Chaos Zero Nightmare Save Data Guide – Everything You Need To Know
What Are Save Data
The Save Data system in Chaos Zero Nightmare prefers to the value of a card deck build that players can have when building a character. Each character can have multiple save data decks with different cards and values to be used in multiple different game modes like Basin, general farming or event challenges.

To build a Save Data card deck for each character, you will need to bring them to the different Chaos Zones or Zero System and fight in the roguelike gamemodes in order to add, remove or strengthen the different cards in the deck. Upon clearing the Chaos run to a certain point, players will be able to take out the Save Data deck of the current Chaos Run outside of the game mode to be used in other contents.
Each Card in a Save Data card deck is assigned a specific value, and each interaction with a character’s card like duplicate, remove, epiphanies, etc. will affect the value of the card and the overall value of a deck. If the value of the deck exceeds certain conditions, your Save Data will be modified compared to the ones you have during the Chaos run.

Chaos Save Value & Card Value Points
When challenging the different Chaos levels and Zones, before entering the stage, players will be able to check the Save Data Value of each Chaos. The higher the Chaos overall challenge level, the higher the Save Data Value of the Chaos.
The Save Data Value of the Chaos are signified by a Tier system, going from Tier 1 to Tier 18. The higher the tier, the more cards with high values can be added to a character’s card deck and the higher the maximum value of a characters’ Save Data Card Deck is.

Each tier’s maximum Save Value for the card deck is the Chaos Save Value x 10 + 20. So for example, if the Save Value tier is 8, then the maximum Save Data Value for each characters’ deck at the end of the Chaos will be 8×10+20 = 100 points.
How Save Data Card Value Are Calculated
Here’s an overview of how different interactions in the Chaos can affect the overall value of a card deck and how players can calculate the card deck’s value before exiting the chaos to maximize a card deck’s Save Data Value:
– A character’s basic 8 cards are considered base cards, so adding them into your deck through initial epiphanies costs 0 points.

– Each normal Epiphanies listed on the cards for the 8 basic cards for each character’s deck, are valued at 0 points and do not affect the value of the deck.

– For each Divine Epiphanies or Legendary Epiphanies, regardless of the card, it adds 20 points into the deck.

– For each Neutral card added to the deck, they are valued at 20 points each.If you convert a card into a Neutral card, their value is 10 points. If the Neutral Card triggers an Epiphany, then the card value is increased to 30 points, 40 points for if its a Divine Epiphany.

– When copying cards, the cost of copying the cards increases with each time you copy. The 1st copy cost 0 points, the 2nd copy cost 10 points, the 3rd copy cost 30 points and onwards.

For example, if you copy a basic card with Divine Epiphany (which have a value of 20 points), the first copy of that card will have a value of 20, while the 2nd copy of that card will have a value of 30 (the initial 20 card value + 10 points of the copy cost), for a total of 50 points value for the 2 copies of the initial card.
– When removing cards, the cost of each removal increases similarly to when you copy a card, with a 10 points cost at the 2nd removal, 30 at 3rd removal, 50 at 4th removal and onward. However, if players remove 1 of the 8 basic cards in a character’s card deck, regardless of the removal cost, each basic card removed adds 20 points into the total.
For example: if the first card removed in the deck is a basic card, then its worth 20 points (20 points for removing basic card + 0 points cost for 1st removal), if the 2nd card removed in the deck is another basic card, the cost will be at 30 points (20 points for removing basic card + 10 points cost for 2nd removal) and onward.
– Forbidden Cards are worth 20 points each in the total and Monster Cards are worth 80 points each.

At the end of a Chaos Run or when you retreat from the Chaos, if the Card Values in your character’s Save Data Card Deck is higher than the maximum Save Value of the Chaos, the card deck’s value will be balanced by the game removing high value cards, demoting the effects of some cards and add back some low value cards into the deck to balance out the value of the Save Data deck.
Tip & Tricks To Build The Best Character Decks
Equipment Does Not Affect Save Data Value
When doing Chaos Runs, players will be able to equip each character with 3 different pieces of equipment to boost their damage output and provide additional effects. These equipment will be carried out of the Chaos alongside the character’s Save Data Deck at the end of the Chaos.

However, please note that these equipment does not contribute to the total value of the card deck, so players can aim for the best equipment build without worrying about the equipment affecting the final Save Data card deck you will receive.
Focus On Building A Single Character At A Time
With how the Save Data system works, players can build 3 different characters’ card decks with each run of Chaos. However, it is extremely recommended that you focus on building only 1 character at a time when doing a Chaos Run, to maximize the value of each characters’ deck.
Due to how limited a Chaos Run is and how you only have a set amount of opportunities to Remove and Duplicate cards, focus on building a character each Chaos run by optimizing their Save Data by removing useless cards and duplicating powerful cards to have a strong deck is extremely recommended.
Maximize Your Card Duplication Chance
Here’s a very useful tips for when you want to focus on building a character: when doing a Chaos run, if you are focusing on building a single character and wants to duplicate their cards as much as possible, it is highly recommended that you use the card removal functions to remove the other characters’ cards in the party.
This is to ensure that the character you are building has the most cards and is more likely to get the Card Duplication event, as the cards chosen for Duplication are chosen at random.
Be Aware of Neutral, Forbidden And Monster Cards Value
The different Neutral, Forbidden and Monster Cards each have their own value, making some of the cards that can be added to the deck more valuable than most. Therefore, before adding them into your deck, players should weigh the effect of each of these cards carefully.
Generally speaking, Monster Cards are not worth putting into your deck as their values are too high, meaning they will be removed immediately the moment you exceed the maximum value.
For Neutral Cards, their value fluctuates greatly between characters due to some Neutral Cards’ effects being extremely strong, while others are generally not worth it. Players also need to consider the card’s value if you want to put Divine Epiphanies on these Neutral cards, since Divine epiphanies will skyrocket the points value of these cards and may result in demotion once you are out of the Chaos.
High Value Decks Do Not Equal Strong Decks
To cap off, it is important to remind players that just because a card deck is high in Save Value does not automatically make it a strong deck.

Every character in the game has different playstyles with different cards in their decks offering more value to their playstyles than others. Some characters in the game even want to have as few cards as possible in their deck to maximize their gameplay rotation, while others want to have multiple copies of very specific cards in their decks to perform their combo and don’t necessarily need to invest in other cards.
Therefore, even if your card deck is low in value, if it fits the character’s playstyle and you are comfortable with playing the deck, then that deck is a strong deck for you to use. Some decks can even be used from the start of the game all the way until the endgame just because of how optimized they are!
So don’t worry about the cards’ points value too much and focus on building the card decks that you are most comfortable with using!
