Research into arrays was also a rather specialized school among Mages.
The essence of an array was magic itself, except that it reproduced the circuit structures running within the human body by using mana outside the body.
Naturally, it was more difficult than ordinary spells. When constructing an array corresponding to any given spell, one would encounter all sorts of strange and unusual problems.
After all, conventional spell systems had arisen based on the human body. Once separated from the body, certain things changed.
Simply copying the circuits could not reproduce an array, so related testing and adjustments were necessary.
Some could be completed through adjustments, while others could not be completed no matter what...
Arrays were still very useful, mainly in terms of functionality.
For example, Magic Crystals containing spells were made by constructing arrays for the corresponding magic within them.
After all, while Magic Crystals could store mana, they could only store mana.
To allow people who could not use magic, or who did not even possess mana, to use magic, it had to be achieved through "arrays."
Even the "Mana Network" used by the Association had originated from research into arrays.
However, in immediate combat, arrays generally had little value because they took far longer to construct than ordinary spells.
Unless the battle took place in a fixed location, where the battlefield was known beforehand and arrays could be arranged in advance. In that case, they could indeed produce remarkable results.
For example, during the Goblin Siege Battle at Silver Creek City, if there had been a Mage skilled in arrays within the city, they could have set up arrays beyond the battle lines beforehand and triggered them once the Goblins entered the area.
This method was essentially a more advanced kind of magic trap.
It simply
