|Actus Noctis Erebeae|
|Romaji||Kuraki Yoru no Kata|
|English||Form of the Dark Night|
One of Negi's Magia Erebea forms. It is a way to activate Magia Erebea without needing to absorb any spells.
A way of practicing dark magic. In Latin, it means “gesture of dark night.” The translation of “gesture” into “form” refers to the series of actions in which those gestures come together. It is a form in which the caster can store magical spells within themselves without canceling the previous Magia Erebea. By incanting "Supplementum", they will absorb the magic into themselves, but not merge with it, where they can release it at a later time. The power of this form can be used in any Magia Erebea form. The actual syntax varies slightly, depending upon the nature of the command given.
