What attack on them??? I didn't attack them, I wrote that he's careful so he doesn't hit his teammates. I used the map you draw and they are standing between the star and the mob, meaning from the back or the sides I can hit the mob without hitting them.
yes they are between the mob and the Stars - meaning they are holding the Mob of the Stars in the Word HOLDING is the whole meaning. Panther is already surrounded by the mob, but as she went in AR they are just passing her, Freya and Mr. Anderson are one one side, they got even attacked meaning they are in Melee range.
Levitate is not Fling, so it is not as precise. For this i would use the grenade example, Levitate is as precise as throwing a grenade, and fling would be shooting a firearm, if you disagree name a good reason for two similar spells to exist.
Secondly you said you would use the heaviest thing you could - this means it's big as well. Something like 4x3x2m and 60Kg
Combination of the two brings me to think that you would endanger them anyway.
The other option is hitting the people who are bound by Caretakers spell and are neutralized anyway?
