Rescue is the main gacha system in Chaos Zero Nightmare, allowing players to recruit Combatants, obtain Partners, and collect special Prism Modules. Although these rewards all come from different Rescue banners, they don't share exactly the same currencies, probabilities, or guarantee rules. Knowing how each system works can make a noticeable difference when planning your next pulls.
For players managing their progression through different Chaos Zero Nightmare Accounts, understanding the banner system is especially useful. Instead of spending Crystals whenever a new character appears, we recommend learning how pity works, which banners have separate counters, and what happens when you miss a featured reward.
Understanding the Rescue System and Currencies
Chaos Zero Nightmare uses the term Rescue for its gacha system. There are two main character-related reward categories:
- Combatants: Playable characters who take part in battles. They come in 4-star and 5-star rarities.
- Partners: Support units equipped to Combatants. They have 3-star, 4-star, and 5-star rarities.
The game also offers Prism Modules through a separate Rescue category. These provide card-related visual effects rather than additional playable characters.
Before choosing a banner, it's important to understand which currency it accepts.
| Currency | Main Purpose | Cost |
|---|---|---|
| Crystals | Premium currency used to obtain Rescue items | Varies |
| Rescue Anchor | Standard and beginner Rescues | 160 Crystals |
| Signal Amplification Anchor | Featured character and Partner Rescues | 160 Crystals |
| Prism Lens | Prism Module-related Rescues | 120 Crystals |
For example, a ten-pull on a featured Combatant banner costs 10 Signal Amplification Anchors, equivalent to 1,600 Crystals.
One detail we always recommend checking is the actual item required by each banner. Rescue Anchors and Signal Amplification Anchors have the same listed Crystal cost, but they aren't interchangeable.
All Chaos Zero Nightmare Banner Types
Not every Rescue banner serves the same purpose. Some are designed for beginners, while others focus on expanding your Combatant roster or improving existing teams with Partners.
Here's a quick comparison of the main banner categories.
| Banner | Main Rewards | Special Feature |
|---|---|---|
| Special Signal Selective Rescue | Standard 5-star Combatant | Beginner selection system |
| Normal Combatant Rescue | Combatants | Standard character pool |
| Normal Partner Rescue | Partners | Standard support pool |
| Amplified Distress Signal | Featured Combatants | Rate-up character and 50/50 |
| Featured Partner Rescue | Featured Partners | Featured 5-star guarantee |
| Prism Module Rescue | Prism Modules | Selected character-related rewards |
Special Signal Selective Rescue
The beginner banner is worth checking before spending resources elsewhere.
Unlike regular Rescues, Special Signal Selective Rescue lets players review multiple sets of results before making their final selection.
According to the in-game description provided in the source material, players receive two temporary save slots and can perform up to 20 attempts, with each attempt consisting of ten Rescues. They then select a Rescue record.
The important part is that the banner ends after a record is selected.
Our recommendation is to avoid rushing this decision. Compare the available 5-star Combatants and consider which one will be most useful for your early progression.
Standard Combatant and Partner Rescues
These two banners provide a more straightforward way to expand your collection.
Normal Combatant Rescue focuses on standard Combatants without featuring a specific rate-up character. It is useful when you still need more playable units to build a functional team.
Normal Partner Rescue follows a similar structure but focuses on Partners. These units can improve the performance of Combatants, making them more valuable once you already have a reasonable character selection.
For most beginners, we suggest prioritizing Combatants first. Having enough playable characters gives you more flexibility when building teams for different encounters.
Rescue Rates, Soft Pity, and Hard Pity Explained
Understanding the probability system is more important than simply counting how many Crystals you have.
Most character-related Rescue banners use a 1% base probability for their featured rarity's 5-star reward and a 6% probability for 4-star Combatants or Partners. They also provide a 4-star-or-higher guarantee within every ten pulls.
However, the pity system determines how your chances change after repeated unsuccessful attempts.
