Helmet Magic is a Holder Type Magic used by various mages. Alongside Requip, this is one of the most common magics in existence.

Description
The user starts by channeling Eternano directly into a specially constructed magic helmet that causes a chain reaction to the Helmet, having the helmet alter it's entire structure until it reaches an unstable form of metal and magic, allowing the person to manipulate it into a solid shape that can also engage the spell that the user sees fit to use. In some cases, when the person condenses the unstable structure, they often add their own elemental affinity magic, allowing for the user of elemental helmet spells to be created through the effective means of the user. During the time after the helmet spell is used, the Eternano is immediately ejected from the helmet, allowing the unstability, the result from the Eternano, to cease and transform the helmet back to it's normal shape. However, there are certain risks to using his magic as it takes much mental focus and incredible magic control in order to allow the helmet to be altered in it's solid shape, and to be controlled in it's unstable form. When the user often attempts to make any spell, their hand is to remain on the hilt at all time, due to the fact that unless the Eternano is controlled and is kept at a steady flow into the helmet, the helmet will simply revert back to it's normal shape while the Eternano is simply ejected outward.
