Think this is the best I can do for now. I know the CR and ER are both low as fuck but the crit damage is to good to pass up. Gonna keep on trying until I can get a gold crit value but that's going to take a long long time. Only cope I have is that my Carth is S6 and can oneshot every boss without needing to ult twice so ER isn't that needed, and the echo set provides another 10% CR.