5-Star Rates and Pity
The following table summarizes the published rates and guarantees described for the different Rescue categories.
| Banner Type | Base 5-Star Rate | Soft Pity | Hard Pity |
|---|---|---|---|
| Normal Combatant | 1% | From pull 58 | 70 pulls |
| Normal Partner | 1% | From pull 58 | 70 pulls |
| Featured Combatant | 1% | After 57 unsuccessful pulls | 70 pulls |
| Featured Partner | 1% | From pull 58 | 70 pulls |
| Prism Module | 3% | From pull 58 | 70 pulls |
These figures reflect the published rules described in the source material. Always check the current Probability Info screen, especially for seasonal banners and special Rescue events.
Soft Pity means the probability of obtaining a 5-star reward starts increasing after a certain number of unsuccessful pulls. The Normal Combatant Rescue, for example, describes a 4.5-percentage-point increase with each subsequent pull beginning at pull 58.
Hard Pity is the maximum number of pulls required to receive a 5-star reward under the stated banner rules.
In the character and Partner systems covered here, that limit is 70 pulls.
There is also a separate 4-star guarantee. Even if you don't obtain a 5-star reward, every ten pulls guarantees at least one 4-star-or-higher reward on the relevant regular Rescue banners.
Do Different Banners Share Pity?
This is one of the most important questions when planning your pulls.
The standard Combatant banner has its own pity counter, separate from the Partner banner and other Rescue categories. Featured banner rules also need to be checked by category.
We recommend tracking your pulls individually rather than treating every Rescue as part of one shared counter.
A useful habit is to record three things:
- Which banner category you pulled on.
- How many unsuccessful pulls you have accumulated.
- Whether you have already missed a featured 5-star reward.
This makes it easier to decide whether saving your resources for another banner is worthwhile.
Featured Banners: 50/50 and Guaranteed Rewards
Featured Rescues are generally more attractive when you're targeting a specific Combatant or Partner.
However, the guarantee rules are different between these two categories.
Featured Combatant Rescue
Amplified Distress Signal banners increase the appearance rate of selected Combatants.
When you obtain a 5-star Combatant on a regular featured banner, there is a 50% chance that it will be the featured character.
If you receive a standard 5-star Combatant instead, you lose the 50/50.
Under the published rules, your next 5-star Combatant from that banner category is guaranteed to be the featured character.
This distinction matters because a 70-pull guarantee does not automatically mean you'll get the featured character within those 70 pulls. It guarantees a 5-star reward, while the featured guarantee depends on the 50/50 result.
This distinction is particularly important when planning a large number of pulls. The published Combatant rate-up rules describe a 50/50 chance on the first 5-star and a guaranteed featured Combatant on the subsequent 5-star if the first one is not the rate-up target.
Featured 4-star Combatants also have their own rate-up rules. If a 4-star reward isn't one of the featured options, the next 4-star is guaranteed to be among them under the described rules.
Featured Partner Rescue
Featured Partner banners use Signal Amplification Anchors as well, but their main rewards are support units.
The biggest difference is the 5-star guarantee.
According to the published banner rules, every 5-star Partner obtained through the featured Partner Rescue is the rate-up Partner.
That means players don't face the same 5-star 50/50 uncertainty described for regular featured Combatant banners.
For players who already have their preferred Combatants, this can make featured Partner banners an appealing way to improve an existing team.
One important exception deserves attention: seasonal banners may use separately listed rules. For example, the Rossweisse seasonal banner should not automatically be assumed to follow every guarantee or carryover rule of a normal featured Combatant banner.
Always read its Probability Info before spending your saved Anchors.
Duplicate Rewards, Prism Modules, and Crystal Spending Tips
Rescue rewards don't stop being useful when you obtain duplicates. Chaos Zero Nightmare also provides exchange currencies that let players turn repeated pulls into additional resources.
