Kazuha Build Guide
- Kazuha is one of the most versatile supports in Genshin Impact, providing enemy grouping, Elemental RES shred via 4-pc Viridescent Venerer, and team-wide Elemental DMG bonus based on his Elemental Mastery.
- Build him with triple EM main stats (Sands, Goblet, Circlet) — the more EM, the more Elemental DMG bonus he shares with the team.
- His best artifact set is Viridescent Venerer (4-pc) — no other set competes for Anemo support roles.
- Energy Recharge is critical: aim for 160%+ ER to ensure his Burst is available every rotation. Favonius Sword helps meet ER needs while supporting the team.
Best Weapons for Kazuha
| Weapon | Rarity | Main Stat | Notes |
|---|---|---|---|
| Freedom-Sworn | 5★ | Elemental Mastery | Signature weapon. High EM, team-wide ATK and DMG buffs. Best-in-slot for damage amplification. |
| Xiphos' Moonlight | 4★ | Elemental Mastery | Excellent EM stat stick that also provides ER to Kazuha and the team based on his EM. Perfect synergy with his build. |
| Iron Sting | 4★ | Elemental Mastery | Craftable F2P option. Provides 165 EM at level 90. The passive is largely irrelevant but the EM stat alone makes it strong. |
| Favonius Sword | 4★ | Energy Recharge | Best utility option. Generates energy particles for the entire team. Sacrifices some personal EM for dramatically better team energy economy. Highly recommended for energy-hungry teams. |
Best Artifacts for Kazuha
| Artifact Set | Piece Combination | Notes |
|---|---|---|
| Viridescent Venerer | 4-pc | Uncontested BiS. 40% Elemental RES shred on Swirled elements plus 60% Swirl DMG bonus. No other set should be considered for support Kazuha. |
Best Team Comps
International Team (Childe Vaporize)
Childe / Kazuha / Xiangling / Bennett — Kazuha groups enemies, shreds Hydro and Pyro RES, and buffs both elements with his A4 passive via double Swirl setups. Bennett provides ATK and enables Kazuha to absorb Pyro. One of the most iconic teams in the game.
Freeze Team (Ayaka)
Ayaka / Shenhe / Kazuha / Kokomi — Kazuha groups frozen enemies and provides Cryo DMG bonus. Shenhe buffs Ayaka's Cryo damage further. Kokomi provides consistent Hydro application and healing. Extremely effective against freezable enemies.
Mono Element Teams
Kazuha excels in any team that relies on a single Elemental damage type (Pyro, Cryo, Hydro, Electro). Pair him with a main DPS, an off-field applicator of the same element, a flex buffer/healer, and watch the damage multiply.
Talent Priority
Elemental Burst > Elemental Skill > Normal Attack
For full-EM support Kazuha, talent levels provide minimal damage increase because Swirl damage scales only on character level and EM. However, his Burst has the highest raw multipliers. Level Normal Attack last (or leave at level 1) unless you are using Kazuha as an on-field DPS at C6.
Recommended Stats
| Artifact Slot | Main Stat | Substat Priority |
|---|---|---|
| Sands | Elemental Mastery | ER, EM, ATK% |
| Goblet | Elemental Mastery | ER, EM, ATK% |
| Circlet | Elemental Mastery | ER, EM, ATK% |
Target stats: 800-1,000 Elemental Mastery is the ideal range. 160%+ Energy Recharge ensures smooth rotations (higher without Favonius or Xiphos). EM main stats on all three pieces is mandatory for optimal team buffing — crit builds are only viable at C6 or for a sub-DPS playstyle.
Frequently Asked Questions
Q: Iron Sting or Favonius Sword — which should I use?
Use Iron Sting if your team has low energy requirements and you want to maximize Kazuha's personal EM for stronger buffs. Use Favonius Sword if your team is energy-hungry (e.g., Xiangling, Beidou, Eula teams) — the team-wide energy generation often outweighs the EM loss. When in doubt, Favonius is the safer, more comfortable choice.
Q: Should I build EM or Crit on Kazuha?
For C0-C5 support Kazuha, always build full EM. His A4 passive converts EM into team-wide Elemental DMG bonus, and Swirl damage scales purely on EM and character level. Crit builds are only competitive at C6, where his Normal/Charged/Plunging attacks gain Anemo infusion.
Q: Is Kazuha's C2 worth it?
Kazuha's C2 is one of the strongest early constellations in the game. It grants 200 EM to Kazuha and the active character within his Burst, which translates to 8% additional Elemental DMG bonus for the team. If you use Kazuha in reaction-based teams, C2 is a very high-value investment.
Q: Is triple EM mandatory on artifacts?
For optimal team support, yes. The difference between an EM/EM/EM build and an EM/Anemo/Crit build is significant — you lose Swirl damage and team buffing potential. EM main stat pieces are rare (especially goblet and circlet), but you should prioritize farming them. Even with mediocre substats, EM main stats are better than perfect non-EM pieces.
Q: What is the best 4-star sword for Kazuha?
Xiphos' Moonlight is the best 4-star sword, providing both EM and team-wide ER. Iron Sting is the best craftable option with 165 EM. Favonius Sword is the best utility option for energy-hungry teams. Toukabo Shigure (event weapon) is also decent. Choose based on your team's needs.
