So I am currently around level 45 with my main character and I am working through the West Midlands Underground.
At the moment there is a PvP event going on which I am actively taking part in. However, sometimes when I select my opponent I notice that they have a set of 4 familiars to battle against. How can I get this too?
I have already unlocked a couple of additional formations, so my best guess is that at some point I will get a 4-man formation. If this is the case, when will I get my first 4-main formation, and what other formations are available? (Note: I think my latest formation I got was "Wave")
Also, can you get more than a 4-man formation? I remember last week there was a different kind of event which had some sort of boss battles (large enemies) that allowed me to field 6 of my familiars at once. Is this just an event specific formation perhaps?
Perhaps another interesting question: once I have access to a 4-man formation, are there any motivations for me to ever go back to a 3-man?
