Miêu tả thêm[sửa]
Harry finds this spell in the Potions text that belonged to the Half-Blood Prince. He uses it at one point in the story to silence Peeves, who is loudly commentating a fight between Dobby and Kreacher. We also guess that this is the spell left in the entrance to Number 12, Grimmauld Place by Mad-Eye Moody as part of the attempt to prevent Snape's entrance.
