Why Blood Magic Is Powerful
Because it proves your devotion.
Many witches perform spells with a mindset of, “Well, it’s just a few cheap candles and herbs. If it doesn’t work, no loss.” But when someone is willing to hurt themselves in the name of a ritual, that proves their faith in what they are doing. And as I have said before, such faith is what truly makes a spell powerful.
Because your blood stays alive.
Your blood is your conscious agent. When sealing a pact between you and another by mixing your blood with theirs, your contract becomes binding. Even if, in the future, you no longer feel like honoring your vow, that part of you which you spilled always will, keeping you loyal to your pledge. And thus, giving your blood is a testament to your lasting commitment.
Because blood serves as your identification.
Bloodline is not everything in witchcraft. But it does matter, because we can inherit the powers of our ancestors. And because there may be entities connected to your family who might be willing to work with you. Using your blood helps activate any suppressed abilities that may have been passed down to you, and becomes an invitation to entities who are attached to your lineage.
Because a person’s blood connects you to them.
If you are performing transcending magic (i.e. binding/unbinding and manipulation/control spells), then having a drop of your target’s blood strengthens your dominance over them. Much like a Voodoo doll would. Except having someone’s blood extends your influence beyond their body to their thoughts and emotions.
Because blood is life.
As discussed above, a drop of human blood, when willingly given, is a dose of commitment. When presented, it is a method of identification. And when secretly taken, it is a means of control. Which is why, just as water nurtures plants, and food nourishes humans, blood feeds occult forces. It connects us to supernatural sources who enjoy witnessing our pure essence.
Contrary to what we see in fiction, blood magic has always been performed with the best health precautions available to practitioners in their era. No real witch ever just took out a knife and slashed their palm casually. Blood magic has always been treated with the utmost respect. It will not work for those who neither understand nor revere it.
