Understanding Kazuha’s Energy Requirements Fundamentals
Let’s be honest here—energy management is where most Kazuha builds fall apart. I’ve seen too many players either overcap ER at 280% (completely unnecessary) or run him at 140% thinking it’ll be fine only to watch their rotations crumble.
60 Energy Burst Cost Analysis
Kazuha’s 60-energy burst with that sweet 15-second cooldown? It’s actually perfectly designed for quickswap rotations—when you’ve got the energy to back it up. Miss that energy threshold and you’re looking at dead time that tanks your team DPS harder than you’d think.
The math here isn’t negotiable. Without proper ER, that beautiful crowd control and elemental damage bonus just… sits there. Waiting.

Base ER Without Support
Here’s where it gets interesting. Running Kazuha solo Anemo (which honestly, you shouldn’t do unless you absolutely have to):
Solo Anemo (1 Tap + 1 Hold Skill): 190-200% ER
Solo Anemo (2 Tap Skills): 205-215% ER
Solo Anemo (1 Hold Skill only): 270-280% ER
That last one? Don’t. Just don’t. I’ve tested it extensively and it’s artifact hell for minimal gain.
Energy Particle Mechanics
This is where the real optimization happens—and where most guides get weirdly technical without explaining why it matters.
Anemo Particles: 2.7 energy on-field, 2.4 off-field Non-Anemo Particles: 0.9 energy on-field, 0.8 off-field Clear Particles (Favonius): 1.8 energy on-field, 1.6 off-field
See that difference between on-field and off-field? That’s why funneling energy by keeping Kazuha active when particles drop is actually worth the extra second of field time. Small optimization, big impact over dozens of rotations.
Favonius Sword Impact on ER Requirements
Now we’re talking. Favonius Sword isn’t just decent—it’s a complete game-changer for Kazuha’s energy economy.
Energy Generation Calculations
The 61.3% ER substat alone is massive, but the real magic happens with those clear particles. Six energy to whoever picks them up, and in a well-coordinated team, that’s often going straight to your next burst rotation.
Here’s what actually happens to your ER requirements:
Solo Anemo: Drops from 190-200% to 160-170% (single proc)
With Raiden: Drops from 155-170% to 120-130%
Double proc scenarios: Another 10-20% reduction
That shift from ER Sands to EM Sands? That’s where Kazuha transforms from decent support to team damage amplifier.
Crit Rate Requirements
Let’s address the elephant in the room—yes, you need some crit rate. But not as much as you think.
With just 20% CRIT Rate at R1:
Single enemy: 47.2% proc chance per rotation
Two enemies: 72.1% proc chance per rotation
R5 with two enemies: 89.3% proc chance
(Editor’s note: I actually prefer targeting around 25-30% crit rate for that extra reliability, but 20% is the mathematical minimum for consistent procs.)
Proc Rate Analysis
Refinement scaling is where Favonius gets spicy:
R1: 60% chance, 12-second cooldown
R3: 80% chance, 9-second cooldown
R5: 100% chance, 6-second cooldown
R5 Favonius on Kazuha? That’s energy management on easy mode.
Raiden Shogun Synergy and Energy Restoration
This combo is honestly broken in the best possible way.
Energy Return Mechanics
Raiden’s energy restoration during her 7-second Musou Isshin state hits different with Kazuha. Five ticks of energy restoration, scaling with her ER through that A4 passive—a 250% ER Raiden provides 90% more energy than baseline.

Rotation Optimization
Here’s where theory meets practice. In Raiden teams, Kazuha’s ER requirements for single Hold Skill rotation drop from that painful 270-280% down to 155-170%. Add Favonius? We’re talking 120-130%.
That’s not just comfortable—that’s build pure EM and watch everything melt territory.
Team Composition Effects
What I love about Raiden battery support:
Predictable energy restoration (no RNG)
Consistent 60-cost burst uptime
Flexibility to build offensive stats
Smoother rotation timing
It just works.
ER Calculator and Calculation Methods
Step-by-Step Formula
Real ER calculations need to account for:
Base energy cost (60 for Kazuha)
Particle generation (3-4 per skill use)
Team particle contribution
Weapon passive effects
Rotation length and execution
The devil’s in those execution details—enemy positioning affects particle timing more than most players realize.
Team Scenarios
Triple Anemo Teams: 145-155% ER (multiple batteries make life easy) Freeze Teams: 170-190% ER (predictable but solo Anemo) Reaction Teams with Raiden: 120-150% ER (maximum EM investment potential)
Practical Examples
Standard Kazuha-Raiden sequence looks like:
Kazuha Hold Skill (4 particles, ~11 energy)
Team setup abilities
Raiden Burst (restores ~25-30 energy)
Kazuha Burst ready for next rotation
Clean. Efficient. Reliable.
Optimal ER Thresholds for Different Setups
Solo Kazuha Requirements
Conservative (2 Tap Skills): 205-215% ER—safe but requires ER Sands Balanced (1 Tap + 1 Hold): 190-200% ER—most common and practical Aggressive (Hold focus): 270-280% ER—artifact nightmare, avoid
Favonius Users Impact
Each additional Favonius weapon in your team reduces Kazuha’s ER needs by roughly 10-15%. Stack them up: Single Favonius (Kazuha): 160-170% target Multiple Favonius: 140-160% target
More Favonius weapons = more artifact flexibility. Simple math.
