Fan-made, unofficial
This is an independent fan-made tool. It is not affiliated with, endorsed by or sponsored by HoYoverse (COGNOSPHERE), Kuro Games or any other game publisher. Genshin Impact, Honkai: Star Rail, Zenless Zone Zero, Wuthering Waves and all related names are trademarks of their respective owners. No official game art or logos are used.
Estimates only
Calculations run in your browser using published banner rates plus community-measured soft pity. Games can change their rules at any time, and some values are estimates (they are marked). Results are provided "as is", without any warranty of accuracy, and you should not rely on them for any decision.
No gambling or spending advice
Nothing on this site is financial, gambling or spending advice, and it does not encourage you to buy in-game currency. Gacha pulls are random. Decide on a budget you are comfortable losing, never spend money you need, and take a break if pulling stops being fun. If spending on games is causing you problems, consider talking to someone you trust or a local support service.
Use of the site
You may use the calculator freely for personal purposes. Please do not scrape the site at high volume or try to disrupt it.
Liability
To the fullest extent permitted by law, ZDToolx is not liable for any loss arising from your use of this site.
