Bakudō

Explanation

 * Supplementary spells which can immobilize an enemy or have an effect besides a direct strike. They may seem subtle, but these spells can give their users a tactical advantage when used properly.[2] These are a broad category of defensive spells which block/repel attacks or freezes enemies in place. This class of spells include Kidō Barriers & Seals.

Types

 * Barriers (結界, Kekkai): Focused spiritual energy formed into a solid form of energy. This energy can take on many shapes or colors as determined by the user. Barriers are protective in nature, and can be as simple as a barrier only protecting one direction or encompassing all sides of an area. Barriers can be used for containment, and some barriers can be used offensively. Barriers can mask spiritual pressure and can make one spiritually and physically invisible. The strength of a barrier is dependent upon the power of the user. Weak barriers are easily breakable, while strong ones can last for centuries. Barriers created by noble blood are said to be unbreakable by those of lesser status. Certain barriers can be placed beforehand and activated later, while others require certain artifacts and time to activate.
 * Seals (封, Fū): Somewhat similar to barriers, but far more powerful and require far more preparation to create. Seals can only be used by those of sufficient spiritual power, and are meant to hold the most powerful and/or dangerous artifacts or beings. Seals are usually hard to break.
