Chaos Zero Nightmare

Reroll guide

Treat the squad as a shared deck. Check draw, discard and retained cards before spending action resources; plan Ego skills and partner support around the cards you can actually play.

Your first objective

A reroll tries a different starting roster on a separate supported game profile. Decide what would justify restarting before you spend time doing it. A new character is useful when it fills a role you can support; rarity alone does not tell you whether the account will progress more smoothly.

A practical sequence

Check the game’s official account and server options first. Complete the normal opening until the summon menu becomes available, claim only currently eligible rewards, and inspect the banner’s pool and guarantee details. Compare the result with the relevant mode in the tier list. Keep a useful profile and record its login method and server before attempting another start.

Before spending resources

There is no universal number of free summons or fixed reroll time across these games. Rewards can expire, guest-account rules differ and permanent and limited banners may use different counters. Do not assume that reinstalling resets server progress. Before restarting again, try the acquired character and compare the missing support or gear with the requirements shown in its build.
