NOTE: Abuse any of these powers (use them in ways you shouldn't) and you will lose them.
It isn't common knowledge on how to defend against them, meaning if you run into one of these powers in RP, you don't know straight away what to do, also if you are a Sith who is using these powers you do not just happen to know them all of a sudden you must learn how to use them, RP out training in them.