Raiden Team Optimization
Raiden + Favonius Kazuha: 120-130% ER (maximum EM investment) Raiden + Iron Sting Kazuha: 155-170% ER (needs better substats)
Weapon Comparison for Energy Generation
Favonius vs Iron Sting
This debate comes up constantly, so let me settle it:
Favonius Sword: 61.3% ER substat, team-wide energy support, enables EM Sands, works in any team comp Iron Sting: 165 EM for bigger buffs and Swirl damage, higher damage ceiling, craftable
Here’s the thing—Favonius with EM Sands often gives you better total stats than Iron Sting with ER Sands. The weapon choice makes the artifact choice, not the other way around.
Freedom-Sworn Considerations
608 EM at Level 90 is gorgeous, but zero ER support means you need 150-200% ER from artifacts alone. Only worth it if you’ve got god-tier artifacts and strong team energy support.
Basically, it’s the I have perfect artifacts weapon.
F2P Options Analysis
Fleuve Cendre Ferryman: 45.9% ER at R5, plus that 32% ER boost after Skill use Sacrificial Sword: Skill reset for double particles (needs R3+ for reliability) Amenoma Kageuchi: Energy restoration through stacks, craftable
All solid options, though none quite match Favonius for pure energy management.
Artifact Optimization and Substat Priority
ER vs EM Trade-offs
Priority hierarchy that actually works:
Meet ER threshold (whatever your team comp demands)
Maximize Elemental Mastery
CRIT Rate (Favonius users only)
ATK% (honestly, don’t worry about it)
Substat Value Calculations
ER Substats: Highest priority until you hit threshold, then worthless EM Substats: Direct scaling with A4 passive and Swirl damage CRIT Rate: Target 20-30% for Favonius reliability
Artifact Set Recommendations
4-piece Viridescent Venerer: The standard. 40% resistance shred is massive.
2VV + 2EM Sets: Extra 80 EM, but you lose that resistance shred 4-piece Emblem: Niche for Triple Anemo setups
VV is almost always correct unless you’re doing something very specific.
Common ER Requirement Misconceptions
Overcapping ER Issues
I see this constantly—players running 250%+ ER when 160-180% would work fine. You’re sacrificing EM and team damage for energy you don’t need.
The confusion usually comes from reading solo Anemo guides (180-220% ER) and applying those numbers to optimized teams (120-170% ER). Context matters.
Team Energy Myths
Energy management is a team sport. Multiple Favonius weapons, battery characters, proper rotation timing—it all works together. Building one character with excessive ER to solve energy problems? That’s inefficient resource allocation.
Rotation Mistakes
Common errors I see:
Switching off Kazuha before particles reach him
Poor funneling technique
Inconsistent skill patterns
Using burst regardless of energy state
Small mistakes, big impact on energy economy.
Advanced Team Composition Strategies
National Team Variants
In Raiden National, Kazuha replacing Sucrose brings enhanced personal damage, DMG% buffs instead of EM sharing, better grouping, and those flexible energy requirements we’ve been talking about.
The energy synergy lets you build full EM while maintaining burst uptime. It’s beautiful.
Freeze Team Optimization
Freeze teams are actually pretty forgiving for ER—170-190% usually works because rotations are predictable and positioning is consistent. You get balanced ER/EM distribution and reliable particle timing.
Hypercarry Support Builds
Pure support roles prioritize burst uptime for that A4 passive buff:
Conservative ER thresholds (180-200%)
Favonius preference for reliability
EM maximization after ER needs are met
FAQ
How much ER does Kazuha need without Raiden Shogun? 180-220% ER as sole Anemo character. For balanced rotations (1 Tap + 1 Hold), aim for 190-200%. Conservative approaches with 2 Tap Skills need 205-215%.
Does Favonius Sword significantly reduce Kazuha’s ER requirements? Absolutely. Reduces requirements by 30-40% through that 61.3% ER substat plus particle generation. Solo Anemo drops from 190-200% to 160-170%, which enables EM Sands usage.
What is Kazuha’s optimal ER with Raiden Shogun in the team? 155-170% for basic rotations. Combined with Favonius Sword, you’re looking at 120-130%—maximum EM investment territory.
How much CRIT Rate does Kazuha need for reliable Favonius Sword procs? 20% CRIT Rate gives you 47.2% proc chance against single enemies, 72.1% against two enemies at R1. R5 refinement hits 89.3% against two enemies.
Should I use ER Sands or EM Sands on Kazuha? EM Sands whenever possible for enhanced buffing and Swirl damage. Only use ER Sands if your weapon and substats can’t meet requirements. Generally, ER weapon + EM Sands beats EM weapon + ER Sands.
How do Kazuha’s constellations affect his ER requirements? C1 provides an extra Skill cast generating additional particles—lowers ER needs by 10-15%. C4 restores 3-4 energy when using Skills below 45 energy. Nice optimizations, but don’t build your energy management around constellations unless you have them.
