Occultist Guide for Diablo 4 (Season 3)

Learn how unlock the Occultist, and craft your way towards ultimate power!




Updated: Posted:



The Occultist is an important NPC during your adventures across Sanctuary. In this guide, we will explore the advantages of extracting or imprinting Legendary aspects into gear, alongside the art of enchanting, and the process of crafting and salvaging Sigils.

How to Unlock the Occultist

The Occultist can be unlocked through two distinct methods: Firstly, by using the character who acquires the initial legendary aspect from the Codex of Power, or alternatively, additional characters can unlock the Occultist once they reach Level 25. 

For more information on The Codex of Power, Legendary Apsects, as well as how to Extract and Imprint Aspects, please refer to our dedicated guide (link below):

Legendary Aspect and Codex of Power Guide

The Occultist can be found in any major town within each zone, easily identified on the map by a specific symbol, as shown below:


The Occultist is easily one of the most significant NPCs, enabling players to greatly enhance their chharacters power.

Throughout your journey across Sanctuary, you will encounter a multitude of legendary powers known as Legendary Aspects. Each dropped legendary gear item will have a random Legendary aspect. Additionally, specific dungeons may yield certain Aspects, which will then automatically be added to the Codex of Power for future use.

These Aspects can be extracted from legendary gear and subsequently imprinted onto other legendary or rare gear. Once an aspect is imprinted, rare gear will also turn into a legendary item.

It is also worth noting, that any Aspects acquired, and gathered within the Codex of Power, will be accessible across your entire roster of characters of the same realm.

Aspects are categorized into five distinct types, and they can only be imprinted onto specific gear slots, as follows:

  • Offensive – Amulet, Weapon, Gloves, Ring
  • Defensive – Shield, Helm, Chest, Pants, Amulet
  • Utility – Shield, Helm, Chest, Amulet, Gloves, Boots
  • Mobility – Amulet, Boots
  • Resource – Ring

Enchanting and Rerolling

The Occultist also offers the opportunity to reroll unwanted affixes on Rare or Legendary gear. However, be careful, because once an item has been enchanted (re-rolled), it becomes account-bound if it was not already.

When rerolling, one stat per item can be modified. Nevertheless, you have the ability to reroll it indefinitely. This system proves highly efficient during the endgame phase, allowing you to elevate good legendary items to top-tier status. For instance, if an item has three out of four perfect affixes, you can reroll the fourth affix to create a truly flawless item with all four affixes aligned.

Enchanting gear requires both gold and specific materials. Rare items need Veiled CrystalVeiled Crystal, whereas legendaries require Veiled CrystalVeiled Crystal, and Fiend RoseFiend Rose.

It is important to note that certain affixes cannot coexist, so it is vital to avoid attempting to roll for a stat that cannot be obtained on a particular piece of gear.

After enchanting, you are presented with the option to keep the modification or revert to the old affix. Regardless of the choice made, the materials will be consumed, and the item will be considered enchanted. However, in both cases, it is possible to continue rerolling for a better affix on the same item.

Nightmare Sigils

Sigils function as keys that come into play once World Tier 3 is reached, allowing access to Nightmare Dungeons. You can read more about Nightmare Dungeons and Sigils in our separate guide.

Nightmare Dungeon Guide

The Occultist provides the option to either salvage unwanted Sigils or craft new ones. However, before you can craft or salvage Sigils, you first need to complete a Nightmare Dungeon of Tier 3 or higher. The tier of Nightmare Sigils rewarded from Whisper Caches will always be within 5 Levels of the highest-level Nightmare Dungeon you have completed.

Please note that the Nightmare Dungeon Tier is distinct from the World Tier difficulty. The two are not related. However, in order to craft Sacred and Ancestral Sigils, you must first unlock World Tier 3 (for Sacred) and World Tier 4 (for Ancestral Sigils).

Through the use of Sigils, normal dungeons can be transformed into Nightmare Dungeons (remember to use it before entering a dungeon to transform it into a Nightmare Dungeon). This transformation then introduces specific “afflictions” to the dungeon, increasing its danger level while also boosting the rewards and their rarity. Sigil afflictions can impact the character, enemies, or the dungeon environment.

There are two types of sigils available, each corresponding to a specific tier (Sacred Sigils will provide World Tier 3 Nightmare, and Ancestral Sigils will open World Tier 4, Torment difficulty) of gameplay:

Sigils can naturally be acquired while completing the Tree of Whisper quests or running Nightmare Dungeons. Each Sigil corresponds to a specific Nightmare Dungeon (the dungeon’s name will be indicated on the Sigil).

If you wish to farm a particular Dungeon as a Nightmare version or desire to upgrade to higher tier Sigils, visit the Occultist to salvage old or unwanted Sigils. Subsequently, you have the option to craft new Sigils of the desired tier. This allows for Sigil creation according to preferred dungeon choices, and desired difficulty levels.

Season Mechanic

During Season 3, the Occultist will also allow you to craft Vault Sigils, which are used to enter Nightmare Vaults. You can find a new tab at the Occultist NPC, where you can spend Pearls of Warding during the Season of Construct, in order to craft a Vault Sigil.
