I just purchased Melody (by accident I didn't want to unlock that particular champ, but oops) and in my first match I used one of his skills I think its the R1 ability and a big red symbol stained my screen the whole game. Then it happened again on my second match with Melody and ruined that game for me as well, however I still managed to be awesome. So this is a bug, I won't be playing Melody anymore unfortunately a waste of some hard earned coins. thank you for your time.
