While I have put up a quick reply I wish to point out to [@clanjo] that they seem to have misinterpreted Kafka's last post? He did not attack, merely stood firm with the others and brandished his weapon. But meh, how ever ya'll want to play the scene out is fine with me.


-----EDDIT-----

Um, Clanjo, the gems are bubbled still right? As in the same kind of bubble that Steven used to survive the crash of a giant space ship and its subsequent explosion? I personally don't think A low level sonic attack that was basically a load gust of wind would harm them much. 

But perhaps that is best left to the GM to decide. [@LokiLeo789], what is your call?
