Deifacted nethicite is too strong to be controlled properly, and dangerous when it cannot be. Manufacted nethicite is weaker, but safer and easier to use. Nethicite can disrupt magickal energy and machines that rely on it with its presence, and can absorb magickal attacks. Charged with Mist, it can create skystones resistant to jagd, be used to summon Espers, and can even be implanted in a person's body to augment their physical strength and magickal abilities, although such use of nethicite damages one's sanity.
