Heavenly Vow, a technique not naturally within, unlike binding or Final oaths, allows the greatest release of both cursed and blessed techniques. It's accessible to anyone except those who've committed blasphemy without seeking redemption.
While chanting, one must promptly state their offer followed by their wish. The order can be reversed without affecting the likelihood of it being heard or accepted. However, it's not a guarantee that your vow will be accepted.
Many perished after their vows were viewed—too greedy, imperative, or against heavenly preferences. Nonetheless, those whose vows are accepted become what they desire. In exchange, some transform into eternal angels, fighting for God forever.
The Heavenly Vow is said to be most potent when taken on the brink of despair or desperation, altering one's personality to attain a goal.
