So far there are two ideal ways to build the Inazuma Samurai in Genshin Impact: As a support or a sub DPS. Going as a sub DPS might compromise the purity of teams, but it shines the best against single targets.
Normally when we think about support characters, leveling up is not priority. Nonetheless, with swirl being a transformative reaction Kazuha gets at level 90 (or as high if you have resources), it's worth the work.
On paper, Kazuha looks quite straight forward, increase elemental mastery and look for energy charge as secondary. Every Kazuha user should build a combination of 4 pieces of Viridescent Venerer.
However very few players have in their arsenal a full set of these green artifacts with Elemental Mastery (EM) as primary stats, which means that getting the ideal combination might take a long time. A more realistic set of artifacts can be a combination of 2 wanderer's troupe and 2 Viridescent for the extra 80 of elemental mastery.
- Priority Elemental Mastery
- Sand (Elemental Mastery / Atk%)
- Goblet (Elemental Mastery / Anemo Dmg)
- Circlet (Elemental Mastery / Crit Rate)
- For sub stats EM, Energy Recharge, Crit Rate, Crit DMG
Artifacts Sub DPS
For this, gather 2 set of gladiator and Viridiscent Venerer with priority for Crit Rate and Crit Damage. Having attack and Energy Recharge are priorities for secondaries.
The name of the game is damage, and Kazuha can certainly deal it!
It is important to pay attention to elemental skill. It can be used both ways: Press and hold with different cooldowns.
The big difference is that hold will expand the area of AOE so is better to regroup enemies. While pressing shorter CD will allow you to use it a second time in the same combo.
The priority to level up the talents is Burst first / Elemental Skill 2 / Normal Attack.
The most available and most obvious weapon would be Iron Sting, while Sacrificial Sword can be another F2P option. If you are planning to pull some weapon banners, they can be Freedom Sworn or Jade Cutter.
He is not the ultimate plug and play character, like Venti or Zhong Li but with the buff for Anemo Heroes, the buff in elemental damage that his passive gives to teammates, you can find Kazuha getting the job done with most team compositions.
Bennet, as with many other heroes, is his best ally. Rosaria can also be a great combination, making the current banner one that no one should miss.
In the first experiments tested with National Team, Morgana and basically any Vaporize and Melt team give a spectacular show with the absorption of pyro and cryo dmg.
Kazuha without constellations is a very useful character. For the support route 1 and 2 will make him a beast. If you are going for the Sub DPS the constellation 6 will increase his damage leveling up with the biggest damage dealers in the Genshin Impact.
