@Rye The recommended weapon for Xiao would be Blackcliff since the stat that levels with his ascensions is crit rate. The other weapons could work but a physical damage build isn't that good on him so you'd always want one focused on stacking his burst and anemo damage. Favonius is alright since he does have trouble with his burst uptime cause he doesn't generate particles in his burst form, but doing that would mean you'd need to farm a lot more for good artifacts.
For the artifacts you should use, since I'm already talking about his build, you'd want the 2 piece anemo set and 2 piece gladiator. For the sands of eon, you'd want atk% as main stat, goblet you'd want anemo dmg bonus, and the circlet you'd want crit dmg. The substats you should prioritize would be crit rate = crit dmg > energy recharge > atk%.
Btw, the reason this build is best for him is cause his plunging dmg multipliers are incredibly high and you'd want to abuse that as much as possible. That's also why you should level his normal atk first, then his burst, and then his skill. His plunges in burst form also have the added benefit of being an AoE atk that deals two sets of dmg, one for hitting them with the plunge and one for the impact from hitting the ground. That's the other reason why his anemo build is the best one.
As my final closing statement, some advice on how to maximize his damage is by animation canceling while you're plunging. You do this by pressing attack and then immediately jumping before pressing attack again. The first hit Xiao does is 2 movements, so you can practice outside of his burst by trying it out normally. You want to jump before the 2nd movement starts. If you use his burst like that, then Xingqiu's and Beidou's bursts will work with his since he gets a normal attack in before plunging.
