Bone Magic is a lost caster type magic that utilizes the Wizards own bones.
Caster Type (Lost)
A magic that gives the user the ability to manipulate the speed of their bones' growth as well as the location of calcium deposits. This allows them to create weapons of bones that can either protrude from any part of the body, or pulled out and used like hand held weapons. The user is also able to create armour of dense bone underneath their skin. mediately after the bone is pulled out, the broken skin heals. Although it seems it takes a bit longer for the limb to become usable again or unless the user regrows the bones consciously. They can even fire pieces of their bones as long-ranged projectiles. Any bone that they remove from the body immediately regenerates, as does the skin that is damaged when the bones are removed. Users can increase the density of the created bones, making them stronger than steel. This not only makes the created weapons very powerful, but also makes their bodies virtually indestructible; the bones can withstand even a shockwave from magic force, which is usually enough to shatter through anything.
