Incantations

Incantations, otherwise known as magical words, are sequence of declaration statements - typically used by Priestesses or Necromancers in effort to mold their Mana. In the process, it directly enables an individual to use a range of different spell types, such as dark magic, light magic, curses, or even healing abilities. Naturally, Incantations are often compared to hand seals, as both serve the function of enabling an individual to use their chakra, or mana. However, at least in the eastern world, incantations are seen as the superior of the two.

Overview
Incantations, like hand seals, are a special means of activating the surges of energy lingering within the body. However, while incantations do make use of the Mana Circuits - the primary focus is pumping the energy directly from the tap, allowing it to speedily flow along the invisible pathway, and out of the user's body. Nevertheless, the means of which these incantations are spawned still remain a mystery.

When creating new techniques, the words are said to simply 'come' into the developer's mind.

It's theorized that the magical incantations spawn from an individual's Kotodama or kototama (言霊?, lit. "word spirit/soul"), as that part of the spirit maps out the necessary components needed to use a particular spell or power. In addition, the Seinau and Kokonerasu have both gone at length to record common incantations that can be used, or stringed together in an abundant of ways - each effecting the underlying manner in which a person can manipulate their chi.

Nevertheless, being a direct relative to one's capacity to mold, manipulate, and discharge their mana, the more proficient a user is with their abilities, the less incantations that will be needed. Some may even gain enough skill to fire off certain techniques with no spell words at all.
