Flora Release: Grass Whistle

After weaving the needed hand seals, the user picks up a blade of grass and channels chakra into it. They then make a grass whistle out of it and blows on it like an instrument. This technique usually has two effects. Normally, the user can play the whistle to stimulate plant growth and strengthen plants to be used as jutsu. Another offensive use for it is to create a shrill whistle that has such a high sound frequency, it can seriously damage a person's ear canals. Prolonged exposure to the whistle normally leads to the target passing out, though stronger targets can be stunned from the pain.
