I could do the "Optimal thing" and pick a new servant (like Suzuka Summer TT_TT) but yeah... I'm still missing 6 copies of Circe to max her out, might as well get her at NP5. I was kind of hesitating with Don Quixote NP2, Elizabeth NP3, Fujino NP4 and Yu Meiren NP2, but I'd rather get my grailed servant at NP5 first
