Quick Links
From the start ofGenshin Impact, the developers have been alternating between giving a free four-star character or weapon in each update. However, the Version 5.0 update was one of the few where you get both, withKachinabeing the free four-star unit acquired simply by continuing the story.
Kachinauses the Geo visionwith a Polearm as her weapon, and she can be used both on and off-field depending on your play style. However, you’ll need some specific gear based on the style you decide to go for.

Best Weapons For Kachina
While building any character including Kachina, choosing the right weapon is an important decision since itgives your character a bunch of much-needed buffs and stat bonuses. Here are the best choices you have for her:
Footprint of the Rainbow

Four Star Craftable
Released alongside Kachina in Natlan, this weapon’s blueprint can be bought from the region’s Blacksmith. Once acquired,it can increase her DEF massively, especially after you use her Elemental Skill.
Due to the lack of DEF-based weapons, this is currently the best in slot for both on-field and off-field Kachina, though youmight struggle with her Crit Ratio when used off-fieldwith this weapon.

Deathmatch
Four Star Battle Pass
This weapon can be decent for on-field Kachina if you’re going to fight over two enemies at a time. However, sinceit also gives Crit Rate just like her BIS artifact set, you’ll need a lot more Crit DMG on stats.
The Catch
Limited Five Star
Finally, if you want to focus on Kachina’s Elemental Burst while using her off-field, this weapon can be decentsince it gives her a ton of Energy Recharge.
Best Artifacts For Kachina
Depending on the play style you’re going for, Kachinamainly has two good artifact sets with a third decent alternative. Once you decide the set you want to use, you can choose the weapons from above based on it:
Scroll of the Hero of Cinder City
Off-field
This serves as the best in slot set for Kachina if you use her off-field, which isarguably the better play style for the kind of damage she puts out. Firstly, it commonly allows you to gain extra Energy.
Moreover, after triggering a reaction while your Skill is active, you can increase the Elemental DMG forall characters with the elements involved in that reaction.

Obsidian Codex
On-field
On the other hand, you’d want to use this set if you plan on using Kachina on the field. It gives herextra damage in Nightsoul’s Blessing statewhile also giving her a massive Crit Rate boost.
Husk of Opulent Dreams
Finally, if you don’t have the above set ready, you can use this one toget some extra DEF and Geo DMG Bonuson Kachina while using her on-field.
Kachina Artifact Stat Priority
Regardless of the build you use, the stats you’ll be looking for in your artifacts will roughly remain the same:
Crit Rate/DMG
Crit DMG/Rate > DEF Percent > Energy Recharge
Apart from the above stats, you can alsolook for some Elemental Masteryto increase theeffect of shields made from Kachina’s Crystallize reaction.
Kachina Talent Priority
Kachina can be a fairly simple character to understand in Genshin Impact since most of her damage comes from her Elemental Skill,whether it stays on the field by itself or with Kachina riding it. This makes the ability the first priority when it comes to upgrading her talents, and you’re able to completely focus on it.
Once the skill is done, you can upgrade Kachina’s Burst to get some extra damage and ignore her Normal Attack. In an ideal situation,you’ll never use these attacks, so upgrading them is a bit useless.
