@Sivin Is so the story banner normally isn't worth much since its only accessible to the servants you unlock through out the story, everyone talks about event banner so take that as a small recommendation to not roll on story banners

@Aorusdam well, i don't know if my thinking is good, but aren't there story exclusive servants that are only available on story banner? Like Bedivere or Caster Cu?

I've been throwing multis on the story banner here and there over the years, I only ever got 3* Story locked servants, but I did get a really good amount of SSR CEs (2 Kaleidos, 1 Black Grail, 2 2030 to name a few), so overall, it's a "do you feel lucky" banner when you want to roll and the current banners don't interest you lol

Do keep in mind the story banner has no rate ups, so it's pure RNG to get who you want

Mostly, no. Limited servants will never show up in the story banner, even when running in an event banner. Only the gen pool servants (who can spook you in any banner) and the story lock servants (who can't spook, and are only available through the story banner or rate up event banners).

If you want a story lock that isn't getting a rate up banner any time soon, you may have no choice but to roll the story banner, but the odds of a story lock, never mind the one you want, aren't any higher than the rest of the servant list there.

Nope. Either roll at normal banners with rate up or wait for class-based banner. Even then, most of the time, normal banners is better because they have rate up. As for story locked servants like Cu Caster or Salieri or Bedivere, you can get them from their banner or class-based banner.

Is there a list which banner will come when on NA?

IMO if you want a better chance at 5 star CEs; I have two fully limit broken BG and almost at my third Kscope. Not rolling story at all is the best way to never get CEs
