I think NY.Laegjarn might be my first 5*+10 Heroic Grail unit

I'm only 1900 Grails from being able to +10 her once she becomes available which sounds like a lot but hopefully they come out with quests and more (less expensive) bundles that rewards them. But mainly the reason for her is one she is probably my favorite OC from Hero's next being Eir, and two her Stat line kinda resembles that of Nephenee which is my main girl from PoR. So she kinda plays like a Nephenee on a horse obviously without that great refined weapon but it'll work

This probably would be the build I'd go with (if I can get 2 copies of W.Ephraim.... want one too keep, and got a spare copy of Su.Cordelia). If I don't manage to get either I might try to pull for Surtr for SS4 or just slap brazen Atk/Def or Spd on her for an A skill, then either Null Follow-Up if I manage to get another A.M.Corrin or just slap Desperation on her for the double Brazen combo
