Magicka

Magicka is a special type of element that is created through ancient alchemy techniques. They function similar to augment crystals, with two notable exceptions. The first is that they will only function in items that are designed to use magicka, the second is that they may be used interchangeably between weapons and armor.

Those that are trained in the ways of Magicka (called Terramentalists), also have the ability to draw power from the stones directly and channel it through themselves.
