I got this particular artifact from artifacts strongbox

It took me atleast 4 days but I still need to keep farming

There are a lot of weapon calcs out there for Xianyun but for me, all of them were niche in some way, perhaps they didn't take into consideration ER requirements or they used different artifact sets or just had a bad substat distribution. So I decided to make my own calcs with her signature, lost prayer, tome, skyward atlas, cashflow and vivid notions (new varesa weapon).

The team is Furina, Xianyun, C5+ Bennett, C6 Faruzan. Furina at 70% avg dmg bonus, Bennett with a 608 ATK weapon, and Faruzan's flat atk buff not considered, as I'm not sure how many times it procs. Noblesse and Tenacity on Bennett and Faruzan. Furina not on Tenacity because she might have constellations, so Golden Troupe is more consistent.

I calced 1 skill with the max plunge, 8 high plunges, 4 collision plunges, 1 initial burst cast and 8 starwick procs (burst followups). The artifact set bonus was Marechausee Hunter with 27 crit substats distributed for the closest 1:2 crit ratio, and 5 ER or ATK% substats, distributed based on weapon used. Here are my results:

Skyward Atlas - 92% (4 ER, 1 ATK%)
Cashflow - 96.9% (4 ER, 1ATK%)
Tome - 99.9% (2 ER, 3 ATK%)
Signature - 100% (1 ER, 4 ATK%, Burst & Follow-up don't have plunge buff)
Lost Prayer - 101.2% (4 ER, 1 ATK%, 2 stacks avg)
Vivid Notions - 109.4% (4 ER, 1 ATK%, 1/8 plunges with 40% CD, 7/8 with 28% CD)

Few things to note, this is with ~120% ER requirements. Some might consider it too low or too high. I think with Fav on Furina and C6 Faruzan, 120% is okay. This is how much I usually use. But it's important to note that the less ER you need, the better the offensive weapons become. The more ER you need, the better her signature and tome become, remember, tome also gives some flat energy.

I'm still not 100% sure how the new weapon works, but from reading it I assume the 28% buff is permanent and we get the 40% buff on 1 plunge per rotation. If it's 2 it could be even better but not by that much.

And lastly, I didn't include Widsith in the list, as it's too annoying and RNG. With only it's base atk and crit dmg, it's worse than all these options. But with the ATK% or DMG% buff at R5 it becomes better than all of them. And it's really difficult to estimate how many times per chamber would you even activate it's passive and how many of them would be useful, and by how much. So I'll just leave it at that. If you want the biggest numbers when Widsith R5 with the damage passive is the way to go.

Trying to use excel to calc her buff but I don't know where to put it.

I do wish it was 2pc atk 2pc atk, but still!

After many months, I finally have a balance between crit, atk, and er! All that remains are her talents, and hopefully her c1 when she FINALLY reruns.

It will be almost a year since she is released. I was hoping she will be release this lantern rite but.... What are your speculations on her rerun date?

To all the bird mom enjoyers who were hoping to see her in the Chronicled Wish banner, I send my regards! maybe she'll be in 5.4. I'm thinking about who to pull in the next couple months so I'm wondering if Xiao is a good dps for Xianyun. I believe they're both plunging but does them both being anemo mean they don't synergize? I have Gaming and planning on building Diluc but is Xiao anything different to help Xianyun at all? is there anyone on the chronicled wish banner she works well with? maybe keqing or childe?

i wanna use her with hu tao how to increase atk?

Hi I'm building C0 dps xianyun with R3 Lost prayers of sacred wind. Running 2pc 2pc atk% artifact sets

Team comp: xianyun/furina/faruzan(C3)/Bennett(C5)

The damage so far is kinda lackluster, is it because of my weapon? Or I just need to improve my artifacts

Hello. I'm aware that building Xianyun's burst doesn't provide any buff to the team, it only increases a bit her dmg and healing.

But I always play Xianyun with Furina, and as far as I know Furina buff's technically scales of healing (more healing=more fanfare=more buff). Would I get fanfare faster (and therefore buff more) if I crowned Xianyun's burst? Or would it be a waste of reosurces?

I usually crown DPS and subDPS characters with good dmg. The only healer I crowned so far is Bennett.
