Within the series, blood is a recurring theme, and has been used for various spells and rituals. We have  a page for Tears, and I think the reason behind its creation, is similar enough, for Blood warrant its own page. It's also not always connected to blood magic, because that magic is specifically stated to  be based around a person's blooodline.

Examples of uses of blood include; Snowing's blood for Maleficent's ressurection, Lily's blood for Author Ink, Eloise collecting Rogers and Margot's blood for her ritual, blood for nightrot, Gold's blood for the Underworld, Regina's blood for the dark curse, etc...
