Secret Chamber daily event is one of the most important and it is very buggy. Your rewards depends from the damage you give and all players enter the chamber at different times. I always feel that I enter there as the last person and never make damage because of it (that makes me get the worst rewards all the time). You need to solve that. Secret Chamber system cannot stay like this, it is very unfair to some players like me. As soon as the system changes fairly I will change my rate.
