actually one of the most bad ass and scary things i can think of that would fit a more combat oriented molly would be something akin to the Battle Meditation from KOTOR one or two, anyways the person focusing the battle meditation creates a hive-mind construct that every one on your side shares while fighting granting each participant the benefit of knowing whats going on all around and access to this kinda of shared knowledge base regarding the fight.
that right there seems like it would be one of the more grey areas/awesome ways to go with mind magic.
just think what chicha iza would been like if every one on team dresden had been linked.
