About These Calculators
Archero 2's progression systems tangle stats, materials, and probabilities in ways that are hard to verify in-game. This calculator collection helps you compute the resources and expected outcomes before you commit to a growth target.
The stat calculator simulates final stats with gear, runes, research, and guild effects factored in. The arrow ability calculator visualizes how arrow-related numbers shift, and the summon calculator predicts Aeon Core pity and pull costs.

The character shard calculator estimates how many shards and how much real time you need to reach a target tier, and the rune calculators lay out enhancement and combination costs. Run the relevant calculator before any major investment.
These calculators are built from direct in-game testing and verification, but some numbers may differ slightly from what the game shows (rounding, application order, etc.). For major decisions, double-check directly against the in-game display.
A typical workflow is target → required resources → estimated schedule. For example, use the character shard calculator to estimate how many days it takes to push a target character to the next resonance star (3★ or 6★) or to 8★, then cross-check your gem priorities against the gem-spending guide for that window.
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.
