All New Diablo Immortal Helliquary Bosses & Inferno Difficulties

In Diablo Immortal's Splintered Souls update Blizzard isn't pulling any punches, unleashing new Helliquary bosses for players to conquer as endgame content, amongst other things such as awesome Familiar Companions and even a new zone.

In this guide, we focus on introducing Diablo Immortal players to the new Helliquary bosses, outlining their lore, and, for some, which Inferno difficulties they unlock, so let's leap in.

Diablo Immortal New Helliquary Bosses

There are a total of five new Helliquary bosses in the Diablo Immortal Splintered Souls update for players to group up and attempt to defeat. They can be encountered across three new difficulty levels in the game's biggest update ever, and are well worth slaying just for the rewards!

You'll find an image of each new Helliquary boss in Diablo Immortal following the Splintered Souls update on 14 December 2023, alongside some official lore text and new Inferno difficulty level unlocks.

Iphael, Knight of Broken Stone

A new Helliquary boss in Diablo Immortal's Splintered Soul update that does not unlock a new Inferno difficulty level. 

"A knight devoted to his Inner Light, Iphael was attacked by a strange beast in the Dreadlands. It pierced his armor and he fell deathly ill, plagued by visions of madness and voices bound in agony. His faith was not enough to save him from becoming more beast than man—now he only seeks to dominate others and sow terror as he crosses the land."

Elsauli the Shardheart

Defeating Elsauli the Shardheart grants a tonne of loot in Diablo Immortal, but does not unlock a new Inferno difficulty.

"Formerly a mage seeking to understand the nature of reality, Elsauli discovered a small splinter of the Worldstone; but in attempting to retrieve it, he pricked his finger. That was enough to end his life once; the risen Elsauli gave into the promises of clarity about the world from a chorus of voices beckoning him. He took his place of power quickly, becoming a dominant voice in the chorus of the Shardborne and spreading his madness to others."

Drepsaigh, Blightspewer

Defeat Drepsaigh on Inferno Difficulty IV to unlock Inferno Difficulty V (Paragon Levels 1200–1399).

"Drepsaigh is a pustulant, lumbering monster covered in undulating cancerous growths. This horrific facsimile of humanity was born in the Underdeeps, made by the power of creation run amok. He spews pestilence and bile and commands legions of mutated beasts."

Iscea, Twofold Rebirth

Defeating Iscea on Inferno Difficulty V unlocks Inferno Difficulty VI (Paragon Levels 1300–1399).

"The cobbler who would become the Twofold Rebirth somehow endured the piercing splinter-storms of the Dreadlands for weeks, leaving her transformation into a Shardborne unusually incomplete. The monstrous thing that now wears Iscea’s skin wields the echo of her humanity like a weapon, allowing her to control the minds of humans with a simple glance."

Peisthal, Underearth Empress

"In the dark, vermin-infested caves below the Dreadlands, the Shardborne brought a voracious hive to heel when they introduced corrupted Worldstone splinters to its queen. She is not one thing, but many, and they are all vile and all hungry. Worse yet, she is not done being changed by the power of creation. Her most diabolical and beautiful form has yet to come."
