Friggin RNG!
I just got Uncollected a few weeks back. I’m working my way through the end of exploring Act 4 and trying to 100% the UC EQ each month (plus the lower levels). That said, it takes me a while to collect enough 5* shards for a crystal. If I’m lucky, I get 2 or 3 a month. I have now pulled Karnak twice in a row! Friggin A!!
