Yes but I've found that if I reborn at stage 100 back to back to back even if my hero level is the samethe amount of crystals I get drop original I might have gotten 100 then 80, 50, 30. I was wondering how it was calculated, the hidden numbers.
For example the hero level I have to hit to get on crystal started at 100 now it 1000. Not only do the price get stepper as you buy more but you get less and less for you efforts.
