If you have one, use the phantom Gizmo/sacred crystal combo on Dolk.

First, try to get as close to 90% hp without going over.

then use all of your Sbb's to take her down as much as possible.

This will help you turn on her sheild because fei has so low HP.

once she has her sheild on, wait 3 turns to kill fang so she will only use Demon Atrocity.

then use Charla's bb so that the dot won't hurt as much.

then repeat each time she summons fei. But the proceeding times, try to get fei's HP as low as possible.

If RNG is bad to you, you may have to restart.

Good luck on getting Xie'Jing!
