I mean seriously not even once those have drop for me, what is the drop rate 0.1%?
As far as I know Nitocris shards only drop from Contamination Hell Overflow(reverse)...You don't get them from Nito raid
Just like the he said above. It's also 100% acquired rate if you complete OF Reverse.
4 shards every of run o/
Drop rate is 100% . You farm in wrong place if you don't have them.
