Great fire tank that can proc a lot of Qiongjiu assist attacks while also dealing really good damage (with dupes). F2P shouldn't invest into her as all of her damage is locked behind dupes and signature weapon.
At V0 she's only a Qiongjiu attack bot that can tank decently, but fire team has better dolls to use at lower investment anyway.
She can get to ridiculous level of damage at max investment. But v1-2 is the breakpoint you need, the rest depends on your budget.
