Curse-dependent locking spell

The locking spell (incantation unknown) is a spell of the Dark Arts that ties the integrity of a lock to a floating eye curse somewhere else in place. One or more floating eyes will then glide before the door, moving through the air before it in a circle, with the number of eyes present relecting the number of floating eye curses attached to the spell. Once all the curses defending the lock have been lifted this spell will also lift, unlocking the door it guarded.
