Blood magick: Demon in your blood :Xtreme
This is the Xtreme version of that power and comes from my personal BOS, the power this gives is Xtreme and if you can't handle it, it can drive you a little nuts, and there is no reversing it once it starts. Blood magick in and of itself is dangerous enough, add Xtreme actions to it, and it becomes a force to be reconed with.
This one comes with a warning label.
This will give you the power of any demon in your bloodline, in your past or your bloodline's past so be aware of this beforehand, A demon will also come with this to help you handle the power. It does not matter what that power was/is it will give it to you weither you want it or not.
DO NOT do this unless you are an experienced BA companion.
