Xingqiu is one of the many underrated characters in Genshin Impact. I like using the Noblesse Oblige set on him compared to two sets of Attack Percent. I also added his voice lines in this showcase just because. How do you build Xingqiue? SHOW MORE BELOW!

-Artifacts for Xingqu Main Stats
Flower Default
Feather Default
Hourglass ATK%
Hydro Goblet% (I'm only using 4-star.)
Crit Damage Mask/Hat% (I'm only using 4-star.)
If you get 5-stars of these you'll do more damage!

Xingqiu Artifact Sub stats
ATK%, CRIT Chance%, Crit DMG%, Ele Recharge%.

Artifact Builds for Xingque
Full Noblesse Oblige Set (Good for Abyss)
Split 2x2 Attack Build Artifacts (Flexing Damage)

Xingqiu C4 gives 50% DPS on his skill for more Flex.

Using your Ult before Skill Does Big DMG! (Thx Mike)
Triggering Vaporize Gives Big DMG!

As for weapons I'm still experimenting, not enough resources.
Some weapons have Phys% which isn't good for a Hydro Xingqiu.
