Blood Magic

Blood Magic is one of the most controversial kinds of magic powers and is almost always linked to Dark Magic. As one of the primordial magic powers, it's known that once blood magic that involved sacrifice was the only option available, but as centuries passed, users of blood magic are criminals in every kingdom of Thorodon. Sometimes, this kind of magic is called "red magic" but Merlin himself dislikes this term due to a possible minimization of the destructive powers this magic has.

Self Sacrifice
One of the most common ways to use blood magic is through self-sacrifice, usually involving drawing your own blood so a spell can be cast or even going extreme lengths such as removing a part of your body or mutilating your body permanently for the blood spell to become stronger and longer.

Person or animal sacrifice
There are few registers of blood mages who actually kills people to complete their rituals, because most of them know that by doing that Merlin himself will go after them. Merlinus used the lives of many people through a blood magic sacrifice so that he could save other people.

Animal sacrifice is preferred, as it produces a lot of blood magic potencial but without going so extreme like human sacrifice.

Known Users

 * Merlinus
 * Hella
 * Malitious

Pros

 * Once the sacrifice is realized, Blood Magic easily becomes one of the most powerful magic powers, with long-lasting spells and curses, as seen with Merlinus curses.
 * You can save a life if that means killing another. It can be useful when saving a friend when killing an enemy

Cons

 * The sacrifice itself is not a quick process, so using blood magic in battles can be quite stressful when the technique is not mastered
 * Doing it the wrong way and draining too much blood from you can possibly kill you, be it during or after use
 * It can quickly become an addiction, not like most magic powers
