P.A. really.. why?? Chaos crytals should have been in the forefront of yall minds for rewards in hadum boss for eg. every 10 lvl you get mayb 100 chaos crystals...

You re looking at wrong place bro. You can find that chais crystal in hadum by farming and offering in the black rock shrine. And in the great desert by offering in the black rock altars. And on your daily black spirit hadum quest.
