What is Zero System?
A High-Difficulty Version of Chaos
The Zero System is basically the same as Chaos Manifestation. However, restrictive conditions have been added to the existing Chaos, making it more difficult. As a result, the created Save Data is also more valuable.
Select a Codex (Conditional Chaos)
Challenges in the Zero System begin with creating a conditional Chaos called a Codex. When you create a Codex, you can choose from three types, each with different conditions and levels.
Upgrades are Possible
In the Zero System, you can obtain a special item called a Chaos Orb. By using this item, you can update features that give you an advantage in the Zero System, such as Status Upgrades.
Obtain Rewards from the Chaos Matrix
In the Chaos Matrix, you can get rewards such as Crystals and upgrade materials based on the total number of Chaos Orbs you've collected. Additionally, these rewards are seasonal and change periodically.
Get Legendary Memory Fragments
In the Zero System, you can also obtain rewards by using the Loot Certification Card. In the Zero System loot, Legendary Memory Fragments also appear.
Chaos Manifestation or Zero System Farming?
Choose Zero System if You Can Clear It
Since the Zero System also increases Chaos Exploration, it is like a superior version of Chaos Manifestation. The benefits of farming the Zero System are great, so if you can clear it consistently, you should proactively farm the Zero System.

Character Enhancement GuideFarm to Collect Chaos Orbs
Once you are able to clear the Zero System, repeatedly farm it to collect Chaos Orbs. You can also obtain rewards from the Chaos Matrix.
Escape Is Optional If You Can't Win
Chaos Orbs can also be obtained by escaping. If you encounter a battle you cannot win, escape and Retrieve the Chaos Orbs.
Areas Where Chaos Orbs Can Drop
In the Zero System, areas where Rare species that yield Chaos Orbs appear also exist. Pay attention when selecting your route.
Use Upgrades on High-Difficulty Challenges
Once you have collected Chaos Orbs, use upgrades to gain an advantage in your runs. As you advance your upgrades, you will be able to consistently clear even high-difficulty Codexes.
