Silence Release

is a specialised  that can produce the silence around the user, or rather absorbs all the sounds of the surroundings. First, opponents are deafened by a huge high-pitched sound, making the transition, and then, their hearing are affected and can not hear anything, not even their own voice. Then, they become disoriented, confused, and the user can walk around without fear of being spotted or preparing his surprise attack in a hiding place.
