Dark Iron Sword – Three-Star

This tool is a little different from the others, but it’s pretty simple as long as Liyue is unlocked. Just go to Liyue and find Chen the Sharp, a food seller. Talk to him.

You can only get this tool this way. Based on its level, it gives Kazuha 31 to 141 extra points of Elemental Mastery.

When he starts any kind of Electro-related response, even Swirl, its passive skill gives him a 20% boost to his ATK for 12 seconds. This works really well for Kazuha if you have players on your team who are always making Electro.

Also, this is a great low-cost tool for giving Kazuha some DPS ability while still meeting his EM needs.

Sacrificial Sword – Four-Star

Giving Kazuha the Sacrificial Sword is pretty much the same as letting him use his first sign, but the weapon isn’t as dependable. When Kazuha uses his Elemental Skill, there’s a 40–80% chance that the delay on that Skill will end right away thanks to its passive.

His Skill does a lot of Swirl damage, so this helps him out a lot. It’s not a big deal to use it twice in a row.

That, along with the sword’s 13.3 to 61.3 percent boost to Energy Recharge, makes him a beast in both Skill and Burst possible. Which is always a good thing, because it means you can focus on getting his EM up with spells.

Favonius Sword – Four-Star

The Favonius Sword and the Sacrificial Sword are very much the same. They both have the same base ATK, secondary stat, and even secondary stat %. But the most important difference is in how inactive they are.

Depending on how well it is refined, Kazuha has a 60% to 100% chance of making six Energy particles every 12 to 6 seconds with the Favonius Sword.

Having a high CRIT Rate on Kazuha is a plus because he will be making energy on top of the energy recharge he gets from the weapon, which means he will be able to do even more bursts. But it can be hard to find the right balance between CRIT Rate and EM.

That is, unless you want Kazuha to be a more powerful DPS. In that case, this sword is better than the holy sword for him.

Iron Sting – Four-Star

The Iron Sting is easy to get because you can make it at the blacksmith’s shop. Thank goodness for the break; it’s one of the best four-star options for Kazuha if you don’t want to spend any wishes.

This is because, based on its level, it gives him an extra 36 to 165 EM points.

Plus, because it’s passive, every time he deals Elemental DMG, it will boost all of his damage by 6–12% for six seconds, based on how refined it is. This can be used twice in a row and once every second.

Since Kazuha is all about Elemental DMG, this will always do good damage for him. At level 90, the base ATK of 510 is also pretty good.

Xiphos’ Moonlight – Four-Star

This tool is great for Kazuha because it gives EM to characters. It raises his EM by 36 to 165 points and gives him 0.036 to 0.072 percent Energy Recharge every ten seconds for every point of EM he has.

This buff also helps the rest of his team by 30%, so he’s not the only one who benefits.

This covers two important points for Kazuha: EM and ER. It also lets him help other party members by being a battery. Xiphos’ Moonlight is a good choice for support-based Kazuha because he doesn’t even have to be on the field for the passive effect to work.

Alley Flash – Four-Star

If you got lucky with the weapon gacha, the Alley Flash will work for Kazuha, but it’s better for making him a DPS. It only gives him 12 to 55 extra Elemental Mastery points, not as many as a sword like the Iron Sting.

Its base ATK, on the other hand, is a huge 620, and its passive skill raises all of his damage by 12 to 24 percent.

The bad thing is that taking damage stops this affect for five seconds. However, if you have a good shielder on your team, like Zhongli, that won’t matter as much. This weapon works well if you want to use Kazuha as a DPS on the field instead of a support unit.

Skyward Blade – Five-Star

Because it’s in every sign, Skyward Blade is one of the easiest five-star guns to get. It raises Kazuha’s base ATK by 46 to 608 points, based on his level.

Plus, every 12 to 55.1%, his Energy Recharge goes up, which helps him stay busy in fight.

Its passive voice does many things at once. When he does an Elemental Burst, which he does a lot because it gives him extra energy, it raises his CRIT Rate by 4 to 8 percent just by having it on. It also raises his Movement SPD and ATK SPD by 10 percent.

Hits that aren’t charged also do 20 to 40 percent of his ATK in Space Bar Clicker. It’s another good choice if you want Kazuha to be your main or secondary DPS.

Freedom-Sworn – Five-Star

If you really care about Kazuha, you should try Freedom-Sworn, which is his signature weapon. It gives him 43 to 198 extra EM points, which is almost 200 points just for getting it to level 90.

Depending on how refined it is, its passive also raises his DMG by 10 to 20%. A Sigil of Rebellion will also be made by setting off a natural reaction.

The team’s ATK will go up by 20 to 40 percent if they have two of these Sigils. Their Normal, Charged, and Plunged DMG will also go up by 16 to 32 percent. It’s a great choice if you want to use Kazuha as an assist and watch him destroy enemies with EM.
