So im a "new player" lvl 45 account and doing 5-1in the story Mode but If i remmember the game says u can only combine Chaos with other realm but the new event (the cats one) and It says that i need an aequor and a caro in the same team, i tried and It left me then i thinked It was only for the event but now i see that i can do It ANYWHERE so now i can do other team combination. Now someone can explain how realms trully work the mechanics of each one i understand but now i feel like my brain is melting
