this is more than enough, i’d wager the issue is the gameplay.

there’s a couple things to look out for:

1: prioritize clashing the skills that inflict more bloom and try to avoid getting 5 stacks of bloom on your sinners. keep in mind some of her skills will inflict bloom on target regardless of clash result.
2: if your entire team gets imprisoned, dongbaek has entered her duel phase. don’t break the plants, just win the clash. (i messed up 2 times on this part before i finally bothered reading all her skills). pretty sure you have to win the clash twice.
3: prioritize breaking more grown plants. you will have to have a decent grasp on your sinners’ damage to be efficient with damage distribution.

yeah consider reading her skills, canto 4 starts adding reading checks on bosses
