Best Characters for Rerolling
Mei 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 BuildVeronica Can Provide Draw Support

Veronica can deal damage herself while also supporting allies with Draw Cards. She is widely effective as a sub-Attacker.

CZN 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.
Featured Units Are Not Time-Limited
In CZN, non-collaboration and non-seasonal characters are added to the standard banner after their event ends, so pulling during their featured period isn’t strictly necessary.
When to Stop Rerolling in CZN
Stop if You Pull an SS-Rank Character
If you’re rerolling, you can finish once you obtain one SS character. Since Chaos Zero only requires a team of three characters, having just one SS unit is enough to progress smoothly through the early stages.
