Chaos Zero Nightmare - Potential Guide How to Upgrade
Potential is a permanent progression system in Chaos Zero Nightmare (CZN) that lets you enhance your Combatants with lasting stat boosts and card upgrades. Learn how Potential works, how to unlock it, and where to farm the materials needed to upgrade your Combatants.

What is Potential?

Permanent Power-Ups

Chaos Zero Nightmare - Hugo Potential
Potential is a permanent character progression tree for each Combatant that gives long-term boosts. Potential lets you permanently strengthen your characters beyond run-based upgrades. Every node you unlock grants lasting benefits, from higher stamina and attack to enhanced card effects or passive bonuses.

Upgrades Basic Card Effects

Chaos Zero Nightmare Potential Upgrade

The 03-1 potential allows all combatants to upgrade their basic cards with new effects, new glossary tags, or boosted stats for their current effects. The 05-1 Basic Card Upgrade node further enhances the basic card’s effect based on how high a specific stat is. For example, Mei Lin gains a 5% increase to her Strike card, plus an additional 5% if her Attack stat is over 500.

How to Unlock Potential

Use Growth Stones to Unlock and Upgrade Potential

Growth Stones are the attribute-typed materials (Order, Passion, Justice, Instinct, Void, etc.) used to unlock nodes on a Combatant’s Potential tree. They come in rarities and some nodes require specific attribute stones or higher-rarity versions.

List of All Items

Promote Your Combatants to Allow Unlocking Further Potential Nodes

Chaos Zero Nightmare - Level Up Promotion
Before you can start unlocking Potential, your Combatant must reach level 20. This milestone unlocks their Potential tree, allowing you to invest in permanent stat boosts and skill upgrades that persist across runs.

Once unlocked, open the Potential tab in the Combatant menu to access the first two nodes — Combat Epiphany and Upgrade Card. Higher-tier nodes require greater Combatant and Leader Levels, so be sure to level them up before continuing through the tree.

Choose the Simulation stage that matches your Combatant’s attribute to maximize efficiency. Higher Simulation levels yield higher-quality stones, so push as far as your team can handle for better rewards.
