Okay, that makes sense as to why my level 18 friend can't be added to my team, and my level 2 can lol. I am level 8 >.<
Yep you can always bring a really low level friend into a fight to get pwned. But you can only use friends up to 5 levels above you, for said stated reasons.
Soul crash is definitly a game where it helps to add more friends. So to really advance its really helpful to have more friends.
