Angel Fall

Angel Fall (天照らす大地, エンジェル・フォール, Enjeru Fōru; Japanese for "Heavenly Illumination on Earth") is an advanced Angel Magic spell that allows one to directly interact with the summoned Angels in order to gain a temporary boost of power. There are two forms of the spell. The one most commonly seen is Raiment (衣, Koromo), where one enshrouds themselves in an Angel's power. The other is Vessel (器, Utsuwa), where the Angel and caster's power is directly fused for a greater amount of power, at proportionately higher risk.

Trivia

 * The name Angel Fall was taken from the arc of the same name in the Light Novel, Anime and Manga series.
