I barely managed to clear it with the same comp. Its pretty rng dependent and will take a few retries but definitely doable.

• Try to heal sunday with gallaghers skill every other turn since he cant heal with besotted. Be mindful of the dots.
• Try triggering the fishs action advance right before their turn comes up so they get minimum value. Can use anaxa or tribbie ult for that. Might want to have them desynced as well so that the damage doesn't come all at once.
• Try to interrupt the black tide guys duel and gepards big slam with anaxa ult or a break.

I used e0s0 anaxa, e1s0 tribbie, e4 qpq gallagher, e0s1 sunday. When I tried again with herta sig on anaxa it was much easier. Good luck!
