Yunli FAQ (V2)

Best Light Cones?
Without External Taunt
Sig 20.1% over DHIL S1
Sig 27.3% over Aeon S5
Sig 28.0% over Clara S1
Sig 29.0% over Blue Sky S5

With External Taunt (Lynx)
Sig 12.4% over DHIL S1
Sig 19.3% over Aeon S5
Sig 21.2% over Clara S1
Sig 21.2% over Blue Sky S5

Note 1: If you play her with DHIL S1, you will need to have a basic-skill rotation on Yunli to maintain 100% uptime on the LC buffs.

Note 2: If you want to use Blue Sky, aim for a CR of 70-76% to prevent over-capping.

TLDR: Sig >> DHIL S1 (2nd BiS) > Aeon (Best F2P) > Clara S1 (Best Standard) > Blue Sky (Best 4-star)

Can salsotto's buffs stack because her ultimate counts as both ULT and FuA?
No.

Best Planar Set?
Duran is BiS but here are some alternatives that are very close in performance:
Inert Salsotto (4.4% diff)
SSS (7.0% diff)
Izumo (9.1% diff, even if you don't have another destruction unit on the team)

Best Relic Set?
Wind-Soaring Valorous is BiS, alternatives are:
Pioneer (1.9%/5.5% diff, assuming you can maintain 2/1 debuffs on all enemies)
Duke (3.6% diff)
Streetwise (4.5% diff)
2pc Street 2pc Duke (4.6% diff)

ATK vs ERR rope?
It depends, content with a lot of enemies like pf may see ERR rope having slightly better performance, but in general ATK rope is better.

SPD vs ATK boots?
ATK boots are 7.1% better, you risk losing LC stacks while running speed, and the extra energy from extra turns is marginal compared to energy from getting hit.

ATK vs PHYS orb?
PHYS orb is 1.0% better. Use the orb with better subs.

What are her best supports?
Robin (120+ spd), slow Yunli: Robin is her best support by far, huge atk buffs, decent dmg% buffs, action forward, 25% FuA CD buff, the complete package.
Tingyun (160+ spd), slow Yunli: This setup provides very similar buffs to Robin, with some additional energy gen.
Sparkle (160+ spd), slow Yunli: turns out losing LC stacks is no biggie if you can get a monstrous 48% dmg and 100+ CDMG from sparkle.
Ruan mei: RM loses points because delay on break gives Yunli less counter opportunities, but is a solid option nonetheless, especially if the content has many non-physical weak-enemies.
Pela: Yunli has a lot of self buffs in her kit, so its decently beneficial to go after the enemies's DEF instead, unfortunately pela isnt a 5* so her scalings aren't as potent.
Bronya: similar logic to Sparkle-Yunli, but a lot worse because its taxing on your sp and her skill buffs dont last for the duration of Yunli's counters.

What are her best sustains?
Huohuo: Extra ATK and energy on ult, cleanse for days.
Lynx: Provides additional taunt via her skill, she is essential imo if you do not have Yunli's signature.
Luocha: healing on counters essentially makes you immortal, can be built fast with multiplication for infinite sp.
Aventurine/Fuxuan: Do not be afraid of preservation chars stealing aggro from yunli, as long as both yunli and the preservation are side-by-side in the team, there will be barely any difference.

Why are the numbers so different from V1 FAQ?
We are now considering team performance rather than Yunli's solo performance. Improved enemy mechanics and also implementing block state taunt massively improved non-sig LC performance. Additional parameters (res, break uptime, break delay, etc.) were also introduced to better simulate actual battle conditions. If you have questions/want the actual numbers, feel free to ping/dm me.
