Kaedehara Kazuha build recommendations
Artifact stats priority
- crit rate, crit dmg
For an EM-focused build, upgrading Kazuha's talent levels isn't a necessity.
Note that upgrading Kazuha's NA talent increases the damage of his plunge attacks.
The element which is absorbed by Kazuha's elemental burst follows the priority of Pyro > Hydro > Electro > Cryo, and can be absorbed from both the active character and enemies. (i.e. Standing in Bennett 's Elemental Burst will result in Kazuha's Elemental Burst infusing Pyro as Bennett's Elemental Burst applies Pyro to the active character)
Recommended ER Thresholds
With Raiden: ~160 ER%
General Teams: ~180 ER%
Melt Ganyu: ~200 ER%
Kazuha's 4th Ascension Passive encourages players to maximise Elemental Mastery in order to maximise his utility.
Similar to Venti, due to the EM buffs, a triple EM build will out-damage a regular ATK-EM/Anemo/Crit build as long as there are 2+ enemies due to the amount of swirls involved. Because of this, an ADC (Attack/Damage/Crit) build isn't recommended unless he is in a team whereby he cannot make use of his A4 passive or swirls. (i.e. mono Anemo/Geo teams)
Regarding Weapon Choices
The ultimate goal is to try stack as much EM while getting enough ER for a consistent Burst uptime. Having Sacrificial Sword or a second Anemo character in the team will also help reduce the needs for ER and prioritize EM substats more.
With this weapon, try to aim for some Crit Rate stats to trigger the weapon passive reliably.
In teams where you can meet energy requirements without needing the extra particles from Favonius Sword this is a better choice with stronger personal damage and buffing. Also at high refinements (R4-R5) it starts beating Favonius Sword in team energy generation too.
Iron Sting will yield the highest upfront EM and teamwide buff if compared to the other 4 star options, if you manage to meet his energy needs or simply don't need more than one rotation, this would be the better option if compared to the Energy Recharge weapons.
This weapon performs very similarly to Iron Sting in a Swirl focused build even at higher refinements since its passive does not effect Swirl damage.
At R5, Amenoma Kageuchi needs no extra ER, and can focus building entirely EM. This makes it roughly equal to Iron Sting. At R1, Amenoma Kageuchi needs 138% Energy Recharge to burst consistently.
Only really viable at high refinement in specific dendro teams where you can trigger dendro reactions usually through swirling Electro/Hydro on enemies with dendro applied to them (most consistently done in aggravate reaction comps).
Regarding Artifact Sets
This is a niche build that excels only in AOE situations and with specific teams. Those teams include an off-field Hydro and Electro support to allow Kazuha to constantly trigger the 4p effect and spam his Elemental Skill, aswell as another Anemo support to hold the Viridiscent Venerer (4) set. Such teams can be Kazuha + Kokomi + Fischl + Venti, with Barbara and Sucrose being weaker replacements for Kokomi and Venti. This team triggers multiple fall damage instances against enemies that can be Crowd Controlled by Kazuha. Fischl can use The Viridiscent Hunt bow to allow for more fall damage instances. **NOTE: This team performs very poorly in pure single target situations
