up enough Exquisite Blood, and you can summon the Dark Master. The Dark Master drops the sleek Diadem of the Ancient Helm Cosmetic and several exclusive Uniques.

How to summon the Echo of Duriel 

The most tedious of the Uber Endgame Bosses to summon, you can call for the Lord of Pain, Durial, after defeating Grigoire, The Galvanic Saint and Varshan in World Tier IV and collecting enough Mucus-Slick Eggs and Shards of Agony.

The Echo of Duriel is the only Endgame Boss from Season 2: Season of Blood that can drop Uber Uniques. The Echo of Duriel also has a chance to drop the Brimstone Mount.

How to summon the Echo of Lilith Endgame Boss

Before you can even think about fighting the Echo of Lilith, you must achieve level 90 and reach World Tier IV. After that, you will get a quest titled Capstone Dungeon: Echo of Hatred. From here, visit the chapel in Nevesk where the Diablo 4 Campaign begins and interact with the blood petals on the floor to enter the Echo of Hatred Instance and confront the Echo of Lilith.

If you can manage to defeat the Echo of Lilith, you will get the End of the First Mother and Silence is Hellish achievements, the Lilith's Doom title, the Reins of the Bloody Liquid Steed, and an assortment of Legendaries and Uniques.

That's all the Uber Endgame Bosses that exist in Diablo 4. You must meet the summoning conditions of an Endgame Boss each time you want to battle it, so stash extra summoning materials if you plan to go back for additional attempts.

Uber Endgame Bosses are designed to pose a challenge to high-level players, giving them something to strive for and somewhere to farm Diablo 4's most sought-after loot. Uber Endgame Bosses won't be easy, but the potential rewards are worth the effort!
