The ghosts in the Sain Dungeon can't be attacked without using a Temporary Curse, which seems to be close to some sort of rule.
Based on years of experience analyzing monsters, it's impossible for a Low Tier monster to have rule-type abilities; that would be too much of a cheat.

Unfortunately, even after they ran back to the Fire Transmission Ceremony, Anleisi still couldn't make sense of the Temporary Curse; the curse itself left her perplexed.
But that doesn't matter anymore, because the moment they stepped into the Fire Transmission Ceremony, everyone's attention shifted from the Temporary Curse or the Little Londo Ruins to a doorframe standing by the bonfire.
