ningguang if u want to use (c1/c2) , use her as field explore/domain unit. She crush everything in that aspect except vs shield or geo unit. Suffer in abyss unless u got vacuum unit like venti.
She need bp cata or the 5star cri cata to be a proper dps, else jz bench her or jz use prototype cata as healing support.
Team 1 - diluc , healer (barbara/bennett/qiqi) , 1 random pyro unit , 1 shield breaker unit. Put chongyun in for E buff if vs fire slime.
Team 2- klee, healer , sucrose (vacuum support/pyro resist reducer) , shield breaker unit.
on field/domain explore - diluc , barbara/qiqi, bennett/pyro unit,
focus on diluc first better, coz if u met fire slime ur klee cant do shit. Xingqiu Q is op with pyro unit (diluc / klee). Bennett top tier support and healer as well, get him from shop
c5 noelle is kinda useless for u since c6 then she become a proper dps, c1 on ward is just a support/healing unit.
on paper , klee and diluc means u already endgame abyss f12 ready, but thats more of a whale line up. Ur line up lack another element dps , u might even cant pass the fire slime floor. Last choice is your razor c2 (chongyun work but u need read more about that in reddit/guide). Usually for other ppl will be venti + fischl, fischl alone without C6 is kinda weak.
I have a venti/fischl account but I don't have proper DPS main even then I find it easier to ascend spiral abyss than with my current lineup.
