Magic Caster Unit was the tentative name of a military unit composed of all the magic casters in the city of E-Naüru during the Battle of E-Naüru.


The concept of a synchronized magic caster unit has been entertained in the New World. It was noted that if such a group was formed into an army corp out of people who learnt [Magic Arrow], it would probably see a lot of success. However because it was necessary to learn even the beginner’s level of the first tier of spells required a certain amount of potential, never-mind the amount of time that had to be invested to educate a magic caster and given the same amount of time and resources, it was more beneficial to train a hundred archers than a single magic caster for combat.

Thus no historical records existed of such a tactic being used. So the idea of a magic caster unit was thought to be an ex-pipe dream of an army unit.

The group was formed in desperation by the E-Naüru's lord, Count Naüa to call every magic caster in the city to join them in mounting a defense, in hopes that he could form a unit comprised entirely of magic casters to combat the undead army from the Sorcerer Kingdom. The Count had sent requests to the city's organizations such as the Magician's Guild, the Temple of the Four Great Gods, the Adventurer's Guild and others.

Normally the organizations could not be called on to fight in a war, due to their unspoken rule, however they found a loophole. Since the Sorcerer Kingdom's army was comprised of undead — of which they were almost certain were the Kingdom’s civilians who were turned undead. They could basically treat it as a coincidence that this army of undead was carrying the Sorcerous Kingdom’s flag. Using this reason allowed the groups to excuse themselves from refusing a fight with the undead who could turn dead villagers into more undead.

Due to the fact that the Adventurer’s Guild had the most magic casters and the adventurers had plenty of experience with combat, the highest-ranked adventurer group, Four Armaments, was chosen to lead this caster unit. [1]


The number of magic casters was less than fifty, but this quantity made for a more than formidable army unit. To have formed a caster unit out of the people here meant that together they could adopt the strategy of continually raining down [Magic Arrow]s on the enemy, could theoretically slay even dragons.

Unlike regular arrows, [Magic Arrow]s were guaranteed to hit independent of the evoker’s skills. Casting it at a higher tier would increase the amount of projectiles generated as well as the individual damage output of each projectile. Even so, a single projectile’s damage output was still minuscule. It was pretty much impossible for them to one-shot their enemies with a single cast. The damage output of the spell did not depend on where the enemy was struck, which some considered to be its advantage while others believed that it was its flaw.

Behind this ex-pipe dream of an army unit were the soldiers under the Count’s employ and adventurers who were skilled in archery and other ranged weaponry.

  • The Sorcerer Kingdom was technically the first to employ the idea, via its affiliate group the Goblin Army which relies on two magic caster units: the Goblin Magic Support Corps and the Goblin Magic Bombardment Squad.
  • If there existed some organism that could innately use [Magic Arrow] and an army was formed out of them, that had the potential to be absolutely terrifying. Even if those requirements for talent could be met, it was safer to say that it was precisely because no such organism existed that an army composed purely of magic casters was only a pipe dream.
