I know, but I have him at NP 3 I believe. So that must've come from somewhere. I probably rolled the story banner near the very beginning and forgot, in retrospect. I wasn't aiming for specific Servants or worrying about limited rate-ups when I only had a Carmilla, Martha, and Marie Antoinette -- I just wanted something to cover the classes. I still don't have a SR Berserker technically, though I grailed Kiyohime to 80 for her ability to farm Events with Mash's extensive protection and the Chaldean Uniform.
It does explain why I haven't gotten any other Bediveres or Jaguar Warriors though. I just assumed they were slightly more rare - like how I very rarely get a Kid Gil or Hundred Personas - but I definitely haven't done the story banner since beating Camelot.
I would like more Bedivere NP levels, he's a solid Servant judging by using him with maxed-out abilities and a couples of grails. I don't want to leave him in my Second Archive really, I'm just not sure if the SQ is worth it now that I know what banners are coming.
Congratulations. I've been switching between them and raising them individually one level at a time, I expect to be done by Christmas 2021 maybe.
I'm glad the additional mystic codes seem to have a much lower XP bar. If they were all like that there would be a degree of "why bother" at some point, as experimenting with new ones would feel terrible.
