Iron Blood Magic

Iron Blood Magic is a type of Caster magic. The user of this magic can use his or another person's blood, and make from that something kile weapon. The most mages could name it Blood-Make, but it is not. The user can use iron in blood, and "freezing" blood, makes it like a weapon. Also, user can use this "freezing" to his own blood, to stop the bleeding or even compress his blood to the point, that he will become "iron" to short time. (The user can do this, if his powers will reached the highest level of this magic).
