Onmyoujutsu

Onmyoujutsu (陰陽術, "Art of Duality") is a form of Onmyouji combat based on advanced spells. These spells are produced with strong Magical Energy and fall into two categories. Yōton for direct combat and Inton for battle support. Each spell is performed using various handseals that derive from the 12 Zodiac Animals. Experienced users can perform them with lesser handseals or not use any, although their effectiveness and power can be diminished.
