I have two questions for you wonderful people: to be super useful in these maps, does Kagero need to be 5*?
And, considering I don't have Kagero whatsoever (my brother does), any advice on a team to beat the Navarre lunatic map?
My leveled (40 or almost) units:
5*: Caeda, Ephraim, Hawkeye, Minerva, Camilla, Nino, Takumi, Cordelia
4*: Stahl, Reinhardt, Frederick, Cecilia, Lissa, Clarine, Tharja, Subaki, Beruka, Palla, Olivia
Also, I have yet to acquire the 4* Navarre - should I focus on getting him before I try to kill him with himself?
