Pretty cool and very thematic. Honestly, I'm not too familiar with how powerful Lunars are supposed to be but the cost seems way too prohibitive. Ditch the Willpower and Health level cost for sure and I'd even consider getting rid of the mote commitment, especially if the lunar chooses not to change the compulsion. Its a fairly low level mind control charm by exalted standards (don't get me started on the Far Folk
). It only has one target, doesn't permit complete control and has quite a few levels of detection. Its strengths are its duration and range but it seems too complicated to use often.
