Chapitre 250: 250

The concept of this formation was for any army to become one—not to the extent of sharing thoughts but to the extent where the mana in everyone partaking runs in the same route. At the same time, the army would be able to use themselves as runes to achieve different effects.

For example, when the formation is deployed, and a rune for healing is drawn, for an extended period, you would have an undying army that can still fight as long as their head isn't taken off. The mana energy everyone is sharing would push the healing effect of the rune to its highest, meaning a soldier who lost an arm could immediately get a new one by paying the price of lesser energy.

The most important requirement for this formation is the generals, who are the focal points of the energy build-up. While they are the focal points and most important, they are also the ones in the most danger.
