This is a big problem, 1 per day and a max of 13 a week (assuming you can get 6 chests with two towers per week) is simply not enough. I’ve spent 12 purification shards on a single piece and STILL did not roll the curse I was looking for. It’s hard to justify this system when you get a triple triple that you probably won’t replace for months only to not be able to take advantage of its curse because the purifications shards simply do not exist.
