It would be possible, of course, to max out her skills, but I would like to save my QPs, in case something good comes along. And maybe they’ll add a lottery soon, and that would be a plus, since I still need a lot of gems for other Servants.
There's that Quest from the Ordeal Call that gives QP.
You could take your time farming from it, 3 Quests a day till you've got lots of them...? (・・;)ゞ
I usually have a struggle to decide on which Free Quest to spend those Storm Pods on, if I didn't already have a huge chunk of QP, I'd probably farm there every day.
