There's no RNG with servant abilities. Every Euryale starts with the B- NP, and it get upgraded to B after whichever quest it's linked to. Sometimes it's an interlude, sometimes it's a strengthening quest. That's how it works for every skill or NP with an upgraded version for every character. It always starts out with the weaker version and it becomes the improved version after a specific  quest.
