Soloing it wasn't a problem - I just wanted to make sure I wasn't misunderstanding or misusing trust magic, since the alter ego wiki entry (http://ffxiclopedia.wikia.com/wiki/Alter_Egos) made it seem like just anybody could summon alter egos in battlefields, including the one for "The Holy Crest."

Sounds like I have to finish that rhapsody section - umber it looks like? - to be able to use trust magic in a battlefield.

Thank you.
