Summoning Bosses in Diablo IV (Updated for Season 8)
Like my memory when I try to recall which bosses need what materials, this stuff gets fuzzy fast.
This is a companion piece to my quick guide to mythic unique equipment – which aged like milk once they turned everything purple. Same energy here: simple, to the point, and meant to help you summon bosses without second-guessing yourself.
I’m not diving into farming routes or spawn logic. Just a clear breakdown of how many of each material you’ll need to summon each endgame boss in Diablo IV, updated as of Season 8: Belial’s Return.
I play casually, forget numbers constantly, and get called out by my wife when I say “not enough mats” without knowing what “enough” actually means – so this is my cheat sheet (and now yours too). Admittedly, I’ve been so busy I haven’t even started Season 8 yet, but hey – research is half the battle, right?
Diablo IV: Boss Summoning Materials
A few things have changed since the early seasons—Stygian Stones are gone, and the material costs to summon bosses have been reduced. Bosses begin appearing on Torment I difficulty and beyond.
No changes were made in Season 7 (Season of the Witch), but with Season 8 now live, some new bosses and materials have been introduced.
| Boss | Location | Summoning Materials |
|---|---|---|
| Echo of Varshan | Malignant Burrow in Hawezar | 12x Malignant Heart |
| Grigoire, The Galvanic Saint | Hall of the Penitent in Dry Steppes | 12x Living Steel |
| The Beast in the Ice | Glacial Fissure in Fractured Peaks | 12x Distilled Fear |
| Lord Zir | The Darkened Way in Fractured Peaks | 12x Exquisite Blood |
| Urivar | Fields of Judgement in Scosglen | 12x Judicator’s Mask |
| Duriel, King of Maggots | Gaping Crevasse in Kehjistan | 3x Shards of Agony |
| Echo of Andariel | Hanged Man’s Hall in Tarsarak | 3x Pincushioned Doll |
| Harbinger of Hatred | Harbinger’s Den in Nahantu | 3x Hatred Hearts |
| Belial, Lord of Lies | Palace of the Deceiver in Kehjistan | 2x Betrayer’s Husk |
Happy boss bashing!
