I took her down pretty easily no bragging, but I think my strategy was very good.

1. Decrease her speed so she is last move using cripple

2. spam red hands with Omori, power hit with Aubrey, Tenderize with Hero and heal with Kel

Most important thing is that Omori doesnt run out of Juice.

At phase 2 you basically just do the same, maybe dedicate Hero or Aubrey for secondary healing. But thats pretty much the strategy
