Overview

Deprimo is a spell which blasts holes in things.

Extended Description

We see this spell in Harry Potter and the Deathly Hallows when Hermione uses it to blast a hole in the floor of Xenophilius Lovegood's house, as she, Harry and Ron make their escape from Selwyn and Travers.

Analysis

From the circumstances in which this is used, we can gather something about the spell. Hermione does not want to hurt the Death Eaters; she is trying to save Xeno from further torture at their hands, so she wants them to see that she and Harry were actually there, as Xeno had reported. She would have avoided a spell that would cause the floor to explode, which would have hurt her, Harry, and Ron, who were standing on it, as well as the Death Eaters. Similarly, a spell that would cause the floor to fall in might fall on the Death Eaters, and could also mask the presence of Harry. So the Deprimo spell almost certainly makes the floor vanish, and any explosion-like effects are caused by the remainder of the house as its already weakened structure is further damaged by the removal of a chunk of floor.

The effect is likely similar to the Reductor spell, which seems to be intended to turn objects to dust, rather than the Confringo or Expulso spells.
