Igneous Cores are a new type of Seasonal material required to enter the Vault of the Loom endgame dungeon in Season 3 of Diablo 4 (D4). Read on to learn how to farm and use Igneous Cores to challenge the Echo of Malphas endgame boss.

List of Contents

How to Farm Igneous Cores

Defeat Heralds of Malphas in Arcane Tremors at WT4

D4 Season 3 - Herald of Malphas Igneous Core Drop

Igneous Cores can be farmed by summoning and defeating Heralds of Malphas inside Arcane Tremors at World Tier 4. Spend Elemental Cores and Shattered Stone at Braziers to summon a Herald of Malphas.

However, do note that unlike Pearls of Warding, Igneous Cores are not guaranteed drops. They only have a rare chance to drop after beating a Herald of Malphas.

Arcane Tremors Guide and Rewards

Defeat the Son of Malphas Mini Boss at WT4

D4 Season 3 - Son of Malphas Igneous Core Drop

Alternatively, players can look to defeat the Son of Malphas at World Tier 4 to get a few Igneous Cores. However, do note that this mini boss is a random encounter inside Nightmare Vaults and Arcane Tremors which means you cannot target farm it.

The Son of Malphas is a special mini boss similar to the Butcher. It will have a very high HP pool and powerful attacks that can one-shot unprepared characters. Challenge him at your own risk.

How to Use Igneous Cores

Used to Open the Vault of the Loom in World Tier 4

Vault of the Loom Entrance Fee ・x7 Igneous Cores
・x250 Shattered Stone

Igneous Cores are used to open the Vault of the Loom endgame dungeon in World Tier 4 (after beating the Season 3 Questline). Previously, you had to use Pearls of Warding instead of Igneous Cores to open the vault.

Allows You to Challenge the Echo of Malphas

The final room of the vault will contain the Loom. This massive arena is where you can challenge the Level 100 Echo of Malphas for a chance to get the Evernight and Genesis Unique Tuning Stones.

What are Igneous Cores?

New Boss Material Introduced in Patch 1.3.0a

Igneous Cores are the developers' answer to the problem of Pearl of Warding usage at World Tier 4. Previously, endgame players would hoard Pearls for the Vault of the Loom encounter rather than using them for Zoltun's Warding stacks.

In order to alleviate this resource pain point, Patch 1.0.3a introduced Igneous Cores as the new key item needed to enter the Vault of the Loom. This ensures that Pearls are now used solely for Zoltun's Warding.
