[Harry Potter] Is the Patronus spell really the only thing that can take down a dementor?

Surely if a bunch of people do Bombarda Maxima or Sectumsempra on a dementor, it would scurry away instead of continuing to try to suck somebody. I know that they're living creatures so surely they must have an urge to retreat when blasted with spells they can't respond back to


Also, if you focused on a spell that was pure hatred/sadness would they be repelled by it? They enjoy happiness so, wouldn't hatred "taste bad" to them?

Not exactly. Dementors are what wizards call amortal. They're not alive and can't die. Ghosts are also amortal, for another example, as are poltergeists.

Dementors don't fear destructive spells because they know they can't be harmed by them.
