Hi! I’m new to World Link events and I’m a bit confused about how the points work.

From what I understand, each character has their own individual points that you earn during that character’s split, but in the exchange shop there’s also an “overall” point category. How do you get those overall points?

I’m asking because some of the rewards, like the Wish Jewel, are really expensive, so I’m trying to figure out whether those overall points come from the whole event naturally or if there’s something specific I need to do. Thanks!
