Regina using Emma's blood to find Henry

Blood Magic refers to spells that require a certain type of blood in order to be activated or deactivated, featured on ABC's Once Upon a Time. Generally, in most Blood Magic spells, it can only be accessed by the user or a blood relative of theirs.

Blood Magic is linked to a person's bloodline and can be used in a protection spell for hiding items from those who aren't of the caster's bloodline. But this also means that the people who are of the caster's bloodline can easily approach or attain the said protected element. This method can be used to seal areas, locations or objects.

It can also be used to track someone linked to a person's bloodline, through use of the tracker's blood, with an item that provides insight geographically such as the Blood Globe or an ordinary map.
