Can You Reroll?
Reroll Possible but Not Recommended
| Average Time to Reroll |
|---|
| Around 20 minutes |
| Number of Pulls per Reroll |
| 6 pulls + 23 pulls on the Standard Gacha |
While it's possible to reroll in CZN, we generally do not recommend it since each attempt takes a fairly long time.
Character Training is More Important
In CZN, a character's strength can vary greatly depending on the save data created through Chaos Manifestation. Even low-rarity characters can perform exceptionally well depending on the save data, so there's no need to force pulling for high-rarity characters.
Obtain 5-star Character in an Hour
In CZN, there is a beginner-exclusive Gacha where you are guaranteed to get a 5-star character after 50 pulls. Since you can get a 5-star character in about an hour of play, deciding after seeing the results is also an option.
200 Farmable Pulls
In CZN, you can pull from the gacha 200 times just by playing through the early stages. There is also a beginner gacha that guarantees a 5-star character after 50 pulls, so we recommend starting the game without worrying about your initial pulls.
Training is More Important Than Character Rarity
In CZN, the strength of the same character can change drastically depending on the Save Data created with Chaos Manifestation. Since even low-rarity characters can perform well depending on their Save Data, there is no need to force yourself to aim for high-rarity characters.
Rerolling Tier List
Best Characters for Rerolling
Sereniel Is the Best for Rerolling

As the first limited seasonal character with a unique ravage build and high Tenacity damage output, Sereniel easily earns SS-tier status this season, delivering unparalleled sustained damage and elite break performance in difficult content.
Sereniel Best Build and KitHaru Is a Strong Attacker

Haru is an Attacker who is featured as the first rescue banner character. She can deal high damage and will be a valuable Attacker for a long time.
Haru Rating and Recommended BuildMei Lin Is a Recommended Solid Attacker

Mei Lin is an easy-to-use attacker. With buffs that can be used at Initiation and card draw abilities, she is an ideal choice for players learning the game or looking for a dependable damage dealer.
Mei Lin BuildKhalipe Is Also a Good Choice

Khalipe is a Vanguard who excels at protecting allies with her Shield. In addition, she also has Attack Cards that are triggered by other Cards, and can be widely effective from the early game to high-difficulty content.
Khalipe BuildUnlockable Starter 4-Star Characters
Among the 4-star characters, the 5 mentioned above can be obtained from regular gameplay. Although Mika and Tressa have excellent performance for 4-star characters, we have given them a lower rating for rerolling purposes.
Best Banners for Rerolling
Combatant Rescue Rate Up

In the Combatant Rescue Rate Up banner, the drop rates for specific characters are increased, making it easier to get the character you want. We generally recommend rerolling on this banner.
Combatant Rescue Banners Are Not Time-Limited
In CZN, characters other than collaboration or seasonal limited ones will be added to the standard Combatant Rescue banner once their banner period ends. This means it's not absolutely necessary to get them during the banner period, so rerolling on the Combatant Rescue banner also becomes an option depending on the situation.
When to Stop Rerolling
Stop if You Pull an SS-Rank Character

If you decide to reroll, you should start playing through the game once you get one SS-rank character. In CZN, you only use 3 characters at a time, so having just one SS-rank character is enough to progress through the early game.
