"I had Stealth Sensoring Spells placed all around my doorway after the last one got in, you foolish boy."
Dolores Umbridge to Harry Potter[src]

The Stealth Sensoring Spell (unknown incantation) was a spell that detected those under magical disguise.


In 1996, Dolores Umbridge had these cast this around her office at Hogwarts School of Witchcraft and Wizardry after two nifflers were placed there.[1]
