Brackets to get crystal using artifacts?
Does anyone know base on what we're devided into brackets? In other words, how do I move from the current bracket (which can only see 3* artifact crystals) to a higher one?
Annoucement said "depending on your roster to get 3*/4* crystal..." but still unclear is it the total rating or prestige or smthing else..
Im not good or anything but with the main team of 4* 3/30 and above there's no point in getting 3* crystal using 3000 artifacts.
I want to know which aspect i should work on to get 4* crystal. Thanks
