Welcome to our Diablo 4 Codex of Power Guide.
In this guide we will explain what the Codex of Power is, and how to use it to enhance your character’s gear.
What is the Codex of Power in Diablo 4?
The Diablo 4 Codex of Power is a collection of powerful bonuses, called Legendary Aspects, that can be applied to your gear.
Your Codex of Power will start off empty, however you can fill it with new Legendary Aspects by completing dungeons throughout the world of Sanctuary. Each dungeon has a Legendary Aspect associated with it.
Some Legendary Aspects are unique to a specific class, however others can be used by any class. In addition, the type of gear that a Legendary Aspect can be applied to depends on its type. There are the following types available:
- Defensive Aspects: Used for Off-Hand, Helm, Chest, Pants and Amulet
- Offensive Aspects: Used for One-Handed Weapons, Two-Handed Weapons, Gloves, Amulet and Ring
- Resource Aspects: Only available on Rings
- Utility Aspects: Used for Off-Hand, Helm, Chest, Boots, Gloves and Amulet
- Mobility Aspects: Used for Boots and Amulet
Note that if a Legendary Aspect is applied to a two-handed weapon, its effects will be 100% stronger, and if it is applied to an Amulet then it will be 50% stronger.
How to Access the Codex of Power
You can view your Codex of Power at any time by pressing the Y button to open your Collections.
You can use this screen to preview the effects of all of your unlocked Legendary Aspects.
To unlock more Aspects, keep playing through dungeons throughout Sanctuary. Each dungeon you complete will award you with a new Legendary Aspect.
How to Use Legendary Aspects in Diablo 4
To apply (imprint) unlocked aspects to your equipment, you’ll need to visit an Occultist NPC. These can be found in major settlements around Sanctuary. The image below shows the location of the Occultist in Kyovashad.
You can only imprint Aspects onto items of Rare or Legendary quality. After imprinting a Rare item with an aspect, its quality will upgrade to Legendary. Imprinting a Legendary item with an aspect will not change its quality, but the existing Aspect will be replaced.
The Occultist also offers another service that allows you to imprint aspects that you do not have unlocked in your Codex of Power. This is known as Extracting.
How to Extract Legendary Aspects in Diablo 4
If you find a piece of Legendary gear with an Aspect that you want to transfer to another piece of your gear, then you can visit the Occultist and use the Extract Aspect service.
This will destroy the item, but grant you an Aspect of its power – a single-use item that you can use to apply the same Aspect to another valid piece of gear (see the requirements mentioned above).
This service is useful if you find a Legendary item with an Aspect that you like, but do not yet have unlocked in your Codex of Power.
