4 and 5 stars..
So I just went to level 4 of the Hellfire pacts and drew a 4 as well as a 5 star D'wythe. I've been searching through the wikia but I can't seem to find anything concrete so I will just ask..is evolution similar to BB1 meaning is there a significant advantage in evolving from a 4 star to a 5? It seems like it would take a while to collect enough to evolve so I'm wondering what I should do. Any suggestions?
