Reroll

The short answer for NIKKE: reroll isn't strongly encouraged right now, which runs against the usual gacha instinct of "you need a perfect roster from day one." The reason comes down to the game's own design — NIKKE leans heavily idle-game, meaning a large share of progression (resources, EXP, upgrade materials) is designed to accumulate on its own over real time, rather than being fully gated behind landing an SSR pickup on your very first pulls.

Because that resource clock starts ticking the moment an account is created, every hour spent rerolling (wiping the account, starting over, pulling again) is an hour your main account isn't passively banking free resources. For most players, the more sensible approach is to start early on a single account, accept an imperfect opening roster, and focus on steadily stockpiling jewel for future pickup banners that matter — rather than burning early playtime on repeated restarts.

There's also a technical hurdle: guest accounts are blocked from rerolling, so starting fresh requires a new email for every attempt — a much higher time/effort cost per reroll than games that only need a local data wipe. Combined with an idle-heavy design that doesn't reward a perfect opening all that much, most players are better off skipping reroll entirely and putting that effort into long-term accumulation instead.

If you do decide to reroll, the most important principle is locking in the right goal before you start: it's not about hoarding as many SSRs as possible, it's about pulling until you land the one SSR pickup character carrying the current banner — the character you've already identified as the long-term core for the playstyle you're aiming for. A pile of random SSRs in mismatched roles won't help nearly as much as a single strong pickup to build around.

Rates worth knowing before you pull: SSR on a regular, non-pickup banner sits at 4%; the slice reserved specifically for the current pickup SSR is 2%; if that banner belongs to the Pilgrim manufacturer, the pickup rate drops further to 1%; the system also tracks a separate friendship rate of 2%. Since pickup odds aren't high, go into each reroll attempt expecting to spend the entire free pull allotment a new account gets before judging the result and deciding whether to keep that account or start over.

Because guest accounts are blocked from rerolling, every fresh attempt needs its own new email — so it's more time-efficient to line up several emails ahead of time and batch your attempts rather than doing one reroll at a time.

Beyond raw SSR/pickup luck, NIKKE has a fixed safety-net mechanic — the pity — built around Gold Mileage: every 10 pulls earns 10 Gold Mileage, and once you've banked 200 Gold Mileage, you can exchange it directly for the current banner's SSR pickup character — no more relying on luck at that point.

The key thing about that 200 Mileage threshold is that it never disappears when a banner ends — Mileage carries over across every banner you pull on. If you're short of 200 this month, next month's total simply picks up where you left off and keeps adding, until you eventually cross the line. In other words, even after a specific pickup banner has come and gone, whatever Mileage you've banked was never wasted.

For new players weighing whether to reroll, this is the real argument against rushing into it: since Mileage is a permanent, non-expiring safety net, a single account played consistently from early on — even with an unlucky opening and zero pickup SSRs — is guaranteed to hit that 200 Mileage mark sooner or later, instead of betting everything on a handful of lucky early pulls.
