Guess I should have included that information, sorry. Here it is, hope it helps:
Raiko (3/4 stars)
Mammon (3/4 stars)
Gryla (2/4 stars)
Baal (2/4 stars)
Off team is Pluto (0/4 stars) and Meretseger (0/4 stars)
Incidentally, I also have an Azrael (0/4 stars). I was wondering, is it worth swapping out somebody in my main four? I could raise the level, just haven't because I've already raised both Gryla and Baal up to 2/4 stars. And since I'm strictly casual, I'm not exactly rolling around in spare parts
