Arknights | NL-9 Trust Farm 3 Ops (Passenger, Ptilopsis, Warfarin)

Passenger is borrowed to prove you don't need pots since mine is P6. Warfarin and Ptilopsis skills aren't used, only E2 Lv1 is needed for their talents.
Operator levels:
Passenger (Support) Lv90 P1 S3M3 + module (module is needed but I don't think he needs max level)
Ptilopsis E2 Lv50 P1 S2L7 + module (module not needed, skill not used)
Warfarin E2 Lv1 P3 S2L7 (P1 is fine, skill not used)
It's also possible to just put Skadi the Corrupting Heart (S2) behind Passenger for a 2-op trust farm, but she's limited and much rarer, while the two medics here are more common.
