Siphoning is the distinct ability of Siphoners and witch-vampire hybrids to absorb magic from another source other than themselves, unless they're a hybrid. The source of magic can come from almost anything including other witches or supernatural beings, bound spells, enchanted objects and even vampire blood.
This ability requires physical contact and when activated, it gives off a faint red glow. While in some instances the process of siphoning has been known to cause intense pain, other instances have been painless.
