The curse-dependent locking spell (incantation unknown) was a spell of the Dark Arts that tied the integrity of a lock to a floating eye curse somewhere else in place.[1]


Once cast, a floating eye would then glide before the door to be protected, moving through the air before it in a circle, with any other number of eyes present reflecting the number of floating eye curses attached to the spell. Once all the curses defending the lock had been lifted this spell would also lift, unlocking the door it guarded.[1]

Behind the scenes

  • It is possible that this spell could also work in conjunction with other magic, as opposed to only the floating eyes curse.
  • This spell may be one of the Alohomora-proof door-sealing spells that Harry Potter speculated on in Harry Potter and the Order of the Phoenix. It may even have been used in that same book by Dolores Umbridge on her office door, albeit in conjunction with some invisible magic instead of the floating eyes curse, so that no display would appear before the door, as is the case with this spell when it is used with the floating eyes curse. If so, then this spell could be broken by Sirius Black's knife.
  • In a way, the way this spell acts can be compared to the mechanism of a Horcrux, because the door remains locked until all of the independent Floating eye curses have been dispelled.
