Movement Masking

Movement Masking is a technique where the user educes a genjutsu around their vicinity and mask their movements. For example, when throwing a left hook, people can tell a person is about to throw one because of the movement of their arm. Another movement would be a liner dash, the opponent would be able to tell a straight movement. Its the same thing with just about most movements, but with this technique, the user can mask those movements making it impossible to predict what they are about to do. It almost makes the user invisible unless they don't move which in a fighting situation is almost never. To make the technique even more difficult to deal with, it isn't just one genjutsu, it a continuous genjutsu the user does using Yin Release. So if broken, a few seconds later the genjutsu will just be educed again as long as they keep funneling Yin Release chakra into the genjutsu.
