FGO got a pity.
In a spark, you get select the SSR from the shop or menu like in Blue Archive or GBF.
See pìc related.
In a pity, like in FGO, you roll until the gacha is literally forced to make the SSR appear in your rolls.
In FGO you roll in the banner, and if you didn't get the SSR after rolling 900 quartz, the gacha will forcefully make it appear in the last gacha roll.
It's a pity.
