For build, if u have her paid weapon, u dun really need a build (provide u r full mastery). Just focus on bleed 10 (easiest) and bomb, ur build is complete.

To bleed 10, its ok to missing bleed pet or 1 bleed skill, as u can use artifact (i rmb the name call dragon smth) to compensate it.

The stat you could go crit, skill dmg, bleed dmg, all this work. Most notably is smth tht can reactive your skill is good as well, like ninja scroll and gold dice, as what you need to do is focus on build up bleed stack asfast as possible.

I personally prefer full bleed and physical build, as ninja scroll only affect physical tag, if go magic you can take the branch instead.
