Shifting Ink Genjutsu

This is a specialized Genjutsu that is deployed in the form of a hand written letter. The ink used to create the letter presents itself to the target in the form of whatever the user want the target to read, while it is actually a written Genjutsu seal. When the target reads the seal, they comply with any suggestions or orders presented in the letter and believe everything word for word, without even realizing they are under genjutus. Although this technique requires a high level of skill to preform, the seal will not work on individuals with any special forms of Genjutsu defense.
