How to reroll efficiently in Chaos Zero Nightmare
Rerolling in Chaos Zero Nightmare isn’t complicated, but it rewards patience, timing, and a little bit of luck. Think of it as your first real mission aboard the SS Nightmare, only this time, your enemy isn’t a horde of monsters but the cruel god of RNG.

The idea is simple: start fresh, test your luck on the early banners, and repeat until you snag a powerful combatant that makes your early loops smoother and more rewarding. Each reroll cycle typically takes between 15–25 minutes, depending on how quickly you skip dialogue and animations.
Once you get into the rhythm, it becomes a smooth loop, ideal for players who enjoy optimization as much as gameplay. With efficiency, you can easily get several reroll attempts in an hour, drastically increasing your chances of landing your dream combatant.
