I changed it.
I only specified "unbanded" because there was some confusion up here about access. Say it's a green site, and the battle is won by a banded green, white and gold hero. Someone might say that its still a "lone" hero rescuing the lost soul, because the other two do not have access anyway.
Same thing with Claudia banded to Simeon to rescue the Female Only. It's only being rescued by a "lone" hero because only 1 hero has access (or so goes the argument). I get what you're saying, and agree with it. We all just need to understand the term "lone" to mean "unbanded" rather than "the only hero with access to the lost soul". Thanks for the help.
