# Rate-up

> The boosted probability given to featured items on a banner. A rate-up rarely changes the overall top-rarity rate; it redirects a share of it toward the featured character, such as 0.7% of Fate/Grand Order's 1%.

A rate-up is the boosted probability a [banner](/wiki/banner) assigns to its featured items. The detail that matters, and that players routinely misread: a rate-up almost never raises the overall top-rarity rate. It reallocates a slice of the existing rate to the featured item.

Examples from published disclosures: in [Fate/Grand Order](/wiki/fate-grand-order), the SSR rate stays 1% on a rate-up banner, with roughly 0.7 points of it assigned to the featured servant. [[1]](#ref-1) In [NIKKE](/wiki/nikke), the SSR rate stays 4%, with 2 points on the featured unit. [[2]](#ref-2) Pulling on a rate-up banner therefore changes what you are likely to get, not how often you get something good.

HoYoverse games implement rate-up differently, through the [50/50](/wiki/fifty-fifty): each top-rarity result flips between the featured character and the standard pool, with loss protection. The effect is a featured share of 50% or better per 5-star, far above the fractional rate-ups of older designs, which is part of why the 50/50 pattern spread.

"Off-rate" or "spook" describes the complement: pulling a top-rarity item that is not the featured one. In games without loss protection, a spook can consume a long streak of luck without advancing the player's actual goal, which is the main argument players make for [spark](/wiki/spark) ceilings.
