Yanqing is a 5* Ice character following the Path of the Hunt. After using Skill, Yanqing gains the Empathic Sword Link effect, which reduces the probability of Yanqing being attacked, increases his CRIT Rate and CRIT DMG, and grants his Skill a certain chance of triggering follow-up attacks with Frozen effect.
The spirited lieutenant of the Xianzhou Luofu, and also its most proficient swordsman. He is born for swords and obsessed with them. Whenever a sword rests in his hand, none would dare to underestimate this genius still in the early days of his youth.
Perhaps the only thing capable of dulling his treasured blade's sharp edge is time.
We already added Yanqing's skills to his profile, so you can check them there, but keep in mind that the multipliers weren't revealed in the preview.

At the start of each turn, Frozen enemies receive Ice DoT. The Empathic Sword Link effect disappears when Yanqing is hit.
Technique - Master Fencer

Also, if you want to check his animations, you can find them in the official notice.
Yanqing has the ability to increase his CRIT Rate and CRIT DMG which means that he will work with lower-quality gear initially as the skills will make up for the lower stats. Still, same as with other DPS characters we need to see the numbers on the skills to know his potential.
