Gungnir's Wrath

Gungnir's Wrath (グングニル怒り,'Gunguniru ikari') is an exceptionally powerful offensive Nullification magic spell that transforms the magic sword, Illyria (イリュリア, Iryuria), in the image of the massive celestial pike, Gungnir, wielded only in legend by the strongest of Gods. An infamous spell, tales of its destructive power have inspired fear into the hearts of the weak. It was through the use of this spell that Gilan earned the epithet, “The Gate of Oblivion” (オブリビオンの門, Oburibion No Mon), after wiping an entire Fortress off the face of the earth during a mission.

Description
A true testament to Gilan's skill in utilizing the shape-changing properties of the magic sword, Illyria, the intricate design of the massive construct was inspired by cave drawings depicting the legendary spear of the Gods, Gungnir. Named after its inspiration, the spell consists of a transformed Illyria blade taking the form of an ornate, square based spear head surrounded by seven smaller prongs that revolve around the larger portion. When fired, the central head rotates quickly and is trailed by an enormous tail of furiously spiraling ethernano, capable of tearing anyone caught in the tailwind limb from limb. Due to the projectiles infusion with Gilan's Nullification Magic, the weapon cannot be blocked by magical construct, and its implicit magical immunity also increases the power of magic spell necessary to stop it from achieving total annihilation. Additionally, the caster has complete control over the angle and trajectory through which the weapon is fired, granting Gilan substantially more flexibility during the casting of this spell, enabling him to fire the ranged weapon with tremendous accuracy. As is the nature of magic this powerful, the activation of this spell requires tremendous amounts of magic power, such that inappropriate use of its power will leave the caster exhausted of magic power, and unable to fight if the spell is not used effectively.
