Magiln

A red metal that is used by warriors in order to combat against mages. They most commonly use it on a bladed shield in which splits the energy in two, then, eventually, is slammed into the enemy mage as a weapon.

Properties
It has the mysterious ability to reflect or cut pure energy or plasma. After the energy hits the metal twice, it is absorbed and then vanishes from existence.

History
It's unknown how it was discovered, though some believe it was created by the True Mages, though some argue that even the True Mage weren't powerful enough to spread it across the world.
