Blood is a liquified substance in some organisms, like humans, that carries oxygen throughout the body. According to the Book of Shadows, warlocks do not bleed when wounded, implying they do not have blood in their bodies. The substance is drunk by vampires, who require it in order to survive, and it is also used in several spells and potions, either for blessing or as an actual ingredient.
The warlock Nicholas possessed the power to boil blood and kill his victims from the inside. When alchemists transmute an individual's blood, previous spells or potions based on that blood will be rendered ineffective, as was the case with the Belthazor vanquishing potion.
Individual Information Edit
In Witches Edit
In Demons Edit
Upper-Level demons have red blood, while Lower-Level Demons like Scavenger Demons bleed green. However, the Source of All Evil bled black. When a Demonic Alchemist transmutes the blood of a demon, it renders all potions and spells derived from demon's original blood useless.
In Warlocks Edit
In Gypsies Edit
The blood of a gypsy is used as an ingredient in several potions, including the vanquishing potion used by Pilar, Phoenix and Patra on the Slave King and the To Separate a Witch from Her Powers potion.
In Vampires Edit
Vampires require blood to survive, and use their long, sharp fangs to draw it from the veins and arteries of human beings. Should vampires drink blood while in bat form, it converts the victim to become one of their own.
Spells and Potions Edit
- To Call a Lost Witch: Blood is the final ingredient in this ritual, and is spilled into a cauldron with Rosemary and Yarrow Root before the witch chants the last two lines; blood to blood, I summon thee, blood to blood, return to me.
- Spider demon vanquishing potion: The Charmed Ones used their blood to bless the vanquishing potion they mixed to kill the Spider demon.
- The Slave King vanquishing potion: In the potion used by Pilar, Phoenix and Patra to vanquish the Slave King, Gypsy blood was mixed with Henbane and Mandrake Root as an ingredient.
