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 spell is designed to influence others around you. To make them want what you want, to make them see things the way you see them. To influence them to come round to your way of thinking. This will also help with seduction, be careful though, it won't distinguish between male and female. And this is blood magick, it is designed to grow stronger and it won't leave you. Blood magick can be dangerous in and of itself. But you will gain influence over others and be able to seduce as good as any incubus or succubus out there.
