Diablo 4 Guide: Farming Igneous Core for the Ultimate Challenge


In the ever-evolving world of Sanctuary, Diablo 4 Season 3 introduces a formidable new Construct threat, compelling players to upgrade their Seneschal Companions for a chance to explore the Vaults and confront Malphas. However, for those daring enough to face the Uber version of this demonic adversary, gathering Igneous Cores becomes a crucial task. Here's your comprehensive guide on how to farm Igneous Core in Diablo 4, unlocking the path to the Vault of the Loom and the ultimate showdown with Uber Malphas.

Understanding Igneous Cores

Igneous Cores are rare materials essential for opening the Vault of the Loom Dungeon, leading players to the Uber Malphas boss fight in Diablo 4 Season 3. Defeating Uber Malphas rewards players with the most coveted Tuning Stones for Seneschal Companions, alongside unique items and legendary aspects. Introduced in the 1.3.0 update as a replacement for Pearls of Warding, these cores are now the key to summoning Uber Malphas, offering players the chance to obtain the game's rarest Tuning Stones and other valuable rewards.

Farming Igneous Cores

The most efficient method to acquire Igneous Cores involves farming Heralds of Malphas. Follow these steps to summon and defeat these formidable foes:

  1. Locate Igneous Obelisks scattered around Sanctuary.
  2. Deactivate these obelisks to earn Elemental Cores.
  3. Collect Shattered Stones, which drop from enemies within the Vaults.
  4. Combine 3 Elemental Cores and 50 Shattered Stones at Voltaic Braziers to summon a Herald of Malphas. Defeating this Herald yields Igneous Cores.

To challenge Uber Malphas in the Vault of the Loom, players must gather 7 Igneous Cores and 250 Shattered Stones.

Alternative Summoning Method

Players can also attempt to summon the Son of Malphas, who randomly appears during Arcane Tremors and can invade any Nightmare Vault. While he is often found around the Seat of the Heavens (Fractured Peaks), his ability to one-shot opponents makes him a risky target, especially for solo players. Focusing on farming the Herald of Malphas is recommended for those venturing alone.

Preparing for the Challenge

Collecting Igneous Cores and facing Uber Malphas is no small feat. Players should ensure their Seneschal Companions are fully upgraded and that they have mastered their chosen class's combat strategies. Whether you're a Necromancer, Barbarian, Druid, or Sorcerer, being well-prepared is key to overcoming the challenges that lie within the Vault of the Loom.


Farming Igneous Cores in Diablo 4 Season 3 opens the door to some of the game's most thrilling encounters and rewarding experiences. By following this guide, players can confidently prepare to face Uber Malphas, earning themselves powerful companions and legendary loot. As always, stay tuned for more guides and tips to help you navigate the dangers of Sanctuary and emerge victorious.
