This is the Xtreme version of that power and comes from my personal BOS, 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 itself is dangerous enough, add Xtreme actions to it, and it becomes a force to be reconed with.
This is dangerous and can lead to astral travel without conscious thought if not carefully planned out. You will find yourself out and did not mean too. Astral travel can become addictive as well. On top of that, this is blood magick and should be treated with reverence and respect. This will change your genetic makeup and make astral travel a whole lot easier.
