Reveals human presence
When the spell is cast, anyone near to the caster will feel a strange sensation, as though something were swooping low over him or her, immersing them in its shadow. If there is nobody nearby to the caster, then nothing will happen whatsoever; the caster, however, will immediately be warned in either circumstance.
Behind the scenesEdit
- In the film, Travers does not use this spell; rather, four or five Death Eaters encircle the house and fly through it, causing it to collapse, and then the trio disapparate.
