After a long and hard journey, I've completed Act 8 and ranked up 2 champions to gain my first and second maxed out 6*s. Valiant is still far. I have one 7r2 gem, and NO resources to get to r3.
I have Act 6, 7 and 8 unexplored. What should I do next?
In special quests, Abyss, Necro, GGauntlet are to be seen, but I don't have the champions to attend to them, even after mass rank-ups focusing on these special quests.
To ask again, where next?
This is my roster.
