So has anybody tried the Narcian map yet? It was pretty difficult but I think it was really good. I ended up beating it on hard on my third or fourth try. I was barely failing because my Takumi was Lv39 and was missing just 1 DEF that would've kept him alive near the end. I had to grind a little bit and then I went back and repeated the same steps I did on my near-successful attempt to beat it. You really need someone with lots of defense to initiate the battle, one that can't counter from 2 range preferably.
I pulled a 4* Lilina that I might train up because of her huge ATK, but I do really like Caeda for being a flyer and having Rally Speed.
Also the greet thing can be done once a day, you get 5 feathers for doing it and another 5 feathers if at least five of your friends also greeted you.
