Understanding banner math

Soft pity is not a separate pool—it increases the per-pull success rate. Hard pity is a ceiling that guarantees a drop on that pull if you have not hit yet.

Are these rates official?

No. Presets mirror community-documented structures but you should edit fields to match live banners. This site is not affiliated with any publisher.

How is soft pity modeled?

From the soft pity pull onward, we add a linear increment to the base rate each pull until hard pity forces a 100% rate.
