Diablo 4: Codex Of Power [Explained]

In our guide on the Diablo 4 Codex Of Power, we explain the Codex Of Power system and how it uses Legendary Aspects.

The Diablo 4 Codex Of Power is a system that allows players to collect Legendary Aspects. These Legendary Aspects can then be used on your character’s equipment to make your character more powerful. And yes, some Legendary Aspects are class and build-specific, while others can be used on any build.

Key Highlights
  • The Codex Of Power is a new system or feature added in Diablo 4.
  • It allows players to collect and imprint Legendary Aspects. However, these can only be implemented on Rare or Legendary pieces of equipment.
  • Not all Legendary Aspects are included in the Codex Of Power, and also, every time, the lowest possible variant of an aspect is used.
  • However, it is an infinite source of Legendary Aspects once you have collected an aspect.
  • It is a feature that each player will likely make use of as it helps players to become that much more powerful and customizable with their characters.

The Codex Of Power is essentially a list of Legendary Aspects that you earn throughout Diablo 4. However, normally while using a Legendary Aspect on a piece of equipment, the Aspect is destroyed, but that is not the case for the Aspects that are collected in the Codex Of Power. You can make use of the Aspects in the Codex Of Power as many times as you like.

And the Codex Of Power can only be used on Rare or Legendary pieces of equipment. Furthermore, to imprint the aspects on the equipment, you will have to make use of the Occultist. Also, whenever you use the aspects on a rare piece of equipment, the equipment turns legendary. While if you use it on a piece of legendary equipment, then only the power is changed.

Drawbacks Of The Codex Of Power

However, the developers had to implement a limiting factor in the system to restrain it from being too powerful. And these restrictions are as the following:

  • The first drawback is that the Codex Of Power will always implement the lowest possible variant of power. For example, you have an aspect that allows you to deal 20% to 40% extra damage. In this case, the Codex Of Power will always implement the 20% bonus. While if you find a 40% aspect, you can implement the 40% one on your equipment.
  • The second drawback is that not all of the Legendary Aspects are available in the Codex Of Power. So you might not be able to make use of this system if you are looking for a specific aspect.

Now, as we mentioned before, to make use of the Codex Of Power, you will first need to get hold of a variety of Legendary Aspects. And the way you do that is by completing dungeons. However, you will have to do it twice, as the first time you complete a dungeon, it is unlocked for later use. 

And when you make use of it later, you will be able to know which Legendary Aspect you will gain as a reward. Thus you will be able to pick and choose the aspect that you require, but only after you have completed the dungeon for the first time. Also, if you need help locating the dungeons, then make use of our Diablo 4 All Dungeon Locations guide. Furthermore, you also might want to take a look at our Diablo 4 All Waypoints guide, as it will help you to move more efficiently between the dungeons.


In conclusion, the Codex Of Power is an excellent system introduced in Diablo 4 as it allows the players a sense of customization. This is because the players are able to make use of it to mix and match. They are able to implement their desired aspects on their equipment, and it is a great way to make their build more efficient and powerful.

And once Diablo 4 is released, the players will truly appreciate the depth that the Codex Of Power provides in combination with other features and systems. And with this, we bring our guide on Diablo 4 Codex Of Power to an end.
