  • Know what to upgrade next — Every stat ranked by the damage it adds — against your real opponent, because their defenses change everything.
  • Profiles you can share — Save your build and your opponents', share them as a link — one click adds them — and update them as your stats grow.

Frequently asked questions

Is it free? Do I need an account?

Yes, everything is free and there is no account. Open a page and start calculating.

Where is my data saved? Can I lose everything?

On your device, in your browser, after every change: when you come back, your last simulation is still there. Nothing is sent to a server. In a private window, or if you clear the site's data, everything is lost: save your profile and keep its 🔗 link (on Discord for example) to get it back anywhere.

How do I share my sheet with someone?

Save it as a profile (Profiles: give it a name, then Save Me), click its 🔗 Copy this profile's link and send the link. The other player just clicks it: your profile is added to their profiles, without touching their simulation. When your stats change, Update the profile and send the link again. To send a whole simulation (you, the opponent, weapon, skill, options): Copy link.

How do I move from my PC to my phone?

Nothing syncs on its own: send yourself your profile's 🔗 link (or Copy link for the whole simulation) and open it on your phone. For Smelting, Export / Import saves your prices to a file and loads it on the other device.

Are the results reliable? For which server?

The formulas are the EU server's, verified in-game: PvP damage lands exactly on the game's numbers, and so do the Haste, ASPD, Crit and PEN values the game shows. Enter your stats with their decimals (or import screenshots) for an exact result.

Can I install it and use it offline?

Yes, if your browser offers it (Chrome, Edge, Android): Install the app — the ⬇ icon at the top or the link at the bottom of the page — adds it to your phone or PC like an app. On iPhone: Share → Add to Home Screen. The calculators then work without a connection (screenshot import needs internet the first time).
