Shamanic Oracle

Shamanic Oracle (巫門遁甲) is a divination technique in the Chō-Senjiryakketsu. It enables the user to read an opponent's Furyoku and dodge their attack. This technique is one of the first things Asakura Hao teaches his followers.

About
When an opponent attacks, the user analyzes the opponent's Furyoku, detecting the subtle changes, and predicts the route of the attack. The user can then ride the flow of Furyoku, dodging the attack and placing themselves in a more advantageous position to counterattack. While using this technique, the user's Furyoku must remain calm and flexible, or else they will take the full force of their opponent's attack.

This technique also allows the user to react to and evade most surprise attacks.

Trivia

 * It is a reference to Kimon Tonkō (奇門遁甲), an astrological method of divination originating in China. The divining board is illustrated behind some instances of this technique in the series.
