During the event, as long as you successfully clear missions at a steady pace or on schedule, you will, without a doubt clear the event shop even if you have 0 event currency (gacha) CEs. The whole event centers around gathering as much QP as possible to advance the event’s story.
You should only have or put as much QP related CEs in your party as possible to maximize your QP intake to attempt to climb out of QP hell.
Bella Lisa (5℅ QP in party, 15℅ QP as support)
Mona Lisa (10℅ QP)
And the less owned - Detective Fou (5℅ bond, 5℅ QP)
As well as Heavenly Demon Princess (Event QP mob appearance)
Your event support list should look a little like this with the other slots filled with new Summer Servants (
or merlin, but I don’t have him, hopefully yet).
You don’t really need to put Heavenly Demon Princess on your Castor supports cuz if you’re already filling your party with QP CEs and choosing Bella Lisa held supports, you won’t need to worry about QP. Just doing that can’t net you 400mil+ QP farming normally.
The other event CE, Midsummer Memories, is a very beautiful CE, but not all that necessary until the Challenge Quest. Even the Shimosa-esq battles can easily be done without it and soloed with the welfare servant, Hokusai (Saber).
Hope this has been informative to those wondering about Summer 4 QP related things.
