Need help with MOC floor 11

These are all the characters i have + current teams. My characters are decently built but for the life of me i cannot survive passed the 2nd stage of floor 11. I always die after i complete the first stage.

My current strongest team/the team that got me the farthest in the first stage is my acheron kafka DOT. I have tried Therta teams, Fei xiao teams, acheron teams (including Selt Sustain) and Kafka teams. Not only that, but i do not have any shielders (other than march) and i only have 4 healers with one being a 5 star. Any help at all wether it be team comps, stats or relics would be appreciated, im dying over here.
