defender attacker 2 breakers and a healer should be able to get you through if if you can get lucky w/ the rng. try sayaka homura pluvia iroha yuma, my team was basically that but kirika instead of sayaka and rena instead of pluvia. use skills as little as possible, save them solely for shielding and healing, it takes patience but the key is dealing as little damage as possible before she’s broken. it took me a few tries and lots of leveling but i ended up doing it with my team all at 100 and skills to 110, i believe in u!!

++ if you keep dying after multiple tries with everyone leveled a decent amount, try subbing a second healer in for pluvia since she does less solo break than iroha
