The new 6* Konagi is definitively the answer to lvl80. Pierce, -ATK -DEF, +ATK +DMG up to 150% for herself, Skill act, HP drain, Guts. She can do it almost by herself with Lycoris Memory.

I got my perfect Cardamine and I almost cleared that level. But I still lack of a little something. I just need a tiny bit more of atk power or a great luck on targeting. I pray for an Halloween Peony reword next week. She use an halberd. She MUST have Pierce weakness bonus.Right now she is just bad.
