Zero System guide for Chaos Zero Nightmare (CZN). See Zero System modes explained, upgrades, difficulty modifiers, chaos orbs, codex records, chaos matrix, and exploration rewards.
CZN Zero System Challenge
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 more valuable, and you can create powerful ones.
Select a Codex (Conditional Chaos)
Challenges in the Zero System begin by creating a conditional Chaos called a Codex. When you create a Codex, you can choose from three types, each with different conditions and levels.
You Can Also Take on Seasonal Chaos
Sometimes, past Seasonal Chaos that were held as Events will appear. You can also obtain equipment and Cards exclusive to Seasonal Chaos.
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.
CZN Zero System Farming
Seasonal Chaos is Recommended
In the Seasonal Chaos held during Galactic Disaster, you can create exclusive Save Data. Since you can also get Chaos orbs and there are weekly achievement rewards, it is recommended to challenge the Seasonal Chaos while it's being held.
Galactic Disaster GuidePrioritize Than Chaos Manifestation
The Zero System also increases Chaos Exploration, making it like a superior version of Chaos Manifestation. The benefits of farming the Zero System are also great, so if you can clear it consistently, you should actively farm the Zero System.

Train Your Characters
The Zero System is difficulty 5 or higher, and enemies are also early level 40 or higher. Be sure to fully train your character's level and Potential before challenging it.
Farm to Collect Chaos Orbs
Once you can clear the Zero System, repeatedly farm it to collect Chaos orbs. You can also obtain Chaos Matrix rewards.
Escaping is an Option if You Can't Win
Chaos orbs can also be obtained by escaping. If you encounter a battle you can't win, escape and Retrieve your Chaos orbs.
Areas Where Chaos Orbs Can Drop
In the Zero System, areas will also appear that feature Rare Species from which you can obtain Chaos Orbs. Pay attention when choosing a route.
Move Up to Higher Difficulty Levels
Once you've collected Chaos orbs, use upgrades to progress more easily. As you advance your upgrades, you'll be able to consistently clear even high-difficulty Codexes.
