A special state when the resonance between a magi and the background noise of the Æther Field is perfectly constructive, leading to a runaway effect and being able to cast magic (sequence) at an efficiency greater than 100%.
Until the achievement of this state by Rho, it was considered only theoretically possible by the boldest of Æther Field research in Primitia.
This state was common among the seraphs of world pre-Primitian Initiative. It is used to explain their effortless interfacing with the Field and is perfect response to their will.
