Sealing Technique: Demonic Illusion

Sealing Technique: Demonic Illusion (封印術・魔幻, Fūinjutsu: Magen) is a developed by Shenron Uzumaki as a method to increase the difficulty of releasing Genjutsu. Throughout Shinobi history, ninja have developed numerous methods to break free from various illusion techniques including: disturbing one's chakra flow, inflicting pain onto themselves or noticing even the most minute detail. With genjutsu becoming less effective amongst the highest ranking combatants, the Second Uzushiokage developed this technique in order to make even the simplest of illusion difficult to remove.

The technique's design is not complex but it's however quite effective. Taking an illusion-based technique as a parameter, the user places the seal onto the target. As if the technique were casted through ordinary means, the illusion takes effect. If the target attempts to break free from the illusion the secondary effect takes place. As the seal is not dependent on the target's chakra flow but rather the chakra of the seal, the illusion cannot be dispelled until the seal is broken.

This technique is not without weakness however. Unlike many genjutsu that can casted through various mediums, this technique requires the user to make physical contact with the target despite the original parameters of the parent technique. Also, the potency of the seal is entirely dependent on the caster's proficiency in Fūinjutsu.
