Quick Guide to Boss Materials in Diablo IV
Updated for Season 13: Season of Reckoning
Similar to my quick guide to mythic uniques (which aged like milk when they made things purple) I have memory problems when it comes to which bosses need which materials, and how many.
Sure, I could look at the items to see where they are supposed to be utilized, but this doesn't give me any sense of how many I need to summon the (ideally, tormented) boss.
What usually ends up happening is that I'll run off to the dungeon and check to see if I have enough materials to summon the boss. When I don't, I'll go check another dungeon. This cycle will continue until I get bored with not summoning bosses or an epic side quest presents itself!
This gets exacerbated when I say "nope, not enough mats" and the wife asks me how many are needed, and I've already run off without paying attention to the actual numbers. Yes, I look at to see if I can summon or not, it's extremely boolean for how casually I play.
For this quick guide, I'm going to keep this simple. I will not be delving into detail on where to farm each of the materials. Just focusing on how many of each material is required for each of the bosses in the rotation.
Diablo IV: Boss Summoning Lair Key Materials
Season 13: Season of Reckoning dropped alongside the Lord of Hatred expansion, and obliterated the old summoning system. For the best, as the boss-specific materials (Malignant Hearts, Living Steel, etc.) were quite the pain to keep track of.
The new system uses generic "Lair Keys" and the bosses are sorted into tiers: Initiate, Greater, and Exalted. Mephisto joins the party alongside Belial as the top tier bosses. For whatever reason, the Exalted ones still utilize boss materials rather than the Lair/Greater Lair keys. We'll see how long that lasts.
| Tier | Boss | Location | Lair Key | Drops |
|---|---|---|---|---|
| Initiate | Echo of Varshan | Malignant Burrow in Hawezar | 1x Lair Key | 1x Greater Lair Key |
| Initiate | Grigoire, The Galvanic Saint | Hall of the Penitent in Dry Steppes | 1x Lair Key | 1x Greater Lair Key |
| Initiate | The Beast in the Ice | Glacial Fissure in Fractured Peaks | 1x Lair Key | 1x Greater Lair Key |
| Initiate | Lord Zir | The Darkened Way in Fractured Peaks | 1x Lair Key | 1x Greater Lair Key |
| Initiate | Urivar | Fields of Judgement in Scosglen | 1x Lair Key | 1x Greater Lair Key |
| Greater | Duriel, King of Maggots | Gaping Crevasse in Kehjistan | 1x Greater Lair Key | |
| Greater | Echo of Andariel | Hanged Man's Hall in Tarsarak | 1x Greater Lair Key | |
| Greater | Harbinger of Hatred | Harbinger's Den in Nahantu | 1x Greater Lair Key | |
| Greater | Bloody Butcher | The Broiler in Kehjistan | 1x Greater Lair Key | |
| Exalted | Belial, Lord of Lies | Palace of the Deceiver in Kehjistan | 2x Betrayer's Husk | |
| Exalted | Mephisto, Lord of Hatred | The Birthplace in Skovos | 1x Crux of the False Prophet |
Happy boss bashing!