Memory Archive Exchange
The Memory Archive Exchange uses two main currencies.
| Exchange Currency | How to Obtain It | Main Uses |
|---|---|---|
| Moments of the Radiant Traveler | 3-star Partners | Monthly Rescue item purchases |
| Moments of the Radiant Hero | Duplicate 4-star and 5-star Combatants or Partners | Rescue items, Partners, Memory Codes, and upgrade materials |
Moments of the Radiant Traveler are awarded when obtaining 3-star Partners. The described exchange allows players to purchase five Rescue Anchors and five Signal Amplification Anchors for 90 Moments.
Moments of the Radiant Hero are more valuable for certain exchanges because they come from higher-rarity duplicate rewards.
For example, the published exchange information lists:
- 10 Moments for one Rescue Anchor or Signal Amplification Anchor.
- 300 Moments for a standard 5-star Partner.
- 400 Moments for a 5-star Combatant Memory Code.
These rewards provide another reason to pay attention to duplicate pulls. Instead of viewing every repeated reward as completely wasted, consider how it contributes to your next exchange purchase.
What About Prism Module Rescue?
Prism Modules belong to a separate reward category.
They are connected to card animations and visual presentation rather than providing new Combatants or Partners.
The described system lets players select a desired Prism Module associated with a standard 5-star Combatant. It also uses a different Rescue currency and has its own probability rules.
For new players, we recommend treating Prism Modules as an optional collection goal.
If your roster is still missing important Combatants, spending Crystals on visual rewards is usually less useful than improving your available team.
Our Team's Crystal Spending Strategy
After looking at the different banner categories, we recommend following a simple priority system.
- Check the beginner banner first. Review the available results before selecting your first 5-star Combatant.
- Build a functional Combatant roster. A wider selection of playable characters gives you more flexibility than chasing every featured release.
- Save for specific rate-up targets. Don't spend Signal Amplification Anchors simply because a new banner appears.
- Understand the 50/50 before pulling. A 5-star guarantee and a featured character guarantee are not necessarily the same thing.
- Treat Partners as team upgrades. Consider featured Partners when you already have Combatants worth investing in.
- Leave Prism Modules for later. Their visual benefits are less important than roster development for most beginners.
We also suggest avoiding unnecessary Crystal conversions. Keep track of your available Anchors and the banner categories they belong to before making a purchase.
Summary
Chaos Zero Nightmare's Rescue system offers several ways to expand your collection, but understanding the differences between banners is essential for efficient resource management.
The beginner Selective Rescue provides an opportunity to choose an early 5-star Combatant, standard Rescues help expand your roster, and featured banners let you target specific Combatants or Partners.
The biggest detail to remember is that a 5-star guarantee doesn't always mean a featured character guarantee. The 50/50 system on Combatant banners and the guaranteed featured Partner rules can lead to very different results.
Our advice is to build your core roster first, save Crystals for banners that match your team needs, and always check the current in-game Probability Info before committing to a large number of pulls.
FAQ
1. How many pulls are needed to guarantee a 5-star in Chaos Zero Nightmare?
The described character and Partner Rescue systems have a hard pity limit of 70 pulls. Prism Module Rescue also has a separate 5-star guarantee under its published rules.
2. Does the featured Combatant banner have a 50/50 system?
Yes. On a regular featured Combatant banner, the first 5-star has a 50% chance of being the featured character. If you receive a standard 5-star instead, the next 5-star in that banner category is guaranteed to be featured under the described rules.
3. Are Combatant and Partner pity counters shared?
No. The standard Combatant and Partner Rescue counters are separate. You should track each banner category independently and check the current banner information for any special carryover conditions.
4. Should beginners pull for Combatants or Partners first?
We generally recommend building a functional Combatant roster first. Partners become more valuable once you have suitable Combatants to equip them to.
5. Are Prism Modules worth spending Crystals on?
They are worth considering if you enjoy collecting card-related visual rewards. However, they don't replace Combatants or Partners, so most new players will benefit more from developing their roster first.
