^ my entire 4/5* roster. I also have 2 4* generic awakening gems and 1 4* skill gem.
I'm working on my roster to try going for elder's bane, I have 5.1 explored and one run through the rest of the act. Are there any particularly difficult paths I should know of before going in/any essential champs I haven't already ranked up? I'm planning to max my corvus for the collector fight unless I have better options for him. Also mephisto and iceman for certain paths. Are any of them worth awakening for exploration? Any other champs I should rank up/awaken?
