Kerria and Enotera are both very good. Only can fit one of them on a team though.They eat you out of house and home
They just are such resource hogs and have voracious demand for skill act and have no crit and like debuff. A tall order.
If I had Nerine Christmas, I would definitely put her in with her and would be interesting to build on that.
Still would take a 3rd team to beat the boss with what I got. Dont have a counter team to test.
