Blood Magic

Blood magic is one of the most forbidden forms of magic, and it is easy to understand why. Rather than using the divine chaos that filters into our world from the heavens, these spells use the very lifeforce of humanoids and other creatures to fuel magic.

A single life is, apparently, filled with immense power, far more than a normal sorcerer can channel through a ley line. This means that blood magic enables spells of incredible ability, but at a horrible cost.
