Model contract
Methodology and sources
PityLab computes a probability distribution with dynamic programming. It does not simulate random pulls, predict your account, connect to a game client, or guarantee an outcome.
What the engine calculates
For each pull, the engine advances the selected banner's pity state, applies the disclosed top-rarity rate, then applies the featured-target rule. A non-featured top-rarity result resets pity and advances the guarantee state. Multiple-copy results convolve the one-copy distributions. The number shown is exact only for this documented model.
Source hierarchy
| Game | Hard rules | Soft-pity treatment |
|---|---|---|
| Genshin Impact | Current in-game Wish Details; official site | Disclosed linear community approximation; Capturing Radiance is not modelled. |
| Honkai: Star Rail | Current in-game Warp Details; official site | Disclosed linear community approximation. |
| Zenless Zone Zero | Current in-game Signal Search Details; official site | Disclosed linear community approximation. |
| Wuthering Waves | Current in-game Convene Info; official site | Disclosed linear community approximation. |
| Neverness to Everness | Official Limited Board rules: Modified after 70 failures, featured guaranteed on roll 90, shared progress. | 0.99% Baseline and 19.59% Modified rates from the published board details; 1.87% is the consolidated rate, not the pre-pity base rate. |
Known limits
- Publishers can change rates, guarantees, banner pools and carry-over rules. Check the in-game Details screen before spending currency.
- Community soft-pity approximations are not publisher-certified per-pull tables.
- Bonus systems, special tiles, rebates, free pulls, currency prices and account-specific history beyond the entered pity/guarantee state are excluded.
- The Azur Promilia beta sandbox is preserved at its old URL but is noindex and absent from navigation/sitemap because no current official rate table was verified.
Update and correction policy
Rules were reviewed on 22 July 2026. Publisher or in-game rules override this site. If a rule cannot be verified, the affected page is excluded from search rather than silently presented as current.
