Cacao has been a wonderful enemies as well as greatest AoE arcwitch damager. How could we survive through her attack?
I used a team of five card of the following
1 Calamity UR maxed 29999
2 Penemue HSR normal stat
3 Omoikane SR
with Penemue pro for 3 times, the Calamity only hurt 50% of Cacao's AoE, and others except Omoikane survive and then Cacao recover all. Then I use about 24 rounds to finish her
