While Diablo 4 Season 3 has sparked a division within the community due to its emphasis on traps and hazards, there's no denying the game's steady improvement over time, marked by the introduction of numerous endgame activities. These include the new Arcane Tremor world events, Vault dungeons, and an enjoyable seasonal questline.

The central antagonist for this season goes by the name Malphas, whose boss battle awaits not only at the culmination of the seasonal questline but also in the endgame, featuring a modified Uber version.

In this guide, we will comprehensively discuss the summoning process, location for the Diablo 4 Season 3 Uber Malphas boss fight, and provide a complete list of known Diablo 4 Items obtainable by defeating him.

The Whereabouts Of Uber Malphas & The Conditions For Summoning

To summon and confront Uber Malphas, you'll need to journey to his domain, the Vault of the Loom, situated in the central northern part of the main hub for Diablo 4 Season 3 - Gatehall.

Upon entering the Vault of the Loom, you'll encounter a locked door and an altar. Accessing Uber Malphas' dungeon involves the use of 2 distinct resources:

• 7x Igneous Core
• 250x Shattered Stone

Shattered Stones are readily available and can be farmed in Diablo 4 Season 3, dropping from any of the new construct enemies and elites found in the Vault dungeons or Arcane Tremor events. You can also acquire them by picking up a Governing or Tuning Stone that is already at its maximum level.

Obtaining Igneous Cores is a bit more challenging. The primary method is by defeating the Heralds of Malphas elites, summonable at different Braziers during the Arcane Tremor events.

The second method involves defeating the Son of Malphas elite, which, much like the Butcher, can randomly appear in any of the Vault dungeons and sometimes near the Arcane Tremor events in the open world.

Upon opening the door in the Vault of the Loom, you must clear four smaller versions of Vault dungeons before facing Uber Malphas at the culmination.

What Can You Gain After Defeating Uber Malphas?

Uber Malphas sets himself apart from other endgame bosses by lacking a dedicated pool of Unique items for drops.

He has the potential to drop Rares, Legendaries, and random Uniques, similar to any other monster in World Tier 4, with a slight chance of them reaching Item Power 925. The primary incentive to farm Uber Malphas lies in the Unique Tuning Stones exclusive to him.

Genesis and Evernight, the game's most potent Tuning Stones, can significantly enhance your Seneschal Construct. Blizzard has disclosed the drop rates for these Unique Tuning Stones:

• Uber Malphas: 0.5% chance to drop.
• Wardwoven Chests After the Boss: 3% chance to drop.

This encapsulates all the crucial information regarding locating, defeating Uber Malphas, and delves into his specific loot table. The Unique Tuning Stones he can yield are exceptionally potent, making it advisable to farm him if you aim to compete in the forthcoming Gauntlet leaderboards.
