As a Support, Kazuha’s best weapon inGenshin Impactshould be versatile like its wielder. Although he can take on many tasks, Kazuha’s build decides his role. The most important part of any build is choosing the right weapon.
As Kazuha depends on his Elemental Mastery (EM) to transport it to Elemental DMG%, having EM in a weapon can be crucial. So weapons like Iron Sting and Freedom-Sworn Sword are a great option. But other than these two obvious weapons, Kazuha can swing many other swords.

Updated on June 12, 2025, by Nahda Nabiilah:There’s no doubt that Kazuha is still one of the most useful units in Genshin Impact. With every version and every new DPS unit, Kazuha becomes more and more important as his buff is a universal damage buff that has very few limitations. Also, with every version, more new artifacts and weapons are released and could match some characters to improve their play style. For Kazuha, some new 4-star weapons slightly improve his Supporting abilities, so this list will be updated to include them.
8Festering Desire
Kazuha highly relies on hisElemental Skill and Burstto inflict DMG.Festering Desire’s secondary stat will help him maintain his Energy, while its passive will enhance Kazuha’s Skill. The only issue with this sword is that not everyone owns one since it was a free weapon given inGenshin Impact1.2.
7Primordial Jade Cutter
NoSword user inGenshin Impactperforms badly with Primordial Jade Cutter. This 5-star sword has everything a unit needs. From its decent Base ATK to its massive 44% Crit Rate Secondary Stats. Kazuha will definitely perform perfectly as a DPS when wielding Primordial Jade Cutter.
6Skyward Blade
Although Skyward Blade has Energy Recharge as Secondary Stats, it’s still considered in thehighest tiers ofGenshin Impact’s swordweapon tier list. The weapon’s Energy Recharge secondary helps Kazuha unleash more Elemental Bursts during combat.
5Sacrificial Sword
Sacrificial weapons are amazing forGenshin Impact’s Support characters, and Kazuha is one of them. Kazuha not only will be able to cast his Elemental Skill again and get more Elemental particles but he will also Crowd Control the enemies and Plunge attack them once again.
4Toukabou Shigure
Toukabou Shigure is a decent4-star option for Kazuha inGenshin Impact. From this weapon, Kazuha only needs the 165 Elemental Mastery, and everything else that comes after is just extra damage that he can’t make the most of.
3Iron Sting
Iron Sting is a great F2P choice for Kazuha. Adding 24% DMG to his abilities is already a great deal, and Iron Sting adds much more than that.The forgeableGenshin Impactweaponadds 165 Elemental Mastery, which will be transformed into even more Elemental DMG with Kazuha. With its high Base Stats, Iron Sting allows Kazuha to perform his Supportive tasks while inhabiting the Sub-DPS role.
2Xiphos' Moonlight
Xiphos' Moonlight is one of Kazuha’sbest swords inGenshin Impact. The weapon grants Kazuha all the Elemental Mastery he wants, in addition to some juicy Energy Recharge that scales with his Elemental Mastery. Moreover, Xiphos' Moonlight also takes a portion of that Energy Recharge buff and grants it to everyone in Kazuha’s team. Kazuha with Xiphos' Moonlight is a very Supportive unit that can do so much more than he is already capable of doing.
1Freedom-Sworn Sword
Given that Freedom-Sworn Sword is specifically made as Kazuha’s signature weapon, it’s no surprise it’s Kazuha’s best-in-slot (BiS) weapon inGenshin Impact. It pushes him further as a support by giving a high Elemental Mastery stat, and the weapon’s passive can provide a buff for the whole team if Kazuha meets the requirements. Unsurprisingly, it’s very easy for Kazuha to activate Freedom-Sworn’s effect, since he can trigger multiple Swirls immediately when using hisElemental Skill or Burst inGenshin Impact.
