What is the minimum level needed for champions for Raids?
Currently I can easily do the light SW in 1 min, but when I move to the different elements I start to lose often enough where it is pays off more to jump down back to SW4. I am trying to farm adept gear.  Are those levels possible with 4* champions equipped with the right gear, or do you need 5* champions for SW5-8, and 6* for 9 and above?
