Helios Dragon Slayer Magic

Iron Dragon Slayer Magic ( 鉄の滅竜魔法  Tetsu no Metsuryu Maho) is an advanced caster type magic, lost magic and Dragon Slayer Magic, taught and developed by dragons with the sole purpose of slaying other dragons. Iron Dragon Slayer Magic is one of the more adaptable kinds of slayer magic that there is due to the sheer adaptability that the Iron possesses through a variety of "modes".

Desription
Iron Dragon Slayer Magic, as the name would imply, is a magic that utilizes, primarily, the powers of iron in order to slay dragons. This magic, more than simply allowing the user to utilize iron, it grants them a supreme control over the element, enabling them to not only make use of the iron that they create but rather also the iron around them. Upon learning this magic, the user will realize that their body will experience a few changes. Stronger jaws and corrosive teeth which enables them to bite through and consume metals in order to replenish their strength, a hardened body which can endure even more trauma than a traditional human's body would be able capable of handling. The users of this magic can, like many other slayers, produce their element from their body, making as an extention of oneself. However, much like other metal based magics, the mages with this magic can produce their iron from thin air, disconnected from their bodies, allowing for greater versatility. More than that, the metal that is produced by the Iron Dragon Slayer is a "growing" metal. This means that the metal will gow both in strength, hardness and sharpness as the mage him/herself grows in power. More than that, it would seem that the iron grows powerful through sheer determination as well, meaning that the metal becomes stronger with their passion for whatever it may be.

Dragon Slayers with this magic are capable of more than simply consuming Iron. With enough discipline and practice, Iron Dragon Slayers can consume various other metals or elements in order to unlock a new mode with brand new effects to the metals than what it previously held. However, this is limited. The mage is restricted to recieving a total of four various modes. While one can still consume a variety of metals, the user will no longer recieve a mode from it, and consumin a metal which the body does not adapt to and creates a mode from can be potentionally toxic to the body if consumed in any considerable amounts.
