You can collect jewels without spending money

6300 jewels obtained solely through the album completion event, without any spending. As a free-to-play player, I had to invest a tremendous amount of time. Thanks to that, I now have 27 pouches of level 5 jewels in my storage. Before this, I was always short on jewels, which made it hard to clear missions and participate in events. It's a relief that I now have more than enough.
