SaGaRS: Spiral Corridor 260th Floor (Blackworm) 

Critical route via. Ward passive and S1 skill.
Ward is crucial in this fight. He's S1 is unique in this kind of fight.
Just survive the 1st turn and you're good to go.
Everything is smooth with this line up.
Matriach doing support stuff like healing giving attribute for everybody.
Minstral for atk and def boost that's inherited. You can use his S2 skill but 1 of your styles might be knocked out on 1st turn.
Katrina all around work.
Ward giving critical attack on everybody plus giving every atk, def, and attribute boost each time he attacks.
Tatyana is THE DPS MONSTER.
