Energy Harness

Energy Harness(エネルギーハーネス Enerugī Hānesu) is a form of Caster Magic that originated in the Realm of Dusk and is never usually found on Earth Land. It allows a user to charge up the magical energy within them and incorporate that energy to perform extremely powerful blows that can destroy the ground, bones and even objects.

Despite it being from such an evil realm, it is not taboo to preform this magic. The only being on Earth Land capable of teaching this magic is Blakeley Quell, who is originally from the Realm of Dusk but was banished by her younger brother after a dispute over the throne. At one point, she passes down this magic to Gia Alabaster after the young knight becomes her student.

Overview
This magic allows the user to continuously build up the magic energy inside them, which increases the number of damage they would do by double. However, this does not mean the user has an infinite supply of Magic Power. In fact, if the caster excessively builds up the magic power within them without releasing it, the energy releases within the body could clog up and completely stop the ability.

Energy Harness does not extend to partners, meaning that it is not used as an Enchantment spell to boost the power of others. It is actually impossible to do so because this ability relies on the magic energy of only one Mage. Not every Mage has the same amount of magic power to handle this ability.

Many Demons, or Etherious as referred to by humans, have this ability due to their super-human abilities and ability to harness more than the average amount of magic power.
