Which calculator to use when
Before spending on gear or artifacts, use the damage efficiency calculator to see whether ATK%, crit or boss damage raises damage most. It follows the add/multiply structure verified in the damage test.
The hero shard calculator estimates time to a target star from your chosen sources; the Aeon Core and Vibrant Voyage calculators show pulls and cost by luck before an event starts.
Frequently Asked Questions
QCan the calculator results differ from the in-game numbers?
Some values can shift after a patch. Each calculator is verified against the latest patch as it is maintained, but for major decisions we still recommend comparing directly against the in-game display.
QWhich calculator should I start with?
Start with the calculator that matches the system you are currently investing the most resources into. If you are focused on character growth, the character shard calculator; if power level is the goal, the stat calculator first.
QCan I use the calculators on mobile?
Yes. Every calculator is optimized for mobile screens, so you can check numbers while playing the game.
QAre my inputs saved automatically?
Most calculators store your inputs in the browser so they persist when you reopen the page on the same device. Inputs do not transfer between devices and may not save in private/incognito windows.
QWhat data do the calculators run on?
They are built on data verified through direct in-game testing. Base stats for characters, gear, and runes, enhancement and fusion costs, summon probabilities — all use the values shown in-game, and we re-verify and update after patches.
