Infections are killing my save file at the moment. I used to be able to beat them no problems by just making my heroes better, but now, they level up with you. My team sits at roughly levels 107-108, some are in purple tier while some are orange tier (my strongest hero is O2 and my weakest is P0) and most my heroes are around 3-4 stars.
My infections, however, are level 120, O5 heroes at 5 stars, so of course I can’t beat them. I’ve been trying to improve my heroes but the infections keep leveling up with me. I’m now currently at the point where it is not possible for me to get any more badge bits for any of my heroes. I can level them up and level up their skills, but then the infections will just level up too.
How do I clear these infections so I can progress again? I’ve been stuck for weeks now.
