Is it no longer possible for me to get Artoria Lily?
Joined the game recently so I'm afraid i'm probably never gonna have a chance at getting a hold of her
And it was possible to get all 5 copies with a new account and only underleveled Fergus and Siggy as sabers at the start. It was really hard, but I got through to np5. I found a way to (barely) farm the Jeanne node, mostly because her np didn't slaughter me. When I started she could fire the np 2-3 times, but as I got my servants leveled I eventually got to where I beat her before the first np.
Saber class gets attack up bonus and a point drop reward (unless it was just the CE's that gave the attack up) so the more sabers you can field on the more difficult nodes, the more bonuses you get on the point drops and the faster you earn the rewards including the copies of lily chan. So it takes a LOT of grinding if you only have 2 weak sabers at the start. Got easier when I could add lily to the mix, but I was sooo disappointed when I couldn't field my second copy of lily for the saber point bonus because you can't field identical servants...
