Blood Magick

Easily the most powerful form of magick after sacrifice magick, blood magick doesn't require something to die, as sacrifice magick does (ie, sacrificing a live creature. For a vegetarian, this may be setting fire to a plant, whilst it's alive... ok, I'll shush now) which is always useful when you need a powerful spell in a hurry. It's so powerful, when I had a rather severe nose bleed, and I caught the blood in my hand, when I flicked the blood in the sink and said "Set, bring a storm". That night there was a thunderstorm that spread from where I live to my best friend 38km away. This is no trifling thing, but at the same time, power is there to be used, not shied away from in fear. People often make the mistake of thinking the ancient peoples of the world had no idea that blood magick is "just as good" as sacrifice magick, and were just barbarians. This is ignorance on the part of modern people. They knew what they were doing and why they were doing it. However, sacrifice magick is largely unnecessary in modern life, we have houses to shelter from the worst weather, shops for the famine and piped water for the droughts. And the other purposes they used such sacrifice for, most of us will either never now, or never want to know.
For my part, I use blood magick, (my own blood, usually from accidents, not cutting or pricking myself, far too squeamish for that XD ) to further my own skills and powers, but irregularly, because it's rather draining on concentration, no other reason.
Women also have an extra magick use, and that's the menstrual blood. I wouldn't suggest feeding it to lovers to bind them to you, as I've read before (charming practice that DX), but it can be caught on sanitary pads, dried and used in spells, though with great care taken towards hygiene. Best to be contained within an item, such as clay, to provide power without being exposed to being touched, as even energy wielders are not immune to bacterial infection from such a ready supply of protein. Menstrual blood is highly potent, more so than normal blood, as it's the lining that would have sheltered new life, and is therefore more energy rich, as there are more nutrients. Being linked with many lunar goddesses, the sea, mother goddesses and all round fertility and prosperity, it's highly useful. Menstrual blood also allows for the mixing of blood magick and sex magick, though on this I have no experience to share.
That's all for tonight, g'bai :D
