I'm mostly after the life crystals, but got to 2,908 fireworks by now. At 3,600 I think I'll stop taking the Secret Gardens, and just see where I end up while still farming for the life crystals.
109 crystals to go for the second Gold Skill Bloom.
Would the 11/27 exchange date for life crystals in the store be this month or next year? I'm assuming it's this month for now, and will just stock up on crystals again until that date.
