Tower buffs her alot but she usually does 13k in open world. I expect a little bit more with more copies of her on Yinlin's banner but overall should be used as a support. Unless you're me ofc :))))
JUSTICE FOR TAOQI!!! Yesterday I watched a rank video on WuWa characters and they said she's useable. It's crazy! My Taoqi is hitting for 15k to 20k DMG.
Crit is always better, dmg is calculated using def and then crit is used as a multiplier to increase the dmg The 1 costs should be def, 3 costs havoc dmg and 4 cost crit (whatever is needed)
My only 4 star long sword has defence as a main stat so i put it on her and i'm trying to figure out how to increase her damage I have everything on def wherever i can get it maybe I will try upgrading all of them, I did got Dreamless and he got def as main stat and def percent in its substats lol so I put it on her
