How every ER targetgets calculated.How every ER target | gets calculated.
No black box. Here's the exact math behind every ER target — from particle generation to team energy flow.
WHY ENERGY RECHARGE MATTERS
Energy Recharge determines how often you can cast your characters' Elemental Bursts. Too little ER and your rotation stalls. Too much and you sacrifice offensive stats. Finding the exact target is the key.
Burst Cost Ranges
Every character needs 40-90 energy to cast their Elemental Burst. Higher-cost bursts demand more Energy Recharge to maintain rotation uptime.
Team Synergy Matters
Same-element teammates generate particles you can catch at higher efficiency. Team composition directly shapes how much ER each character needs to function.
Rotation Dependent
Longer rotations mean more skill casts and more particles. The number of times you use each skill per rotation determines your total energy income.
HOW ER IS CALCULATED
The Math, Automated
Every particle, every energy conversion, every team interaction — calculated using the same formulas as KQM spreadsheets, but automated. No manual math. No spreadsheet errors.
Particle Energy
Elemental particles generated by skills, converted to energy based on element matching and field time.
Flat Energy
Energy from passive talents, constellation effects, weapon passives, and artifact set bonuses. Not multiplied by ER%.
Team Context
Elemental resonance, funneling between characters, and party size all affect how much energy each character receives.

WHAT AFFECTS YOUR ER NEEDS
Your Team Composition
The single biggest factor. Same-element teammates share particles more efficiently. A well-built team can reduce individual ER requirements by 20-40% compared to running mismatched elements.
Team composition can change your ER needs by up to 40%

Character Choice
Base burst cost, ascension stat, and personal energy generation define your baseline ER needs.
Weapon Selection
ER substat weapons like Favonius provide up to 55% ER. Weapon passives can also generate energy.
Artifact Sets & Stats
Emblem of Severed Fate 2pc gives +20% ER. Sands main stat and substats add significant ER%.
Constellations
Some constellations refund energy or generate extra particles at higher investment levels.

FREQUENTLY ASKED QUESTIONS
Quick answers about how ER works and how our calculator handles it.
Energy Recharge (ER%) is a stat that increases the amount of energy a character gains from picking up elemental particles and orbs. All characters start at 100% ER. Higher ER means more energy per particle, which means more frequent Elemental Bursts. The maximum practical ER is 300%.
Energy from particles is multiplied by your ER%. The higher your ER%, the more energy you get per particle. Flat energy from passives, constellations, and weapon effects is added AFTER the ER multiplier — it is not affected by ER%. The core relationship is: Total Energy = (Particle Energy × ER%) + Flat Energy.
Skills generate elemental particles. When you catch a particle, the energy you receive depends on element matching: same-element particles give the most energy, different-element give less, and neutral (clear) particles are in between. Characters who are off-field when particles arrive receive reduced energy compared to the active character.
Flat energy is energy that bypasses the ER% multiplier entirely. It comes from passive talents (Raiden A4), constellation effects (Sara C2, Faruzan C6), weapon passives (Favonius series), and artifact set bonuses (The Exile 4pc, Scholar 4pc). Flat energy is added directly to your energy total regardless of your ER%.
Team composition is the single biggest factor in ER requirements. Same-element teammates generate particles you can catch at full efficiency. A well-coordinated team with a battery character can reduce ER needs by 20-40%. Elemental resonance (Electro = more particles, Anemo = cooldown reduction) also plays a role.
ER QuickCalc uses deterministic simulation based on real game data from official sources and the community. Our engine accounts for all known energy mechanics including particle generation rates, element matching multipliers, flat energy sources, team resonance, and weapon effects. Accuracy depends on correct input — use realistic rotation timings and team configurations for the best results.
