You know, like everyone, I was shocked at what it took to get the gold shrines. But a much greater shock lies ahead. You mentioned your Pans are at level 19 (what is the optimized production rate at that level?). Here's what it takes to get to level 19 folks:
15-16: 81,920 x 4 = 327,680 treats
16-17: 163,840 x 4 = 655,360
17-18: 327,680 x 4 = 1,310,720
18-19: 655,360 x 4 = 2,621,440
Total: 4,915,200 treats
It takes $1,000,000 to produce 20,000 treats. So you will need $245,760,000 in gold coIns.
I guess you can never say you are DONE in DV!
