For just the "okay at best" servant to be permanent you only need a few hours and at most a half day. Doing the shipwreck quests and following whatever is the cheapest and most balanced route will allow you to do almost the entirety of the storyline - although you will do a few runs outside of the shipwrecks to replenish a bit. You end up not grinding much at all. It is what I did. You should probably skip the story, though.

I had no event CEs, save from those from the support.
