Hi, I'm Qeven
I play Genshin Impact (UID 611029827) and I got tired of spreadsheet math. ER QuickCalc is my answer to a problem every endgame player hits: how much Energy Recharge does this character actually need in my team?
Why I Built This
Energy Recharge is the most misunderstood stat in Genshin. Community guides quote ranges — 180% here, 220% there — but the real number depends on your exact team, weapons, constellations, and rotation. I built ER QuickCalc to simulate the full particle economy of a team: every skill cast, every catch, every Favonius proc, every constellation refund. The tool answers the question guides can't.
How the Data Is Maintained
The calculator's engine database stores each character's burst cost, skill cooldowns, and particle output. Values are verified against in-game behavior and community theorycrafting sources, then cross-checked when new versions ship. When data changes — balance patches, new characters, kit corrections — the engine is updated and every affected guide is reviewed.
What I Believe About This Project
- Free forever. No paywalls, no account required, no ads on the calculator itself.
- Transparent math. Every guide shows its working — if a number looks wrong, the formula is printed right above it.
- Fan-made, not affiliated. This is a labor of love for the game, built by a player for players.
