Eon Luster: Infinity Lance

Eon Luster: Infinity Lance(明るい・永遠の渦, Akarui eien no uzu): is an offensive spell and a Dragon Slayer Secret Art, which makes it one of the most powerful spells within the practice of Eden Dragon Slayer Magic. It is a long to medium ranged spell capable of being used against a single or multiple opponents. When cast, giant currents of spiraling aurora-light are launched at the enemy with a shredding force great enough to tear through even the pinnacle of defensive magics. It is because of this property that it is most commonly used as a finishing move by the wizard, Cyrus Baryeon.

Description
To cast this tremendous Dragon Slayer ability, the mage begins by drawing a ring of magic energy in the air. The caster's arms are then held closely to the left side of their body and collects a huge volume of ethernano in their hand. Upon completion, the spell is cast, the collected magic power is discharged with a thrust of the mage's arm, and the massive reservoir of ethernano is ignited, causing numerous currents of dense aurora-light to burst forth. The stream of light are twisted in a torrent, which can then be fired at opponents over a long to medium distance. The tearing force contained in the torrent, combined with the divine strength of aurora-light, grants the spell incredible sawing power, enough to rip apart the ethernano composition of most magic spells; however, the more powerful the opponents magic, the more the power of the spell can be dampened before impact. While not traditional, this spell can be fired into a horde of enemies into order to wipe out scores of soldiers in a single blow; however, the drawback is that the tremendous amount of magic power required to cast this spell often leaves the caster exhausted and vulnerable to a counterattack from a strong opponent. For this reason, this spell is used more commonly as a finishing move during one-on-one combat. After the duration of a long battle against a formidable enemy wizard, fatigue prevents the opponent from casting a defensive spell strong enough block the destructive force of this secret art.
