RnG?
So are the crystals really based on RnG?
Don't think so
Reason:
-> It's almost like the game knows what we want and thus decides to give just the opposite (example of today- needed just about 24 units for another FGMC, opened about 40 arena crystals, guess what? The entire haul was nothing but gold, on the other hand, when I was low on gold and needed it, the arena crystals suddenly seemed to be wanting to give nothing but units, Bugged?
-> Opened a lesser solo crystal- 2* tech awakening gem
Opened a 3* sig stone- tech
Opened a 4* sig stone- tech
Opened a 5* sig stone-tech
Bugged?
