Koei has had a difficult time deciding on what weapon to give Yueying for a long time it seems, but for this game the weapon is actually really OP. Her Launch Trigger is your main tool, the Flow attacks that follow are really powerful and should be spammed at all times. Knock-Down and Stun Triggers are really good poking tools. Stun Trigger is imbued with Lightning and cannot be overwritten, changing the element through Gems will only affect the Flow Attacks that follow. Ground Musou is freaking dumb, the blender attacks before the cinematic are incredible, use it against any enemy type (even gates) and you'll be good.
PS - Fighting on mountain terrain is stupid.
--
I pick Gem elements based on the character's Musou and Special attacks.
Why not Musou difficulty? Because it's just a grind fest, not actually difficult. You also get the same experience rewards as Ultimate.

ICONIC, I hope she keeps this weapon & move set 🥺

Though I miss her dagger axe myself, this moveset is really strong. Koei is probably gonna change it though just because they'll keep changing her like they have been until the end of time.
